Mikrokhvilova pich: self-repair is not a problem! Repair of Panasonic inverter microwave ovens Repair of microwave oven inverter

Golovna / Korisne PZ

I hate flooding on the forums, but once you happen to be a victim.

Have you ever been in Sochi Vletka? Just lean back here, respectfully marvel at the facades of richly superficial ceilings, and rejoice, how many air conditioners work at once. Sweat away, skilki hotels, cafes that are far away from one hectare. Food falls by itself.

Have you looked in the middle of the micro-furnace? Yakby dropped in, then they wouldn’t put such power supply. In this model, the lower part of the fan diffuser is located just above the upper cover of the plastic box of the inverter.

It is immediately clear that you were not friends with physics at school, otherwise you would know that the Crimea is radioactive, and other types of radiation, including thermal radiation. In my post, for saving money, I omitted the whole word, relying on the elementary technical literacy of people, like reading this post. As it is necessary to heat the walls of the shafi, then, as you mentioned, the cream of all other modes, in this model there is a mode of sleeping robot and micro-furnace and grill. My friend, for example, often cooks curcha-grill, vicorist in the same mode. With this, the temperature in the chamber reaches 250 degrees and more.

Nourishing zayve (like everything in the past), but I’m all the same receptive. In the whole world, in the circuitry of the keys, which are used by the convertibles, the connection of the stabilitrons is adopted the same way, I wrote about it. You can put them on the pack.

I wouldn’t have become a stained glass for an hour of the shanovnyh members of the forum, like reading that my post, yakby before yoga, I didn’t check with the qiєyu (and similar) micro-hvilov oven a number of samples.
I installed "relevant" firm transistors in the inverter and turned on the micro-flute oven in the micro-flute mode at maximum intensity. With which voltage, I installed 230V. After 15 minutes of work, the inverter radiator used to heat up the flooring, so that the finger on the new one could not be removed for a long time (behind the thermometer is close to 80 gr.).
After reaching the radiator, I repeated the test, but now at a voltage of 245V. For the first time, the temperature of the radiator after 15 hvilin folded already 120 gr.
With transistors SKW30N60HS, for the silence of the minds of the re-verification, the temperature of the radiator was folded to 50 and 80 degrees.
I want to make sure that I don’t earn a penny with repairs (I’m on a living with a whole lot of work and pensions), and I take on the repair of folding electronic outbuildings only in that case, because the workers could not repair them, otherwise they didn’t undertake these repairs - on their own instance" for the unfortunate Vlasniks of the SBT. However, when repairing such outbuildings, I don’t just stupidly change the “driven in” components, but I try to find the reason for the failure of their way out, and, if possible, improve the circuitry, or I’ll build the design of the outbuilding itself, with the method of increasing its reliability. Even the annex that passed through my hands will not turn back before me.
I ask the moderators to sing me for the flood, but I’m more likely to vouch for the flood of the shanovny intact.
And vishanovny, try not to make the forum more dirty with marny posts. As if you have nothing to say in essence, those who would rather not write anything.

Microhvilyova (HF) of the Panasonic NN-G335 is a distant model, both in design and in functionality. The dosі tsya model is not known for its modifications, but only for a small restyling. Pekti can turn on the handle for opening the door, it is provided with a grill and electronic (touch) controls. Irrespective of the high price of its class, Panasonic NN-G335 is a great drink among buyers. What is the point in operation from a look at the reliability of electronic and mechanical nodes?

Let's take a look at all the inaccuracies in order, which were blamed on the author of the article for the quality of the micro-fingerprint from the moment of purchase (2006 rіk) and until the next day.
The first thing you start to flirt with is a very loud signal from the speaker. So I want to pick up a pich, so that I can seal the sound opening. Ale, unfailingly, you call to this one and, sometimes, you want to praise the retailers in the micro-furnace oven for the far-reaching signal about the readiness of the strain, which is very noticeable when you turn on the house music.
The main unacceptable moment in operation is the bottom of the oven chamber, which can swell to corrosion (irzhavinnya) there, where there is a plastic ring of the rotary plate.

Rust bottom of the chamber.

Approximately for three years of operation, the bottom of the chamber was severely corroded. Imovirno, the cause of the corrosion was the high water content and the rubbing of the wheels on the turntable. Following the detection of such a defect in the chamber, for the help of an ultrahigh-frequency detector, it was necessary to re-check the furnace for a round of vibrating. Everything turned out to be normal. The old building is good on the screen, regardless of the great ruination of the camera.
On another operation, the camera's light bulb burned out. Breakage zovsіm is not terrible that is easily usuvna. It is necessary: open the fire (take off the cover), remove the darts on the lamp, take the lamp and install a new one. However, the lamp there is not victorious, but is special for low-frequency furnaces (the base is not threaded, but looks like two contacts). Buying a lamp is no problem. In the extreme fall, you can put a great lamp, having come up with a way of fixing and connecting the wires of life.

Lamp lighting.
To shine through small gaps, open directly into the camera .

On the third rotation of exploitation, one "beautiful" moment was taken care of (the scoreboard did not light up, there was no sign of life). After the opening of the body in the first line, the thermostats were overturned, and at the same time, an inaccuracy was found - one of the thermostats was in a permanently open state. The Panasonic NN-G335 oven has two such thermostats, which are offended when the temperature of the thermostat housing is heated above the nominal temperature (indicated on the thermostat housing). In order to replace the thermostat, which is good, in a micro-furnace, it is necessary to know the temperature of the thermostat setting, which is good, the working jet of switching, the type of switching (on or on) and the type of housing (looking ). I didn’t know such a thermostat itself (behind the fasteners). It’s not scary, it’s a smut - make sure that the thermal contact between the thermostat housing and the object housing is maintained (details of the furnace design, on which the wines are installed).

Replacement thermostat. Installations behind the auxiliary pressure plate and screws (photo on the right).

It is important to say what caused the failure of the thermostat. Shvidsche for everything, the reason is just at the hour, even if everything is your term of service. Yakby mav place overheating, for example, through the close of the outer ventilation slots, then after turning on the stove and reaching it, the right thermostat is guilty of re-mikating, which did not happen.
І stop, for which it happened to shut up - burnt out the protector of life through the spratsyuvannya of the zahisny diode.

Zapobіzhnik, scho burned out (8 A).

Written on a high-voltage capacitor (right-handed photo).

In order to know the reason for the operation of the 2X062H і, as a last resort, the burning of the fusible protector, the opir of the lancet of the ignition of the magnetron was overestimated, it appeared superficially small (close to 0.1 Ohm), we could not exactly measure it with a powerful multimeter. For the known proof data to this magnetron, such a low reference has become normal for a reference magnetron, or rather, it can be 0.07 Ohm. So it was overwhelmed by the opir mizh the magnetron case and yogo with visnovkas, the opir appeared "indistinct", as it can be. From the cycles of vimiriv, a number of wisps were made about the mental correctness of the magnetron (through the possibility of the greatest test). However, during the dismantling of the magnetron and the znyatti zahisnoy metal lid, after the overworld local heating of the coils was revealed (the enamel of the insulation is small darkening), but the conductor itself was not damaged. In order to change the mind of a high-voltage transformer, it was necessary to reconsider the operation of the constant stream of all windings. Opіr approximately zbіgavsya z dovіdkovimi dannymi. The results of the experiment were recorded with a fountain pen on the transformer itself for the possibility, if necessary, of re-verification again in the future.

It can be seen that the insulation of the coil was burnt (photo on the right).

As a result, it was decided to replace the windshield with a larger high-intensity (10A), carry out folding and re-verify the robot. As it turned out, the decision was made. After the rest of the repair of the micro-windows, the work was carried out, there were no third-party noises or anomalous work. Obviously, as if to repair according to all the rules, it would be necessary to also replace the burnt out diode with a new one, but it was far from the lowest price, the hours near the radio store and the extreme need in the kitchen in the oven outweighed other arguments. For example, you can add more photos to the repair process.

Zvichayno, be it a master, that master will be covered, as if the VHF-p_ch raptom ceased to turn on or work with failures. The first thing you want to do is to take your loves and go to the nearest service center. If the micro-furnace is covered by a guarantee for the very same thing and the workmanship, but if not, then you will have to pay for the repair.

But as practice shows, more faults may be even more simple reasons and people, as if you are using a tool and may be, you can make a clumsy repair on your own. Ale for whom next to know. Let's figure out why we can use this brown attachment?

The main faults of the micro-furnace oven are the result of incorrect operation of the low setting to the fitting. Factory defects and most often appear in the warranty term and are accepted by service centers free of charge.

Before that, as a self-supporting repair, a trace of knowledge about deeds come in safe with the robot zі NVCH-pіchchu.

For no reason at all, it was not possible to start the magnetron of the low-frequency oven with open doors, with a low chamber, or with a hvilevod.
No, and for the sake of everyday minds, it’s not possible to navit namagatisya to connect the magnetron by renting it from its regular position. Tse not safe for life!
Run low-frequency-pіch іz impractical fan blocked. Tse mozhe vivesti z fret magnetron.
Viroblyat whether-like manipulations with the details of the furnace is possible only after vimknennya from the measure of the primus discharge of the high-voltage capacitor.
It is necessary to replace all the elements on similar ones.
After the completion of all the work, it is necessary to see everything, to find the most important objects from the hvilevod.
The launch of a micro-furnace without prefabrication has been blocked. At the camera, you need to put a non-metal sac with water.

When arranging a micro-furnace, it is the best way to photograph leather croque, so that we can easily see the cob position and fastening of all details. Digital cameras and mobile phones will be here to help.

Why the HF-pіch does not turn on and does not react to the input of the door and on the control

Let's look at how we can explain the possible causes of such a breakdown. In this case, we will change the need to reconsider the voltage supply on the mesh filter board. For this purpose, after the opening of the casing, a high-voltage capacitor is charged (an operation after the skin connection of the membrane) and the life cord is called with a multimeter. All three darts from the socket until the clams are called. The grounding terminal on the rosette is to be called to the body of the low-frequency oven. You can read about the methods for detecting capacitor malfunctions.

If you see the tsiliy, then you can reverse the tsilisnіst merezhnogo zapobіzhnik, which is the most frequent change on the payment of the filter of life, and at the same time you need to replace it with the same denomination. Ale sled vrahuvati, scho zapobіzhnik just does not burn, є as a reason, yak called to revantazhennia.

In any case, it is necessary to conduct a visual inspection of the insides of the micro-furnace. For whom it is necessary to take a lighter and a magnifying glass carefully look at all the elements.

The presence of darkness, having opened the breakdowns, swollen electrical capacitors, began to talk about abnormal processes. I’ll look around for an hour and help sniffing the details. The smell of burning insulation, other boards or transformer olії bezpomilkovo vznachaetsya, and even the problem can be localized.

The lamp is on, the table wraps around at startup, but it doesn’t glow

If the micro-wave oven turns on and works, but if it doesn’t, then you can tell about the faults in the high-voltage lance or the magnetron itself. Ale in front of them, as perveryati tsі components, next respectfully look around the camera. It is not to blame for the daily zabrudnen, worn out enamel, scorched openings. On the left side of the chamber, straight at the end, made from a special radio-transparent dielectric. It is necessary to take a dress and respectfully look at it.

It is necessary to clean the back of the head with alcohol, and then perekonatisya, as there are no nasty leaks, opening or darkening in the surge of electrical discharges. If so, then, in a better way, this detail makes a change, but, in a different way, it’s redundant to talk about those that the VHF-p_ch could be launched without interference, otherwise metal objects were placed in the chamber, otherwise they didn’t clean themselves in their own time.

A high-voltage magnetron magnetron has such important elements as a transformer, a high-voltage capacitor and a diode, as well as outside diode, which lights up in random modes. It is even easier to know where the transformer is, when it is located in a special container. Yogo zovnіshnіy looking at once show yogo camp. When replacing, it is necessary to add an outside diode only with equal ratings.

high voltage transformer next call only when the first winding is switched on. Vimknuti yogo is even simpler - you need to take klemi with pliers. Opir primary winding can be close to 1.5 Ohm, secondary high-voltage 110-120 Ohm, and secondary winding voltage less than 0.1 Ohm. As if the windings are not ringing, such a transformer needs to be replaced.

Magnetron maє roz'єm, yakim vin is connected to the transformer. When you see the terminal, you need to ring the opir between the terminals and the case and if the stench is heard, it’s worth talking about the breakdown of the passing capacitors at the filter. The filter can be changed as an assembly, or a capacitor of the required nominal value can be used.

Having hired the magnetron from its regular position, you can evaluate the antenna's winding frame, and if it burns out, then it will make an unambiguous replacement. Only a few minats are needed for such a rosemary - it’s even more important! Vodnochas it is possible to evaluate the camp of the insulator to the magnetron. Chi pierced the antenna of the yoga body unequivocally allowed to replace the magnetron. With a trivial term of service of a micro-furnace, it can be cost-effective.

If after all the entries of the micro-wave oven still does not start, then you can proceed to the diagnostics of the blocking system. On the back, the tightness of the closeness of the doors of the low-frequency oven and the superficiality of the zamikannya are turned over. Tse to fight for the help of Arkush Paperu. At the closed camp, the papier is obliged to snuggle along the entire perimeter of the doors so that it is impossible for him to pull through, or with great difficulties.

Even if the doors are closed, it is possible to put an arch paper under it, then the doors will require adjustment.

Adjustment is carried out at two places: from the side of the loops and the lock. It is necessary to reach the full and narrow fit, otherwise the low frequency bands can be penetrated beyond the micro-furnace. Then we control micropermeabilities in open and closed camps - the stench is called by a tester. If only one is unfair, they all change one and all, to the fact that stinks can be approximately equal to wear.

Incorrect block keruvannya

If all attempts to start the micro-wave oven in the lantern and the high-voltage part were not successful, you can proceed to rechecking the control unit. The management fee is charged and carried out through a visual inspection with a magnifying glass.

On the large boards there is a fusible protector, which burns in an instant. The station of the road, the presence of a garou and blown capacitors, broken diodes and stabilitrons - all to talk about problems. The life transformer can be rung only by soldering it out of the payment.

Vrakhovuyuchi different models and circuits of low-frequency furnaces, further recommendations for repair of the control unit will be stupid. The leather is unique and if the master does not know what they gave to work, then it is better to entrust everything to the fakhivtsy and, if necessary, to be thoughtful of them, which is more likely to be required to grow from the very cob.

Podbags

Microhvilyova pich is a foldable and high-tech attachment that leads to a strong motivation and insane scoring of all the recommendations given by the picker.
Self-repair is possible only if the owner of a micro-furnace has knowledge in electrical engineering and electronics.
When repairing, follow the rules of safety when working with a boosted voltage and low-frequency vibration.
Replacement of the magnetron in the low-frequency furnace, which has served for over 5 years, is economically negligible.

Meister arrived at the specified address to update the functionality of the by-button technology. The owners of low-frequency furnaces are advised to continue the trouble-free operation of the unit.

Typical malfunctions of micro-furnaces

Panasonic microwave ovens are in operation. Breakdowns of equipment are blamed through the destruction of the rules of the rozіgrivu, if there is a sincere connection between the plug of the hvilevod and the magnetron. As a result, the antenna burns out and collapses, and the camera's enamel is also worn out. The practicality of baking a robot is fatally pouring in without venturing into maximum tension. The voltage cuts in the electrical circuits lead the electronics in harmony.

Modern low-frequency ovens are stable before such breakdowns:

Fault type	The reason for the vindication
Attachment does not get in	Revitalizing transformer failure
HF-pіch does not start	Breakdown of a high-voltage capacitor or a high-voltage diode
Selected program does not start	It is necessary to replace the processor pay management
The hour of preparation is not restored	Incorrect controller or control panel
Don't wrap around piddon	You will need to replace the electric motor or the gear reducer
You can't play	Trouble in the robotic magnetron or poor antenna
Daily indication of the selected program at the time of cooking	Trouble in the robot block keruvannya or malfunction of the PK-display
Do not increase the tightness of the rose	The inverter does not form the voltage (anode voltage), but replaces the magnetron.
Attachments do not automatically wiggle	Timer failure (for units with mechanical turning)
Uneven heating in the chamber	Shaving the drive belt of the dissector or fan, which cools the magnetron.
Do not use buttons on the panel	Shaving paths or sticky contacts
Grill integration not working	relay failure

In case of problems with the robot, I will add it quickly to the service center "A-Iceberg". Repair of Panasonic low-frequency ovens at home is carried out promptly and with a guarantee of quality. After a short period of time, you will be able to re-exploit the bottling equipment.

The kitchen helper is not folding, so in case of other malfunctions, it is necessary to repair the micro-furnace ovens. Repair of Samsung, MYSTERY MMW, Whirlpool, LG, Panasonic and other popular models is easy to do independently. To identify the inaccuracy and replace the details, it is enough to know the knowledge taken from the school and the memory of the soldering.

In order to repair the home of panasonic micro-furnaces with your own hands, you need to know the basic elements, so that you can take care of your work. Microhvilova pich, be Mister 2018g; otherwise, be it another way, it is composed of upcoming functional blocks:

a magnetron mounted behind a hvilevod chamber;
transformer;
high-voltage protector;
high voltage diode;
condenser;
control block.

Construction of a micro-furnace.

Elements of a micro-furnace.

Rotation magnetron at the center of the vіdsіku. The transformer, which is folded from a dial-up metal core with a coil, is located below. On the right side of the front there is a board with a capacitor, a diode and a protector. Block keruvannya sound roztashovaniya order from the panel for setting the modes of operation.

When the furnace is turned on, 2 voltages are applied to the secondary windings of the transformer - 6.3 and 2 kV.

Low voltage is applied to the magnetron string, and high voltage is applied to the voltage booster, which is formed from the diode and capacitor, and then to the anode. As a result, we blame the microwave cooking, which is vicorated by ovens for roasting and preparing hedgehogs. The tightness of the micro-flute is regulated by the help of the control unit of the micro-flute.

Appointment of inaccuracies

Skin breakage is accompanied by its own symptoms:

Use the middle of the oven to sing, crack and shoot. You should be careful when ruynuvanni mica lining, which closes the exit of the hvilevod into the chamber. Tezh vіdbuvaєtsya when burnt zahisnogo koppak magnetron.
Chi is not played, the hedgehog is placed in the cell. Piddon wraps around, pidsvіchuvannya pratsyuє. The problem is caused by the burnout of a high-voltage protector or by a breakdown of the capacitor.
Microkhvilova pich nasty grіє. Tse v_dbuvaєtsya through a low voltage in the electric circuit or use a magnetron emission.
Pekti is not included. On the back, the integrity of the cord of life is checked, and the presence of tension in the rosette is protected. Let's turn on the blocking switches, which will turn on when the doors are closed. Everything is in order - the reason is the oxidation of contacts in the thermal relay located on the magnetron case.
Chi does not turn around piddon. The clutch is broken, which drives the engine shaft with a pallet or the motor is faulty.
Under the hour of robotic pect, zokrema Mystery mmw, you see a lot of buzz. Faulty transformer chi fan.
Typed commands do not win. Possibly, through a high temperature, the contacts to the block of care were burnt.
Indication or the timer is not displayed. Destroyed the microprocessor robot. In such a case, the repair of the touch panel is carried out by the master.

Selection of a micro-furnace

For do-it-yourself repairs, it is necessary to provide access to the elements under the casing on the rear wall. For yoga, 6 bolts are twisted with a cross-like twist. In case of missing the elements, it is not necessary to spend an hour on the jokes of the screws or the bolts. To capture any element, it is necessary to press on the upper ledge. Fortified can be a sprat, before the win it is necessary to perekonatisya, stench of all znyat.

Before the opening of the casing, the life cord is connected to the outlet.

Shards of capacitors take charge for three hours, it is necessary to immediately discharge them, mimicking the whiskers against an insulated dart.

Do-it-yourself repair of low-frequency frequencies with your own hands is better for the additional functional scheme. Vaughn is universal to all stoves and to report on all the elements. Do-it-yourself repair of a micro-furnace lg can be carried out in accordance with the recommendations below.

Electrical principle diagram of a micro-furnace.

Micro-furnaces are equipped with two guards. The first in the glass case was installed on the input voltage from the socket. The integrity is checked visually with an ohmmeter. Another, high-voltage, in a tubular case made of plastic, is the expansion of a transformer. It burns when the fret of the diode or the capacitor of the high-voltage lancet magnetron exits. Do not replace them with "bugs", you can bring the shards to borrow. Before the installation of new guards, it is important to conduct an analysis of the reasons, which were called before the burnout, so that the situation does not repeat itself.

This is how the burnt zapobіzhnik looks.

Replacement of mica

During the process of rozіgіvu, that preparation of їzhi on a mica overlay is inevitably consumed by drops of fat and small pieces of їzhi, through which sparks and crackles sparkle in the chamber. Magnetron at tsyomu vpadku to bring pratsyuvati z perevantazhennyam, scho lead to the exit out of harmony. Leaves of mica are sold at radio stores, and you can buy a plate of the required size from leather. If there is no possibility of replacing it, then at the same time, after the cleaning of the vicorist, the old plate is cleaned, as if the zipped side is installed in the middle of the hvilevod.

Repair

A burnt-out cap, which is accompanied by noise and sparks, fades through old age, or afterward the mica plate is ruined. Therefore, when replacing the lining, it is necessary to change the binding of the leg. The detail is copied and easily changed. Ale, you can repair it simply by opening the cup by 180 °. The new camp of wines will serve for a long time.

Rechecking a high-voltage diode

For diagnosing these details, the normal tester is not suitable, the shards do not have a sufficient range of vimir. The re-testing can be carried out with the help of an extraordinary light bulb, by connecting it through a diode, which is re-tested up to a measure of 220 V. As a matter of fact, the detail is correct - the light bulb does not glow even when it is roasted. When the light is bright and bright, the diode is replaced.

Capacitors, high-voltage zokrema, are twisted with a path to measure their support with an ohmmeter. As an accessory, it shows inconsistency - everything is garazd. When 0 or ohm is shown, the part is replaced. As soon as the hour of recalibration of the high-voltage capacitor, the opir becomes 1 MΩ, then, at the new installation, the resistor is charged, and it is attached to the vikoristannya.

Capacitor overhaul.

Transformer Diagnostics

Rechecking is carried out with an ohmmeter, which measures the windings. In the primary, fallow model of a micro-furnace, it can be in the range of 2 - 4.5 Ohm, Opir high-voltage winding can be set to 140 to 350 Ohm. The norm for the filament winding is the range of 3.5 - 8 ohms.

Recalibration and replacement of the magnetron

If the fault is not revealed, and the micro-wave oven is not hot, proceed until the magnetron is checked. For whom they take the upper cover, put the clamps with wires and win the opir between the visnovkas.

Like an ohmmeter showing a sprat Ohm - a thread of tension, in case of inconsistency - it is broken and the magnetron is replaced. If the voltage is intact, but the magnetron does not work, it is necessary to check the correctness of the passing capacitors, re-stuff the arms with it with visnovki and, if necessary, replace the capacitors.

The reason may be the disruption of contact in the soldering areas of their visnovkiv.

To take out a faulty magnetron, take out a transformer and wind it up and turn 4 bolts. To replace the neobov'yazkovo vikoristovuvat such a type, pіdіyde be-yakiy іnshiy (for example, in the micro-furnace Mystery mmw) with similar characteristics in terms of tightness.

Usunennya buzzing

On the back of the head, the buzzing of the buzz is shrugged off. Like a transformer, it will be replaced by a similar one. The right fan sounds good through the system overheating. Shchob vіn zamovk, enough to rearrange the pіch filed in the wall and clean the shovels.

Inspirational wrapping for piddon

For the purpose of identifying the cause of the malfunction, a piddon is known. If the clutch, which is connected to the motor shaft, is not folded, the wire is being checked, which is going to the motor shaft. Possibly, if you see or see a contact, which you need to clean and fix on a large scale.

Guided methods to allow the repair of Whirlpool micro-furnaces, repair of Panasonic, Samsung micro-furnaces, or other ovens. Ale, even though I didn’t realize it - next to marvel at the beginning of the video of the repair. Video follow the principle - marvel and repair.

On the video about how to repair in the home minds of Whirlpool micro-oven ovens:
