There will be a technical sheet hidden behind the controller assembly or elsewhere.

There is a YouTube video here which shows you how to remove the controller assembly in about 5 minutes.

You can also find it online here.

It may be a bad door switch, controller problem, inverter problem, or defective high voltage part.

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

Here are some links you can use for test help, but read the safety warnings first:

http://www.gallawa.com/microtech/cap_test.html (if it is NOT shorted, it's probably fine)
http://www.gallawa.com/microtech/diode.html (if it is NOT shorted, it's probably fine)
http://www.gallawa.com/microtech/mag_test.html
http://www.gallawa.com/microtech/xformer.html

The average DMM doesn't have a high enough voltage to bias a high voltage diode, which is several diodes is series.

If the diode was not shorted, it was probably okay. They almost always short when they go bad.

I don't advise people on measuring a microwave's high voltage. The voltages can be instantly lethal.

The tech sheet should show you how to measure the resistance of the windings of the high voltage transformer. You know you're getting 120V on the primary.

The capacitor is probably okay because they usually short when they fail, and that would blow the fuse when you hit Start.

Look for corrosion or signs of melting on the FA terminal of the magnetron (and on the other temrinal if someone reversed the wires). Look fro a loose connection at the magnetron.

If these connections are fine, then you probably have a bad magnetron.

Probably the best prices on Whirlpool parts can be had here.

SOURCE: Microwave malfunction

Wow. A shocking tale...

It sounds to me like they're guessing ("shotgunning" as it's called) and don't have a clue how a microwave works or how to fix one.

They can't possibly be a Whirlpool-authorized service center can they?!

They apparently replaced two parts that did not fix it, so they should not charge you for those parts, or they should put your old parts back in. What are the odds they would have them still?

If you've not paid them any (or much) money, I would tell them to keep the oven and buy yourself a new one.

If you have paid them anything, I would insist on a full refund and your microwave back with all your original parts (if available).

If you hired someone to paint your house, and they only painted your window panes, should you pay them for the labor or the paint??

But to be honest, I would not trust this shop as far as I could thrown it. If you do get this oven out of the shop, the next servicer may find a whole lot of bad parts all of a sudden... Know what I mean?

If they give you any more trouble, I would go straight to your State Attorney General's Web site and file a complaint with their consumer protection division (or at least threaten the shop with this action).

A State government's Web site is at www.state.xx.us or www.xx.gov where xx is replaced with your Stat's official two-letter abbreviation.

Good luck.

SOURCE: Microwave not heating, unit buzzing, strong ozone type smell

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

With a smell present, I would not suspect the capacitor, but here are some links you or someone you know can use for test help, but read the safety warnings first:

http://www.gallawa.com/microtech/xformer.html

I would most suspect the magnetron or transformer.

SOURCE: microwave runs but does not

Not heating is a problem that can be caused by three things.I'll list the most common solution first, the magnetron that actually does theheating has gone bad. It is possible for you to also have a bad high voltagediode that has opened up, solution two, or solution three is the high voltagecapacitor is not working properly as well. But mostprobably it is your magnetron that is bad. If you are not do it yourselferyou'll need to take it to a repair shop to replace. However, if you know how touse a screwdriver and can unplug a couple of wires with spade terminals onthem, then you can take it off yourself, find another one and replace it thesame way you took it off. The magnetron sits behind the control panel of yourmicrowave but on top. It has cooling fins on it and has 2 terminals maybe threedepending and make and model that plug into it. It has 4 screws that are easyto get to that actually hold it in place. If you do not have a good localsource like an electronic parts supply place then you can find the rightmagnetron at www.mwoparts.com. Be sureyou always unplug the microwave before touching or trying to take the heatcover off and then when you take the magnetron off also. If themicrowave appears to be working normally (i.e.: light comes on; timer countscorrecting, turntable turns) but there is no heating of the food, it could alsobe your high voltage fuse - normally 5kv 700mA or 0.7A. Check and if foundfaulty replace with same specification component.

Hope this will help you. Good Luck.

How CAN i TEST MY MICROWAVE?


Most common cause of an F7 code on these models is a bad inverter or magnetron. Generally it is best to replace both the magnetron and the 1100 watt inverter board at the same time, since a bad magnetron is usually what burns out the inverter board.

I have a Samsung microwave model SMH7177STE/BE. Will only heat a few minutes before and shut off, now there is no heat. I am a licensed elect. but no experience with microwaves and having difficulty...


Its tripping a high limit most likely. Be careful there is 2100 to 4000 volt high side with a capacitor if its not an inverter. The standard components consist of noise board, fuse, touch panel and power controller, high limits, door switches, whipper motor, fan, transformer, capacitor, transformer, magnetron, diode, plate rotator.
Discharge cap (for safety and further testing).. Test fuse; if fuse tests blown test door switches first. Test limits. Check amp draw with slow blow fuse; open door to stop unit and again discharge capacitor. Test resistance to ground on whipper, fan, magnetron, light. Test resistance lead to lead (measurable on motors/coils/magnetron). Test capacitor in ferrads, compare to spec on print. Check diode forward and reverse. Test output voltage from power control board to transformer. Test transformer coils.
Best of luck and play safe; dont test voltage output from the transformer, voltage at capacitor or magnetron.

Whirlpool gh5184xps over-the-counter microwave no power


There is a high voltage fuse in the unit attatched to the high voltage capacitor, it is the most common problem for microwaves not working. Also check the protective diode,the high voltage capacitor as well as the transformer if the fuse is ok. Good Luck.

Whirlpool Gold Accuwave wont heat


Hi, there are three issues that will cause a no heat situation in a microwave. these issue are a failed Magnetron, busted cut-off fuse and, failed diode.

I recommend checking all these area that are located inside the microwave for faults.

The most common issue will be a failed Magnetron.

The diode and, fuse will be located on the noise filter assembly.

We have a whirlpool GH5184XPS-4 microwave that we are getting an F7 error on. We removed control panel and parts of the board were scorched. we resoldered in loose parts still have smae problem


From the technical sheet usually located behind the control panel or grille:

F7 Power to magnetron interrupted

1. Check the door, hinge and cavity front alignment. Adjust as needed.

2. Check the operation of all interlock switches.

3. To check the over-temperature protection for the magnetron, unplug microwave oven or disconnect power.

4. After 40 seconds, check to see whether this solves the problem.

5. If this solves the problem, check the cooling fan for proper operation or blockage.

6. Unplug microwave oven or disconnect power.

7. Check resistance of the magnetron thermostat. It should be close to 0 ohms. If necessary, replace magnetron thermostat.

8. Check that the control cable to the 1100 watt inverter is correctly connected to plug P2 on the display PCB. If necessary, adjust or reconnect.

9. If interlock switches operate correctly, replace 1100W inverter.

10. If problem persists, replace electronic control.

11. Plug in microwave oven or reconnect power.

The most common causes for a lack of heating are a bad door switch, a loose connection on the magnetron, a bad magnetron, bad connection on the control circuit board, a bad relay on the board, bad high voltage diode, or bad high voltage transformer.
