Question about Whirlpool MH7140XF Microwave Oven

1 Answer

Small fire in above range microwave, now completely dead.

I made a handwarmer with ceramic cooking beads & corduroy. I was warming it per the instructions & it caught fire. Now the microwave isn't working at all... the panel lights are out, the inner light is out, it doesn't beep when buttons are touched. It was a small fire, there is no melting or physical damage that we can see (other then it really smells smokey) It is a Whirlpool MH7140XFQ I was wondering if there is a fuse box I can check before we replace this... Thank you in advance for your help.

It probably put too much heat in the "innards" of the microwave and probably opened the thermostat or thermal fuse located inside -either on the chassis of the microwave or or the magnetron. If you or a friend is handy and wants to check and replace it, it's not a hard job as long as you play it safe. It will look something like the attached photo. In my profile you can find a link to my site where you can find critical safety & disassembly tips. There will be numbers on the side indicating the temperature and you can take the old one to a local appliance parts store to get a new one. NOTE: The one for the hood fan will read open at room temperature, so don't confuse it with the other two thermostats, which will read closed at room temperature. Post back if you need more help.

Cannot turn microwave off. Help

Only happens when cooking a big pot under the microwave? Hosing thermal fuse / thermostat kicks in to cool the microwave. Is the micro. Installed proper height above the range? Are you using the fan when cooking on the range?

Samsung over the range microwave oven model# SMK9175ST the microwave part stopped heating

If "everything" works and your microwave just stopped heating, the problem might be with the internal door switches, the high voltage circuitry, or the circuit board or quite probalby your magnetron is dead. If you don't have the technical knowledge to repair microwaves, you should take it to a repair service for diagnostics.

Over cooked noodles ,food caught fire, no visible external damage,some smoke black, but control panel dead completely.What can i do ?

Probably the main fuse has blown. If there is damage to the inside of the microwave I would seek professional service to ensure that seals are still working.

Microwave suddenly went dead - completely black. All 'house' fuses are okay. Could it be a fuse in the microwave itself?

Yes! that is exactly the problem, the fuse is a ceramic type "white body with silver ends" located near the high voltage capacitor, unplug and allow 30 seconds for the capacitor to dis-charge before removing the fuse. Keep in mind the reason for the fuse to blow is often caused a defective door switch, or you just might get away with changing the fuse.

Door-activated power switch is loose and/or has a short

Fixed this problem! The door latches were greasy and sticking in the closed position (i.e., pushed down so not latching and engaging fully when the door was closed) and this created the problems described above. Solution was to squirt some Windex into the latch holes to dissolve the grease. The switches popped back into position (must be spring-loaded) and the door closed and latched properly, allowing the oven to function properly. I swabbed out the hole with a q-tip, let it dry for 20 minutes and all is well.

GE Over the Range Microwave/Convection won't start

So it's dead - that is to say no display, no lights, and no response from the keypad?

A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to open. When it cools, it closes the circuit and allows power through again.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.

If you or a friend decide to look into it, we have critical safety information and disassembly information at our site, linked here on Fixya:

Whirlpool microwave/oven model RM286PXV3

Just so I understand, you replaced the fuse inside the oven? If so, I would suspect a bad thermostat attached to the magnetron. This device interrupts power when the unit gets too hot. I've included a representative photo. After so many years your magnetron may be bad, too. Once you get the oven working, if it cooks and doesn't trip the thermostat again, it may be okay. PLUS - It looks like this model has manual rotary controls. If so, it's common for those to develop bad contacts after so many years. I would consider that my third suspect. Those controls are called the thermostat (not to be confused with other part by that name that I discussed above) and the selector switch. One could easily be bad. You can check part prices at Sears online at (the "3" is supposed to be there) Some other things that can cause a "dead" condition: - bad connections on the small circuit board where the fuse is mounted (if such a board is present) - bad connections in the wiring Good luck.
