Mst likely a blown fuse. You''ll need to unplug the unit, remove the outside cover and follow the line cord and you should find the fuse.

Replace it with the EXACT same value that was labeled on the original fuse. You'll probably be able to find a replacement at any Radio Shack store or hardware store.

Replace the cover and plug the unit back in. Hopefully nothing was damaged and the unit will play again.

Please let me know if I can be of further assistance to you.

Good luck!

Had a small fire in the microwave and the power went out. Power is on to the receptacle, but there is no power in the unit. Is there a circuit breaker in the unit or is it toast?


Jim, a lot of microwaves have internal fuse, question is do you really want to bother after it has been on fire. Just a thought.
Good Luck.

Door will not open 1999 model


The unit needs to be shut down by cutting power to the oven by either pulling the 110VAC plug from the receptacle or flipping the toggle on the house circuit breakers.

Whirlpool microwave gh7208xrb-3 fuse is good but the unit has no powernothing lights up at all it like it is dead.


Control board might be dead. Cost is quite high could run up to $200 or more. Many times I recommend just to replace it. Here's the dumb question, is power present at receptacle?, if over range microwave, in cabinet above microwave? Check for gfci receptacle tripped. Sometimes fuses appear good, always be sure to test with a meter.

GE Microwave Model JES1651SJ-02, Serial 902410. Unit appeared to be fine yesterday evening with the clock working properly but this morning it shows no lights and keypad is not operational. Checked both...


There will be a fuse, magnetron thermostat / thermal cutout, and an oven cavity thermostat / thermal cutout.

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.


At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

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

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Remove unit and check trip/reset switch on unit. Double check GFCI receptacle with plug tester with GFCI test button.

Microwave shut off like it lost power but the receptacle does have power to it. My model is an LVM1750.


The thermal cut out switch in the cavity is bad. I was unable to locate a wiring diagram on the internet but when I took the microwave apart, I found the wiring diagram inside the microwave on the back side of the touch panel.

This unit is mounted above the stove. We were cooking on the stove and also in the microwave. I think there was enough heat to trip the TCO switch.
