No power to microwave

Take off the cover to expose the fuse holders. one of them is bad.

Then replace a thermal cutoff

It could be either the inverter (power supply) or the Magnatron itself--both are over 100 dollar parts each.

Hello there and thank you for choosing fixya
Yes it could certainly be the fuse and that is where i would first check and if it checks out good than you may have a fried controle board or even fried wires inside the microwave
You may even have a bad power inverter also ok
Sometimes the boards can be more expensive than the unit costs you originally so be wise to this ok
keep me posted on what you have found
best regards Mike

The description you provide indicates the magnetron has failed, "heats food" and blown the main fuse in the microwave oven, since the unit is 10 years old it is much cheaper to replace with a new one rather than have it repaired.

Hold down the "START" button for 5 seconds.

Most of does have fuse on them.If you will look somewhere around the back of oven where the power cord come in.Most of them have a ceramic fuse.20 amp.

press Reset, then enter in the time of day (e.g. 0807 for 8:07 am or pm doesn't matter), then press Clock button twice. hope this helps.

what is the model number of your radarange? it should be found inside the microwave on the rim.
