Recently cleaned inside of microwave, now not heating

There is a small sensor in the micro wave that controls the heat. You probably got water on the connections and shorted it out.

HELLO.

The first wayout is to consider WARRANTY.If the microwave is under warranty return it to the point of purchase to enjoy warranty right.But if the microwave is not under warranty another wayout is needed.

Below is the solution on how to make our microwave heat food.

1 Remove oven racks and place them in soapy water to soak.

2 Preheat oven to 200 degrees.

3 Turn the oven off and spray the inside with oven cleaner.

4 Allow to sit for 10 minutes.

5 Wipe the cleaner and dirt away with a damp sponge, rinsing frequently.

6 Dry with a soft cloth.

Thanks.

The most likely cause is a bad magnetron, "heats food" the other two possibilities are the high voltage capacitor and diode. The cost to repair will a approach a new microwave oven.

could be the capacitor but also could be the magnetron which is a common problem with heating and one of the main sources of heating.... everything will work with a bad magnetron also it just will not heat... common problem with these... to test the capacitor you will need a meter that test microfarads or mfd good luck to you ....

Did anything spill or blowup inside? Remove the glass tray and be sure all is clean and dry.
If something did blow up (food or liquid), find the small mica window on the inside, and carefully remove it, clean up, dry off in the cavity too, and replace it.
Try to use. This has fixed 3 different microwaves for me. Hope it helps you.

Microwave Oven Basic Troubleshooting Tips

its very unlikley to be the wireless router,,,
things like this just happen,,,i would say the magnatron had gust given up the ghost, thats the part that gets the food hot,,,safest bet is have it looked at but get ready to buy a new unit as its likley to be the cheepest way out
please dont go poking about inside your microwave,,
it will still have 1000's of volts inside it,,, these volts will kill you if you tuch the wrong part,,be warned!!!

If the microwave oven appears to be working but it is not heating the food, it is very possible that the magnetron, or its power supply has failed.

I have the same unit and age the JMC7000 everything appeared normal on the display and countdown etc...But it would not heat,I trouble shooted the problem and discovered it was a faulty door switch I replaced it and it works like new again.I ordered the part from www.repairclinic.com it's an easy fix.and costs a few bucks...

If all controls on the panel work fine but the microwave does not heat, then either you have a defective door switch,the smartboard is defective, or you have a defective magnatron.Most likely one of those three.
