IT'S THE MAGNITRON - CHEAPER TO BUY NEW THAN REPLACE - SORRY.

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.

Generally the magnetron (the part that heats the food) is the cause if everything else still works. Unfortunately replacing the magnetron is barely cheaper than buying a new microwave though you can check out repairclinic.com to decide whether you want to attempt replacing the part.

Let me know how this works out for you.

Please check the door switch for proper operation.

if everything works except the heating, it is most likely the mag tube is on its way out.........that is the most common reason for it not too cook.......since the microwave is a GE and it is 3.5 years old, i would say you are better off buying a new microwave, the mag tube starts at around $70.00 and up + the labor it costs too have a service person put it in........around another $60.00

sounds like the magnatron they can just go out like a light bulb easier to buy a new microwave hope this helps regards Jim

Sounds like the magnetron has failed. It is the magnetron that generates the microwaves that heat the food. If it or the circuit that powers it fails then it stops heating. There are some high voltage circuits that feed the magnetron and you can potentially get hurt if you don't know what you are doing. Would recommend you have it serviced by a professional if you want it fixed, otherwise look for a new one since the cost of repair can come close to the price of a new microwave oven.

Generally, you get something unless the fuse inside is blown. There is generally a fuse inside the unit when you remove the button package. First, make sure that the outlet you have is good. Plug something else into it and see that it works.
