This sounds like either a capacitor, transformer, or magnatron. Mags unually don't go bad. Either one can go bad and blow a fuse or other safety device. If one shorts, it could burn a section of the circuit board.

I would think about calling a tech and have him diagnose the problem. Tell him you can't fix it now but will in a month or two. Have him write down the things you need so when you do want it fixed, you do not have to start all over again. Then order the parts and fix yourself.

Micro waves can be dangerous and cause burns, so if you think this is not for you, go buy a new one.

Microwave timer works but will motor will not run/cook.


If everything works on the unit, but you do not receive any heat or possibly the turntable does not turn you have a faulty magnetron (controls heat) and a faulty motor (controls turntable). You would require service on the unit, if parts are available. Some microwaves are so small in cubic foot size, that manufacturer's do not have parts available for purchase/repairs.

The fact that the microwave and convection both do not heat indicated that the oven is in demo mode, check the user manual, otherwise it will possibly be a relay not triggering, may need a pcb replacement, check Demo mode 1st....Phil

Everything works except the cooking part/no heating/turntable not turning, help!


you may have gotten a power surge and that can cause some funny things to happen, 1st is there power to the oven, 2nd if so there may be an internal fuse protector built in to the oven, check with the manual for anything of that sort listed. if not you may have to take it in and have it repaired by a pro. there is a lot of voltage in these ovens and unless you know what you are doing a person could get hurt

Won't heat


Do the inside light and turntable come on when you try to cook?

Is it making any unusual noise or is it louder or quieter than normal?

Do you have the model number?

Microwave turns on, but no heat or turntable movement


The problem is that the magnatron is not getting power. Chance is that if could be a bolwn fuse inside the unit. If the fuse don't fix it then that leaves the charging diode, capacitor or the magnatron, or high voltage xformer of which without technical epertize I would not recomend attempting to replace. good luck

Everything works...Except for actually heating the food


It has a bad magnetron. This is the tube that provides the microwaves to heat the food. Not too easy to replace yourself but it can be done. Cost of magnetron is probably less than $50 or $60.
