If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron. Check this link to know how a microwave works:

So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off. Check the wave guide covers, if food had deposited
then it must be checked or replaced. See link:

SOURCE: Microwave does not heat/cook

hi

power spikes are very damaging to a microwaves internal parts, it sounds like your transformer and/or magnetron are blown. if the unit is out of warranty I would recommend calling a repairman or getting a new microwave (the transformer & magnetron are expensive and dangerous to work on) also get a small single plug surge protector for the new one.

SOURCE: Jenn-Air JMC7000 Microwave Stopped working

So it's dead? (No display, no inside lights, no beeps?)

A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to open. When it cools, it closes the circuit and allows power through again.

If it's random, it may be a bad connection, usually on the control board or fuse holder.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.

SOURCE: Microwave won't heat food.

My Whirlpool microwave, over the stove, stopped working when my son used it to heat his food and a heavy sound came out, like something exploded in it. When I check it, there was nothing broke. Everything works fine except that it does not heat. I will appreciate any help

Ihave a Jenn-Air JMV8196 microwave oven. The clock works,the fan works and the light works. Not sure why the microwave will not come on to cook. Help?


The problem is caused by one of three things, the magnetron "heats food" the high voltage diode "sometimes shorts" or the high voltage capacitor " shorts"

I have jenn-air microwave oven model m167. Unit will come on and all programming works to heat food. Oven acts as if it is heating food,however it does not cook or heat food items. Any help with...


It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

Jenn Air Microwave Error Code


Hello Hec1152,
I have found the manufacturer contact information for you, but could not find information about the error code. If everything works fine, but the microwave is not heating your food, then the problem is most likely the magnatron or one of it's components, which sadly to say is the most expensive part to replace. Please feel free to contact the manufacturer via phone or live chat to get more details as to what the error code means.

If you would not mind, could you please rate my help. I would greatly appreciate it.

I always recommend that folks use the vent / hood fan anytime they're cooking with the stove.

Was it on at the time?

If not, moisture can certainly get into the works and cause problems or damage. If it dries out, it's fine but if not, it could cause damage.

We're happy to help and we appreciate your thoughtful rating of our answer.

Jenn-Air Microwave turntable not working, microwave works


It's probably a cracked coupler or a weak, slipping motor.
