Sounds like you either have a door switch that's not being activated, or is defective. Check the secondary (usually lower) switch first.

Another possibility could be a defective thermal cutout on the oven cavity.

I just read that starting the microwave as usual and then slightly pressing in the handle (you can hear the heater(?) come on will make the heat come on. Tried it and it works. My repairman told me it needed a new magnetron ($700) but that was totally wrong. I will be trying another repairman to replace handle mechanism.

My kitchenaid microwave will not heat in microwave mode. In fact the turntable starts and stops and the display blinks intermittenly. In convection oven mode everything works fine - It heats, turntabl


The magnetron is the main part that gives out microwaves to heat the food. As the convection bit is working this points towards the microwave bits.
The magnetron has a main diode, fuse and transformer to run the microwave bit, any of these could be faulty. A word of warning though, there are extremely high voltages inside microwaves, even when unplugged in the main capacitor. Also to repair this section you will need to be a fully qualified engineer to even order parts for this.

Most likely you have a magnetron problem. Easy to replace (DYI) but make sure the high voltage capacitor is fully discharged first against the case.

Microve turns on, but will not heat Model number is FMT148G1B2 Everything seems to work except there's no heat. Clock works, countdown timer, light, turntable, etc., just no heat.


Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

Check the door switch, when it is faulty the oven will turn on but turntable, fan and magnetron wont operate.

Regarding parts, contact the seller here to purchase parts.

You can also order from MicrowaveSvc , they also provide parts.

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

G.E. Profile Spacemaker XL1400 will not heat food


This can be the magnetron power supply area, the controler for the magnetron power supply, or the main control board itself.

If the turntable is spinning, the countdown timer is working, and the fans are going, this leaves out the possiblity for a defective safety switch.

I suggest you send the microwave oven out for an estimate if it is out of warranty. I would not suggest you try to fix this yourself.

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

Panasonic Microwave NN-A770S getting hot on right side externally


If you described this to Panasonic very carefully, and they said it's normal, then I would say keep using it until such time that you get other symptoms. The inverter has some parts mounted on a large chunk of aluminum called a heat sink. It draws the heat out of the parts and the heat radiates and/or convects away. This keeps the circuit parts from overheating. As long as you have good air flow through the vents, it sounds okay.
