SOURCE: fuse keeps blowing.

couple questions -
what else is on the circuit,
and what current does the oven need

there are whirlpool over-range models with
1200watts of microwave,
1500watts of convection power, a
60watt bulb and a
375watt fan

over 15amps -20amp circuit needed

if you inadvertantly replaced a higher current fuse with a 15amp fuse, it will blow every time.
the install guide http://www.whirlpool.com/assets/pdfs/product/ZINSTALL/8206589.pdf reccommends 20amp
not a solution, something to check,

SOURCE: Microwave won't heat, and turntable doesn't turn

All the parts you mention are very inexpensive, but yours does not have a triac.

It could be the cook relay, but it's more likely to be a switch.

Looking at the schematic, it's probably a bad primary interlock (upper door switch) or maybe its mount is bad.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you have a broken mount, it's usually more economical and safer to just add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

There may also be a "mini-manual" hidden inside the unit behind the control panel or elsewhere, which is very helpful when troubleshooting & testing.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you only need a switch, you can order a universal type here for $5 postpaid.

SOURCE: GE Microwave JE2160 does not heat

Does it make any noises that it didn't before it failed?? It could be a bad secondary interlock switch, cook relay on the PCB, HV circuit problem or bad magnetron. You need an ohm meter to troubleshoot. If you take the cover off, you MUST short across the High Voltage Capacitor terminals to discharge any possible residual charge to prevent shock hazard.

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.

Oven suddenly lost heat, inside fuse is OK though. Display, fan, turntable all working. Is it magnetron or its power supply?


You're right, if the lights come on and turntable moves, it is most likely your magnetron.

Microwave doesn't heat.


HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

Whirlpool Microwave no longer heating


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.
