You might have a bad door switch, open thermal protector, or the latch mechanism is not activating the switches properly.

SOURCE: Microwave Turn Table

This could be a failing turntable motor, but more likely your turntable support has gotten bent. That's an easier and cheaper problem to solve. Excessive heat can sometimes make the legs of the support bend so that the center is raised up far enough that it won't always make good contact with the motor. You can test this by running the microwave empty for a few seconds. It may hesitate to turn or stutter. Next try it with a bowl with several cups of water in it. The extra weight may push it down so it makes good contact and runs without a hitch. The way I fix these is to use a stove burner or a torch to heat up the legs and bend them up a bit. Then I quickly set up or clamp the support so it's held in the proper position for a few minutes until it cools. One way to hold the heated support in position is to place an object under the end of each leg and put something slightly heavy on top of it in the middle. If you need a new motor or just want to see helpful exploded views of your model, see the GE or Sears parts Web site: http://www.geappliances.com/shop/prts/ http://www3.sears.com/

SOURCE: display panel works but no heat, no fan, turn table doesn't turn

This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

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 or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

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

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, 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.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases in about a week or so.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

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.

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.

SOURCE: microwave lights up but does not heat or turn

Check your door interlock switch. Unplug the device, remove the cover DO NOT TOUCH THE SILVER CAN - POTENTIALLY LETHAL. Locate the small, probably black micro switch. Test it with a volt/ohm meter or other contunity tester. It should read "closed" when the door is closed and "open" when the door is open.

If you are like me, you turn the machine off by opening the door. When you do this, power sparks between the small contacts in the micro switch and eventually burns them up. When this happens, the machine thinks the door is open and will not turn on the magnatron - thus - no heat.

Find a replacement switch at a electronics or appliance parts place. You may have to provide make and model for an exact replacement. If you are handy, you can adapt any regular micro switch.

Let me know if this works for you.

Microwave will light up an looks like it is working but no noise exhuast is not blowing but does not heat food. exhuastfan does work when button is pushed?


Microwaves have a very simple mechanism but with some interesting parts. The most complex part of the microwave is the Magnet-tron. The magnet-tron is the part that does all the job in conjunction with a high voltage transformer. Both of these units would need to work properly for the elements to heat up in the microwave. Now, put a glas of water in the microwave if it does heat up the water to a minimum then the magnet-tron is faulty. If the water does not heat up then the magnet-tron is faulty or the transformer. These are the commune parts in the microwave that fails. There are other peripherals that could be faulty such as the capacitor, the high voltage diode that is connect with the capacitor. Some times the problem is very simple where just a switch is the one not doing it. For example the switch that close the door is not connecting properly also one of the thermostat is open permanently.

Microwave lights up doesn't turn on


The part of the oven called the "magnetron" (this part is what creates/generates the microwave energy that heats the food or liquid) is burned out, the cost to repair is more this part is more than the cost to replace with the cost of Microwaves so depressed by the stagnant economy.

My GE Microwave, model # JE1640WA001, stopped microwaving. The timer works and the light inside the microwave turns on, but now the turntable and the fan do not work. Sounds like a relay is kicking in as...


Is the unit heating the food? If not you may have a fubar magnetron tube. But it is fused so you might want to check the internal fuse to make sure it is not open.

This is not safe. If the fan is not running, the magnetron will quickly overheat and be destroyed. We answered this in more depth in the other place you asked it.

GE Microwave JVM1441BH04: Safe to reconnect replacement stirrer & turntable motors after accidentally burning out the turntable motor? GE JVM1441BH04 Over Stove Microwave: Tapping noise was coming from the 21v AC stirrer motor which sits atop the cooking chamber. I disconnected the two connecting leads, unfastened the single screw holding it on, placed in on my scanner glass to get a high rez photo of all the specifics listed on the motor label. Bad news: While waiting for the scan to finish, I warmed my coffee in the microwave on the highest heat for 30 seconds. I subsequently discovered the 21v AC turntable motor, which had been working just fine, was now no longer working, with infinite resistance across its terminals, and a burnt electrical smell. Both the stirrer and turntable motors are powered by a 24v tap off the magnetron fan. My theory: By running the microwave with the stirrer motor out of the circuit, I delivered excessive voltage to the turntable motor, which quickly fried. The 24v tap off the magnetron fan motor currently shows the correct 24v output. However, with both the stirrer motor and turntable motor disconnected, running the microwave for a few seconds shows approx 95v across the wire leads for both of the 21v motors. I have obtained replacement motors for both the noisy stirrer motor and the fried turntable motor. My question: Can I simply reconnect both motors in their proper locations, vow never again to run one without the other connected, and all will be well? Or will the newly installed motors simply be fried in a matter of seconds?
