I was using my microwave to heat something while it was cooking the microwave stopped working and the fan turned on. We can't turn the fan off or turn the microwave on. Don't know what happened. MFG July 1994; Model # MQ1000W. It is a Quasar Superwave microwave/convection oven. PLEASE HELP.

The word COOL is displayed when the microwave goes into a cooling cycle. The cool cycle is a feature that ensures the operating components of the microwave (Inverter and Magnetron) are cooled after operation by running the fan inside the microwave.
The cooling function is activated whenever the microwave runs for over 3 minutes or is operated twice within a 10 minute period. The word COOL is displayed to tell you why the fan is still running. You do not have to wait for the cool cycle to complete before using the microwave again, simply enter the cooking operation you wish to perform and the cool cycle will stop and the microwave will perform the cooking operation you have just entered.

We are very sorry to hear this and we apologize for the inconvenience this has caused you. We would be glad to look into this if you could email us at [email protected] with your name, address, phone number and the model & serial numbers of the Microwave.

your magnetron might be out. its what heats

The heat sensor in the electronics panel senses the rise in heat from the stove below. Once the amount of heat reaches a certain level, the cooling fan turns on to keep the electronics inside the microwave cooled.

I wouldn't worry about it. mine does the same thing.

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

Sounds like a classic bad door switch or switch holder. If you or a friend decide to work on it, we have *critical* safety info, info on door switch testing and replacement, and oven disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your base model number (without the suffix) here: http://tinyurl.com/gv383

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

From looking at the owner's manual, it looks like the vent fan is only supposed to come on when the internal temperature of the microwave gets too high OR when you press the VENT FAN pad. Here are a couple of fan-related excerpts from the owner's manual, which can be found here: http://products.geappliances.com/ProdContent/Dispatcher?REQUEST=SKUOBJECTS&DOCUMENT=Use%20and%20Care%20Manual&SKU=JVM1840BD (or the better URL here: http://tinyurl.com/yn7r6g) Automatic Fan An automatic fan feature protects the microwave from too much heat rising from the cooktop below it. It automatically turns on if it senses too much heat. If you have turned the fan on, you may find that you cannot turn it off. The fan will automatically turn off when the internal parts are cool. It may stay on for 30 minutes or more after the cooktop and microwave controls are turned off. - Vent Fan The vent fan removes steam and other vapors from surface cooking. Press VENT FAN once for high fan speed, twice for medium fan speed, a third time for low faw speed, or a fourth time to turn the fan off. Press the VENT FAN BOOST pad for extra fan speed. - Hope this helps.
