SOURCE: Will not heat.

Hi I've been out of the microwave repair business for a few years now, but the technology has remained virtually the same as far as I know. You obviously have some knowledge of them, as you know about the safety switches in the door. Microwave ovens are actually a very simple device, to test it, put a coffee cup of water inside, and set the unit on high for one minute. A second or two after you hit the start button, you should hear a fairly loud "bong" noise, and a hum that continues untill the time runs out. That noise is the magnetron starting up, and if that noise does not happen, then the magnetron or related circuitry is probably bad. NEVER open up the oven, as the magnetron may be charged, and must be discharged by a technician. If the sounds that I described are present, then the water should be boiling or close to it in one minute, if not,then something I've never seen has gone wrong. Assuming you had a year warranty on it, I know from experience that if you contact Goldstar customer service by phone, or letter, they will often extend their warranty a month or so to keep happy customers. Its worth a try. Hope this helps you out. P.S. Never operate a microwave without something inside (Non metalic)

est the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.

Thediode and capacitors can br tested. The capacitor must bealloweddischarge before testing, or you risk to get electrocuted, evenifpower is off. Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

Coleman EB15A - Buzzing noise from transformer area, no heat or fan


see this causes and proceed. God bless you
Magnetron If the microwave is loud or noisy only when cooking, the magnetron tube might be defective. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. Under normal circumstances the magnetron is nearly silent. However if it is damaged or nearly burned out it can begin emitting high pitched or growling noises. It's not normally dangerous to use a microwave oven when it makes these noises, but they are an indication that the magnetron is almost dead and will need to be replaced.

Exhaust Fan Motor If the microwave is loud when running the fan motor might be
Stirrer Motor If the microwave is loud or noisy the stirrer motor might be worn out. The stirrer is a metal blade which slowly turns around, deflecting the microwave energy in a random pattern inside the microwave oven. As the motor nears the end of its useful life it begins to make grinding noises. The microwave will not heat food evenly without this stirrer, the motor should be replaced.

Turntable Motor If the microwave is loud or noisy the turntable motor might be worn out. This is a common problem and relatively easy to replace.

MY MICROWAVE DOESNT HEAT UP FOOD JUST COOKS


Hi.

The wave emitting part inside the microwave oven is called the magnetron. The waves emitted by the magnetron generate heat in food. When the microwave is running, turntable turns and light comes on but there is no heat it means that either the magnetron is faulty or the magnetron is not getting power. When the magnetron is not getting power parts such as the high voltage diode or capacitor must be tested or replaced. Testing and repair must be carried by a technician. Here some general troubleshooting: http://www.fixya.com/support/r2096491-microwave_works_normally_but_not_heat

Buzzing sound... Turntable stopped. food heats up but uneven. No microwave fan when heating.. no light inside expensive fix?? Unit is 10 years old


If the microwave oven is 10 years old then it is time to consider a new unit, by your description it is going into cascade failure where different parts have stopped working, the buzzing sound is the magnetron warning you, it is about to fail. The fans job is to keep the magnetron cool while it is running.

Microwave runs, turntable turns, fan runs, but does not heat,


No heat means the magnetron circuit has failed. It is the part that generates the microwaves to heat the food. Usually not worth fixing since the magnetron costs nearly as much as a new oven. To diagnose, if the oven is on, you will hear a loud buzzing sound if the magnetron is shorted.

THeood is not getting heated and the turntable is


the unit inside the microwave that heats called the "magnetron" has gone bad or the circuits that power the magnetron and turntable have failed. if its under warranty still, send it back to the manufacturer. if not you can call some repair shops and see how much it would be to service it, but its most likely going to be cheaper to purchace a new microwave since they are relatively cheap these days, and electronics repair people are not cheap. hope this helps

If all appears to be running as its working but just no heat. Could be issue with magnetron. You could also have loose connections to magnetron or somewhere in high voltaged as well.

MIcrowave light and turntable are working, but food comes out cold


I suspect the magnetron or high voltage transformer, and either part's cost or labor would probably be about the same as the cost of a new comparable unit.
