Yes , that is how it works. fan cools the magnetron so it run the same time it is heating. you have to look at the fan why it is very noisy, it could have been touching some wires or the bushings may need lubrication. you have to bring it down again, remove the fan and bench test it . lubricate the bushings if necessary.

Microwave made a loud grinding noise while heating a cup of coffee for 1 minute,now everything is shut off. We checked the curcit breakers all ok, and there is power going to it!


see this causes and fix it. God bless you
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.
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.

Exhaust Fan Motor If the microwave is loud when running the fan motor might be

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.

GE Spacesaver Microwave not heating, inside fan not working


I suggest you have the microwave oven replaced, the prices have dropped considerably for the last several years and you have got your money worth out of the unit.

Fan is loud and almost sounds stuck and the food does not heat at all. Now it died all together. No lights on. Is it worth fixing?


From your the description the magnetron has failed, "heats food" the exhaust fan has seized which keeps the magnetron cool when running, and finally the main fuse has opened, It is far cheaper to replace the microwave oven than repairing it.

We were using the microwave the other night and it started making a loud noise like the fan was running (although the fan was not). We let it sit for awhile and try to use it again but the noise came...


The loud noise and no heat means that the magnetron has failed. It the part that generates the microwaves that heat the food. When it fails it shorts out, causing the transformer to heat up. That is what was causing the burning smell. The cost of a replacement magnetron is around $130-150 range so it may not make sense to have it fixed.

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.

Whirlpool MH1150XMB-0 runs but does not heat food


If the housing of the unit isn't too difficult to remove (normally 3-5 Phillips screws around the rear edge), with the unit unplugged of course, check for a user replaceable fuse inside. The magnetron is separately fused and fuses can fail due to metal fatigue. It will be high amperage; 10-20 amperes and many hardware stores will have them. BTW, there is no residual radiation from a magnetron that isn't operating.

Loud buzzing noise with Whirpool microwave oven when it comes on. All lights, heating and fan seems to work but not sure why loud buzzing. What is the problem?


The loud buzzing you hear is the sound of the magnatron tube.That is what emits the microwave radiation and buzzing should be normal. The mag tube may be nearing its end at witch time you will hear no buzzing and hence no heating of foods. Replacement can be costly depending on the model so most people just opt for a new one. Hope this helps
