Last week while cooking something on high for 12 minutes the microwave *died* at the end. No power, no lights...dead. I unplugged it when I noticed it felt very warm. The next day I plugged it back in and it reset, but now it makes a rattling/whining noise and still gets very warm so we are afraid to use it.
Does it need a new filter? Something more? Why is it whining?
What could it be?
Thanks
Ge spacemaker XL1800 (JVM 1870BF02) doesn't heat, lights, turntable works.
Typical diode used in microwaves---it should not read shorted from one end to the other.
Typical Magnetron--can look fine and not a real way except by replacing to know if good or bad.2,722 views

IT IS DEAD, NO TURNING ON ANYMORE
The magnetron probably overheated and caused
the magnetron thermostat to open. Then when it cooled, it
closed the circuit and allowed power through again.
You first need to make sure that your internal cooling fan is running.
When I say internal
cooling fan, I do not mean the hood vent exhaust fan which you can turn
on and off manually.
I'm instead talking
about the internal fan which comes on automatically whenever you
microwave.
We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.
It is vital that the
cooling fan runs, or the magnetron will be destroyed.
In some cases, the cooling fan's blade will become loose on the motor shaft so that even though the motor is running, the fan is not blowing.
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.
Once you look this over, let us know what you find and we'll take it form there.
