It sounds like two separate problems.

1. It sounds like your magnetron is overheating and then the thermostat trips, cutting the power until it turns off, then it closes to power it back up.

It's essential that the internal cooling fan (I don't mean the hood / vent / exhaust fan) is running to be sure the magnetron stays cool.

2. It also sounds like your vent / hood / exhaust thermostat is sticking or the triac on the circuit board is leaky, causing the vent fan to stay on.

But you may want to check the owner's manual. It is designed to stay on if the temperature of the stove top is above a certain level.

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.

We have a GE Profile Spacemaker XL 1800. It began making a laboring noise and stopped cooking at the same time.


Sounds like the Magnatron or the HV Cap or diode is failed. Process of will show you which one. Very dangerous area to work in, not for the untrained. Eric

Spacemaker XL1800 runs but doesn't heat.


I think you should check the fuse first that runs the magnatron if the fuse is good that means the magnatron is bad! but if its only the fuse then you save time and money!

Assuming that your internal cooling fan is working, I would suspect that your magnetron is failing.

You can usually 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, and locating components.

I would check the cooling fan, then suspect the magnetron.

Microwave oven does not heat anything. Clock, turntable, lights work. I turned the turntable off while the oven was cooking--heard a noise, now it doesn't heat anything.


Spacemaker XL 1400 worked for 7 years.Yesterday, no more heat. Also plastic door damaged.
will try Panasonic or something commercial
