Ge spacemaker xl 1800 - no heat

The magnetron tube may have died. Not worth repairing unless under warranty.

My guess is the magnetron is bad. It is rarely the transformer

Suspect inverter (power) and or the Magnatron---neither are cheap parts.

your heating element went bad.

It sounds like the main transformer has failed. It would be cheaper to replace the whole microwave than repair this one. Sorry to be the bearer of bad news. Hope this helps. Good luck.

I have a GE Profile Spacemaker model JVM3670WF001, purchased I think in 2003. Pop sound, no Heat. Light goes on, carousel goes around,
Repair or new microwave

Possible bad heating element, You should remove the cover of the unit and look at the heating element with the power off. Until you get your problem resolved I would recommend not to even turn it on due to the fact that you are unsure what is going on and you smelt some burnt smell. Just for safety until you fine the problem
