The food never even warms.
My Spacemaker GE microwave seems to be functioning well, i.e. the lights work, the timer works, and the turntable rotates.
I tried a soft reboot and a hard reboot, after which I was able to reset the clock. The only thing that does not seem to function is: the food never even warms. I am trying to decide if it is time to try to replace the fuse, call an electrician, or replace the appliance, It is 12 years old, and has had no problems until this morning. Thanks for your input!
