Generally the magnetron (the part that heats the food) is the cause if everything else still works. Unfortunately replacing the magnetron is barely cheaper than buying a new microwave though you can check out repairclinic.com to decide whether you want to attempt replacing the part.

Let me know how this works out for you.

Assuming the turntable works maybe your magnetron isn't working properly. Cheaper to buy new microwave then to fix it.

sounds like the magnatron has gone out

Probally the belt is broken on fan up at the top.

I have a GE Spacemaker Microwave, model # JVM1650WB008

The lights work and everything runs in a normal operation, it will not heat the food. I have changed the fuse and still the same, no heat.
