One day the unit was working fine. The next day, no heat. It runs through the cycle and appears to be working, turntable turning, seconds counting down, lights on, making the normal sounds - but the food is still cold at the end of the cycle. I read through all the solutions to see if I could solve it that way. I have tried pressing down on the door while running but this did not help so I doubt it's a door switch. I installed the unit myself when I bought it in 2002, and I have been an amateur radio operator for many years so I feel capable of doing any repairs safely.
I'm thinking I may have one of the magnetrons from the bad batch I hear GE got one time, or something else in the high voltage circuit is causing the trouble.
Thanks for your help!

Re: No Heat - everything else works
It's most likely a defective magnetron or a bad connection at the magnetron terminal.
The GE bulletin on the magnetron kit can be found here to see if yours is one affected:
You may have a loose and tarnished connection at the FA terminal of the magnetron.
If so, it needs to be disconnected, tightened, maybe burnished or sanded, and reinstalled. If it still won't work, the mag is bad.

If everything works on the unit, but you do not receive any heat or possibly the turntable does not turn you have a faulty magnetron (controls heat) and a faulty motor (controls turntable). You would require service on the unit, if parts are available. Some microwaves are so small in cubic foot size, that manufacturer's do not have parts available for purchase/repairs.
Hi, one of the most common reasons why the turntable won't rotate is that the microwave isn't clean. The turntable guide and carousel can get sticky, preventing the turntable from properly moving. If you have built-on food particles or liquids, fill a bowl with 2 or 3 cups of water and 1 tsp. of liquid detergent and lemon. Run the microwave for about 3 minutes. Clean the microwave with a cloth, including the base of the turntable, guide, carousel grooves and microwave base. Your microwave turntable won't rotate if the grooves on the base of the turntable do not sit right on the carousel. Also, check the position of the turntable guide. Place the guide directly under the turntable. Remove the turntable, and then reposition it into the carousel grooves.
The carousel motor is located beneath the base plate of the microwave. If the carousel isn't turning at all, check the motor. Disconnect the microwave from the power source, and remove the turntable, guide and base plate. Try turning the motor to see if it's just stuck. If it doesn't turn freely after a few seconds, examine the motor to see if it's burned out or corroded. Use an ohmmeter to see if the motor has continuity. If not, you must replace the motor.
The drive bushings are plastic components that sit underneath the cooking plate. Remove the plate, and examine the bushings. Use a magnifying glass if necessary to see if any debris is caught in the plastic. Clean the bushings, and reinsert the plate. Turn the microwave on to see if it rotates. If the bushings are extremely worn or if some of the plastic is broken off, you need to replace it, which is a complicated repair for consumers. Contact a service technician for assistance.
check contact points for current. tabs might be bent and are not contacting correctly and no heat the Ni-Chrome wire heats up glow orange when currant is applied , might need a test voltage Meter and screw driver too >^.^<
Intermittent operation can be caused by a door interlock micro switch, a weak capacitor, an intermittent wiring connection from heat or poor connection, a marginally performing diode or a sticking Magnetron. Except for the Magnetron all other repairs would be worth the expense.
Repair costs and parts for most everything else will be between $65 and $100.00 depending on the part(s) replaced. Replacing the Magnetron would cost more than 50 % of the total unit replacement cost.
remove bottom panel,< screws along front and tips down > the turntable motor is in the middle. Unplug motor and use multi-meter< insert probes into plug end > run short cycle with something inside of unit," glass of water ", if you have voltage here then the motor is bad and needs replaced. If not then mother board most likely problem.
