If the timer works then it is possible that the magnetron is faulty provided the high volatge flows in thrrough the mains transformer and the coupled capacitor.
If the magnetron seems good , then check the transformer and the capacitor.If suspect change and proceed.
Please check the fuse to this unit and also if the relay engages the power to the magnetron. If not check the relay drive and replace the drive transistor if faulty.
Credit if the advice helps.

I would strongly consider replacing the microwave oven, prices have dropped considerably. The problem you are describing is in the keypad controller board.

Microwave wont heat up food


If your microwave runs, but doesn'theat your food, verify that you have selected a cooking setting. You mayaccidentally set the timer. Test the magnetron by placing 1 cup of water in themicrowave and heating the water for three minutes. If the water doesn't heat,your magnetron is dead.

My GE spacemaker microwave doesn't heat up foods. There is a slight bit of heat generated but not much. All timers, lights, etc. work normal. It is a GE model jvm1440. It is about 3 years old. The problem...


IT COULD BE A NUMBER OF THINGS RANGING FROM DIODES TO CAPACITORS TO YOUR MAGNATRON OR THERMOSTAST OR TRANSFORMERS. IT'S DIFFICULT TO DIAGNOSE WITHOUT SEEING THIS MICROWAVE. YOU MAY BE BETTER OFF GETTING YOURSELF A DIFFERENT ONE.

Can't use the microwave at all


you have either a bad keypad or control board.

If you have operation of some buttons and not others its the keypad. if you have no operation out of the buttons at all you have a bad control board.

If you turn your microwave on and it sets and the timer counts down you have a bad interlock switch..

please let me know exactly what your microwave does when you set the cook time
