Question about GE Microwave Ovens
All smartcard pad functions work. Turntable turns but water in cup does not heat. Fuse is replaced as well as magnetron. The unit still does not work.
Did you replace the DIODE ? a bad magntron will kill a diode . allways replace together you do not need to replace the capacator except when the diode is a part of it (inside).........Please if this answer helped , please rate this 3 or 4 stars . and keep me in the paid answer department .

If there is no action please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Make sure that the program controller is working if not check power - step dwon suppy, the pads are responding- if not fauty pads- or the door switches ,if contact is not through the microwave willnot work.
Now keeping clear of the microwave, switch on , use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is heating without any issues , you can use the microwave safely
