SOLVED: Why the lights and timers work but the unit won’t turn on. – GE Microwave Oven

Make indisputable your life insurance is paid up and there is no suicide article in it. Because working on one of these might be considered suicide. I wo n’t touch the inside of one like this .
lawsuit 1
diode
The diode converts the A/C power output of the transformer to D/C, doubling the voltage to about 5,000 volts. This high voltage powers the magnetron to heat the food. If the diode burns out, the magnetron won ’ t receive enough electric potential to operate, preventing the microwave from heating. When the diode fails, it is frequently visibly burned out. Inspect the diode and if the diode is burned out, replace it. If inspecting the diode proves inconclusive, test it with a multimeter that uses a 9-volt barrage or put a 9-volt battery in serial with the diode. When the leads are reversed, the diode should only have continuity in one steering. ( Warning : The microwave oven can store a deadly amount of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. due to the high ladder voltage and the potential for electric shock, it is highly dangerous to replace the electronic components in a microwave. only a accredited technician should replace the diode. )

Door Switch

Most microwaves have three or four door switches. When the microwave doorway closes, the doorway switches actuate in succession to ensure that the door is closed properly. If any of the door switches fails, the microwave will not start or heat. To determine if any of the doorway switches are defective, use a multimeter to test each of the switches for continuity. If any of the door switches does not have continuity, replace it. ( caution : The microwave oven can store thousands of volts of electricity in its high electric potential capacitor, evening after the microwave oven has been unplugged. due to the potential for electric shock, it is highly dangerous to replace the electronic components in a microwave. only a license technician should replace a door switch. )

Magnetron
The magnetron uses high gear electric potential, high current DC office to generate the microwave frequency that cooks the food. If the magnetron burns out, the microwave won ’ triiodothyronine heat. The magnetron is not repairable—if the magnetron is burned out, you must replace it. ( Warning : The microwave oven can store a deadly come of electricity in its high gear electric potential capacitor, even after the microwave oven has been unplugged. ascribable to the high tend electric potential and the potential for electric shock, it is highly dangerous to replace the electronic components in a microwave. lone a accredited technician should replace the magnetron. )
