Common solutions for: Microwave not working
01 - Switch Holder
The microwave switch holder is the component that houses the door switches behind the control panel. If the switch holder is damaged or misaligned, one of more switches may not be actuated when the microwave door is closed, resulting in the microwave not working. You will need to uninstall the control panel and inspect the switch holder to confirm it is in good condition and secured properly. Replace the switch holder with a new one if necessary.

02 - Main Control Board
The main control board might be defective. However, this is rarely the case. Control boards are often misdiagnosed—check all of the more commonly defective parts. If you have determined that all of the other components are working properly,replace the main control board. (Caution: The microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. Due to the potential for electric shock, it is extremely dangerous to repl...ace the electronic components in a microwave. Only a licensed technician should replace the main control board.)

03 - Incoming Power Problem
The electrical outlet may not be getting power. To determine if the outlet is getting power, try plugging something else into the outlet. If the outlet is not getting power, check the home circuit breakers or fuses.
Highly Likely
04 - Power reset
After a power surge or power outage, appliance operation could be temporarily affected. Full operation can sometimes be restored through a power reset by either unplugging the unit's power cord for a few minutes and then plugging it back in or switching off the circuit breaker for the microwave then switching it back on.
Common
05 - Door Switch
Most microwaves have three or four door switches. When the microwave door closes, the door switches actuate in sequence to ensure that the door is closed properly. If any of the door switches fail, the microwave will not start or heat. To determine if any of the door switches are defective, use a multimeter to test each of the switches for continuity. If any of the door switches do not have continuity, the switch or switches should be replaced.
