GE Microwave Main Control Board Replacement #WB56X20629

This video provides step-by-step instructions for replacing the main control board on GE microwaves. The most common reasons for replacing the main control board are when the microwave won’t heat or doesn’t respond to button presses. All of the information in this main control board replacement video is applicable to the following brands: GE Tools used: Phillips head screwdriver

Microwave

Microwave not heating

The main control board might be defective. However, this is rarely the case. Control boards are often misdiagnosed—before replacing the control board, 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 replace the electronic components in a microwave. Only a licensed technician should replace the main control board.)

Microwave light bulb not working

Before replacing the control, check the light bulbs, sockets, and wiring. If these parts seem to be working properly, test the control board with a multimeter to determine if it sending the correct voltage to the light bulb socket. If the control board is not sending enough voltage to the light bulb socket, replace the control board.

Microwave shuts off after a few seconds

Control boards are often misdiagnosed—before replacing the control board, first check more commonly defective parts, particularly the door switches. If all of the other components are working properly, replace the control board.

Microwave turntable not turning

The main control might be defective. However, the turntable motor is much more likely to be at fault. First, check the incoming power to the turntable motor. If the turntable motor is not getting power, the main control board may be at fault.

Microwave buttons not working

To determine if the control and display board is defective, try pressing each of the buttons on the control panel. If none of the buttons are responding correctly, it is possible that the main control is defective.

Microwave display not working

If the display goes out partially, the display board is more commonly at fault. If the display isn’t working at all, either the main control board or the display board could be at fault.

Microwave turns on by itself

First, make sure that the touchpad is working properly. If the touchpad is working properly, the main control board is likely at fault. If the control board is defective, replace it.

Microwave is sparking or arcing

If the microwave is sparking or arcing in the cabinet area, and not in the oven cavity, you will likely see smoke or there will be a burning smell. The appliance's main control board is one of the components that could be damaged and causing the sparking or arcing, although this is rarely the case. Inspect the control board for burn marks or damage and replace if necessary, although you should confirm that other more likely defective components are functioning properly first.

Microwave exhaust fan not working

The main control board might be defective. However, this is not usually the case. Before replacing the control board, first check the exhaust fan motor and wiring. If the exhaust fan motor is not getting power, the main control board might be at fault.

Microwave producing a burning smell

The main control board may have a burnt component. Inspect the control board for burnt or melted components. If you find burnt components 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 replace the electronic components in a microwave. Only a licensed technician should replace the main control board.)

Microwave won't turn off

The main control board has relays that send power to several components to make the microwave work. If one or more of the relays or triacs short out, some of the components can keep running when the controls are turned off.  (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 replace the electronic components in a microwave. Only a licensed technician should replace the main control board.)
