GE Microwave Control Board (WB27X29710)

The GE Microwave Control Board is the central electronic component that manages all functions of your microwave or Advantium oven, including cook time, power levels, and keypad input. It receives signals from the touchpad and sends commands to the magnetron, turntable motor, and other components to carry out your selected settings. Without a functioning control board, the microwave cannot interpret or execute any cooking operations. The GE Microwave Control Board can fail due to power surges, moisture exposure, overheating, or normal wear on internal components over time. Burnt circuits or failed solder connections are common causes, often resulting in the board losing the ability to communicate with the keypad or other parts of the microwave. Look for these symptoms to help determine if the control board is the source of your microwave problem: - Microwave display is blank, dim, or showing error codes - Keypad buttons are unresponsive or only work intermittently - Microwave runs on its own without any input - Cooking stops mid-cycle or will not start at all - Turntable, light, or fan stops working while other functions seem normal - Microwave powers on but does not heat food - Control panel appears frozen or resets unexpectedly
