When your Goldstar microwave display is not working, first confirm the microwave is plugged in and the wall receptacle has power. Check the circuit breaker, then plug in another small appliance to test the outlet. If the microwave has power but the screen is blank, dark, or missing segments, press every control panel button. If none respond correctly, the control module is the most likely cause. On models without a separate display board, a defective touchpad and control panel can cause both the microwave display and buttons to stop working. A display that is only partially out usually points to the display board, while a completely dead display may be caused by the main control board or display board. If the board has power but the digital display remains off, the control board may need replacement. Enter your Goldstar microwave model number to find the exact replacement control module, touchpad, main control board, or display board for your appliance. Any repair that requires opening the outer cabinet must be done carefully because the high-voltage capacitor can store a lethal charge even after unplugging. Proper capacitor discharge is required before interior work, so use a qualified technician if you are not familiar with that procedure.

Confirm the microwave is plugged in and there is power at the wall receptacle. You can plug another small appliance into the receptacle to confirm there is power. If there is no power, confirm the circuit breaker has not tripped.

06 - Goldstar Microwave Control Board
Since the control board is a part of the digital display, a defective board could be responsible for a microwave display not working, if the control board has power to it but the display is not working replace the control board.
