Bosch Microwave display not working

If your Bosch microwave display is not working, start by checking whether the control panel buttons respond. A defective Bosch microwave control module is the most likely cause when the buttons are unresponsive and the digital display is dark. If your model does not use a separate display board, a failed touchpad and control panel can cause a blank microwave screen or clock display. When the display goes out partially or shows missing segments, the display board is more commonly at fault. If the microwave screen is completely blank, either the main control board or display board may be defective. Also confirm the microwave is plugged in, test the wall receptacle with another appliance, and check the circuit breaker for an incoming power problem. A control board can also fail when it has power but the display remains off. Enter your Bosch 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 handled carefully because the high-voltage capacitor can store a lethal charge even after the microwave is unplugged. Proper capacitor discharge is required before interior work, so use a qualified technician if you are not familiar with that procedure.

05 - Incoming Power Problem

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 - Bosch 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.

07 - Power reset

A microwave display not working may be due to a power outage or power surge. 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.
