Haier Microwave display not working

If your Haier microwave display is not working, first check whether the microwave has power by testing the wall receptacle with another appliance and confirming the circuit breaker has not tripped. If the microwave has power but the screen is blank or the buttons are also unresponsive, a defective control module is the most likely cause and may need replacement. On models without a separate display board, the touchpad and control panel can cause the microwave display not working symptom. If only part of the digital display is dark or missing segments, the display board is more commonly at fault. A display that is completely out may be caused by either the main control board or display board, while a control board with power but no display may need replacement. Enter your Haier microwave model number to find the exact replacement control module, touchpad, main control board, or display board for your appliance. If diagnosis requires removing the outer cabinet, unplug the microwave first and use proper safety procedures. The high-voltage capacitor can store a lethal charge even after the microwave is unplugged and must be properly discharged before interior work. If you are not familiar with capacitor discharge procedures, have a qualified technician perform the repair.

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.

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.
