Is your Montgomery Wards microwave display not working? First check whether the control panel buttons respond. A defective control module is the most likely cause when the microwave screen is blank, the clock display is dark, or the buttons do not respond correctly. If your model does not use a separate display board, the touchpad and control panel may be faulty instead. When only part of the display is out or segments are missing, the display board is more commonly defective. If the display is completely dead, either the main control board or display board could be responsible. Also confirm the microwave has incoming power by testing the wall receptacle with another appliance and checking the circuit breaker. If the control board has power but the digital display remains off, the control board may need replacement. Enter your model number to find the exact Montgomery Wards replacement part for your specific microwave. Any repair that requires opening the outer cabinet must be handled carefully. The high-voltage capacitor can store a lethal charge even after the microwave is unplugged, so it must be properly discharged before interior work. If you are not familiar with capacitor discharge procedures, use a qualified technician.
