Jenn Air Microwave display not working

Is your Jenn Air microwave display not working? Start with the control module. Press each control-panel button. If the buttons are unresponsive or respond incorrectly, the control module is likely defective and may need replacement. On models without a separate display board, a failed touchpad and control panel can cause a blank microwave screen or a microwave clock display not working. If only some digits or segments are missing, the display board is the more likely problem. If the display is completely dark, 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 reset a tripped circuit breaker before replacing parts. A control board can also fail when it has power but does not operate the digital display. Enter your model number to find the exact Jenn Air replacement control module, touchpad, main control board, or display board for your microwave. 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. It must be properly discharged before interior work, so use a qualified technician if you are not familiar with capacitor discharge procedures.

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 - Jenn Air 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.
