Answer Hi Kenny.Door Alarm= Whenever the door is left open, the red Door Ajar LED will illuminate. If the door is left open for longer than 5 minutes, the audible alarm sounds. The display will not change. Close the door or press the Alarm Reset key to turn the audible alarm off. The Door Ajar LED remains on until the door is closed. When the door is closed, the Door Ajar alarm time period is reset. If the thermistor(Cavity temperature sensor) is bad it will show E8 or E9 code. If the E7 code will be a fail safe code meaning the stuck keypad. In your case you need to replace the control board assy. part # 297366300. Thank you.The control assembly unsnaps out of the door. You can use a flat blade putty or butter knife to unsnap the unit out of the door. The disconnect the wires and connect them to the new board and snap it into place. Thank You.
