Sometimes Display Turns Off When Door is Opened & Keypad Intermittent
My GE JVM1752SP1SS microwave has a few different symptoms, and they are intermittent, making diagnosing difficult.
- Sometimes when the door is opened, the display turns off and the inside light turns off. After closing the door, it may take 1 minute or so for the display to turn back on with gibberish that clears up when pressing the Clock button.
- If the power is turned off/on at the circuit breaker or at the plug, the display will remain blank for at least 1 minute before displaying gibberish, that clears up when pressing the Clock button.
- Sometimes, when the door is closed, the display remains on but none of the buttons on the keypad work, but if I wait about 10 seconds, the keypad will begin to work.
- Sometimes, when the door is closed, the display remains on and the keypad will appear to work properly, but the #3 key won’t work for about 10 seconds, and then it will work normally and can be pressed repeatedly without issue.
Most of the time, the microwave operates normally, but sometimes, these behaviors occur.
The symptoms relating to the intermittent keypad behavior began about 6 weeks ago. The display going dark behavior began about 3 weeks ago.
The first symptom seems to indicate a bad door switch, but all 3 switches operate properly, as verified with my digital volt ohm meter.
Please help me to diagnose my microwave so I buy the right part(s) the first time; I don’t want to just fire a parts cannon at it and end up replacing every part and then buy a new appliance.
