Problem: Intermittent door switch fault – microswitch making/breaking contact causing False door-open signals
How to Fix Refrigerator Error
- Observe which door’s light blinks erratically – indicates faulty switch on that door.
- Remove door switch cover (typically snaps off).
- Depress switch plunger manually while monitoring continuity – should transition cleanly between open/closed states.
- If intermittent continuity, replace door switch WPW
- Inspect switch mounting for loose screws causing misalignment.
- If switches test good but blinking continues, main control board W10868991 has failed input circuit – replace board after verifying all switches/wiring.
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
