Problem: Critical control board failure – EEPROM corruption or hardware fault preventing normal operation
How to Fix Refrigerator Error
- Unplug refrigerator for 15 minutes – if
- 8 returns immediately on power-up, board is defective.
- Remove rear access panel and inspect main control board W10868991 for visible damage (burnt components, swollen capacitors).
- Check all harness connections – especially J1 power input – for loose/corroded pins.
- Verify proper household voltage (110-125VAC) at outlet.
- If board shows no physical damage but
- 8 persists, EEPROM has failed – replace main control board with exact OEM match.
- AFTER replacement: MUST enter programming mode and input correct 4-digit code from serial plate sticker. Failure to program correctly causes permanent lockout.
- Note:
- 8 often appears after power surge – install whole-house surge protector to prevent recurrence.
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
