How to Fix Refrigerator Error
- UNPLUG refrigerator.

- Inspect for burnt components or water damage.
- Verify power input to board (120V AC).
- Test output to defrost heater during forced defrost cycle (DANGEROUS – live voltage testing).
- If board receives power but provides no output during defrost command, replace defrost control board.
- If integrated with main board, replace entire main control board assembly.
- After replacement, monitor defrost cycles for 48 hours to verify proper timing (typically every 8-12 hours of compressor run time).
