⚠️ Safety Warning: Appliance repair involves electricity, gas, and moving parts. Always disconnect power before working on any appliance.
Error Code: Refrigerator Difficulty: Hard
Problem: General system error – main control board detected uncorrectable fault in compressor drive circuit or sensor array
How to Fix Refrigerator Error
- Unplug refrigerator for 10 minutes to reset microprocessor.
- If Er returns immediately on power-up: main board failure likely.
- Remove rear access panel and inspect main control board W10868991 for visible damage (burnt components, bulging capacitors near compressor terminals).
- Test compressor start relay/overload separately – remove from compressor pins and shake; rattling indicates failed relay. Replace relay kit if faulty before condemning board.
- Measure resistance across compressor windings (common to start/run): should read 3-10Ω each with no shorts to ground.
- If compressor tests good but Er persists, main board has failed compressor drive circuit – replace W10868991 and reprogram with correct code.
- Note: Er code often appears with compressor not starting – always verify sealed system integrity before board replacement.
