Error Code 85E
AC mains input voltage below safe minimum threshold
Critical
Stop using immediately - risk of damage or safety issue
Also displayed as: 85 E
What This Means
Low AC mains voltage below 55V (at 110V input) or 106V (at 220V input); Defective resistor divider for voltage sensing (R309, R310, R311); Loose power supply connections
What actually causes this:
Weak home electrical supply, loose connection at breaker, or voltage drop in wiring
First Thing to Check
Check AC voltage at refrigerator outlet with multimeter, should be 110-127V or 220-240V
Parts Involved
How to Fix
- 1
Check AC input voltage at wall outlet with multimeter
- 2
Verify resistors R309, R310, R311 on PCB are not burnt or damaged
- 3
Check power supply transformer connections are secure
