Error Code 2E
Refrigerator temperature sensor communication failure
Critical
Stop using immediately - risk of damage or safety issue
Also displayed as: 2 E
What This Means
Connector slipped out or open contact; Wire cut or short-circuited; Abnormal sensing temperature above 50°C or below -50°C
What actually causes this:
Loose connector, cut wire, or faulty thermistor in refrigerator temperature sensing circuit
First Thing to Check
Disconnect and reconnect CN30 connector at main PCB to ensure proper seating
Parts Involved
How to Fix
- 1
Check voltage between MAIN PCB CN30 #5 and #7, should be 4.5V to 1.0V
- 2
Verify connector is properly seated
- 3
Check thermistor resistance
