The E2 error code on a Kenmore freezer indicates a fault with the evaporator temperature sensor. The control board uses this sensor to manage defrost cycles and compressor operation.
Causes
- Failed evaporator thermistor
- Ice buildup around the evaporator sensor
- Sensor wiring damage from ice or physical contact
What To Do
- Manually defrost the freezer completely — sometimes ice buildup dislodges or breaks sensor wiring.
- After defrost, check whether E2 clears on restart.
- If E2 returns, the evaporator sensor requires professional replacement.
