What 4E Means on a Kenmore Freezer
The 4E error code indicates a defrost temperature sensor failure. This sensor specifically monitors the temperature of the evaporator coil during defrost cycles and is separate from the main thermistor.
Common Causes
- Failed defrost sensor
- Ice encasing the sensor causing false readings
- Wiring damage
What You Can Do
- Manually defrost and check if the error clears.
- If error returns after defrost, the sensor needs replacement.
