E3Warning
Kenmore Refrigerator E3 Error Code
One of the temperature sensors (thermistors) is reporting an out-of-range value.
Common causes
- Failed thermistor
- Wiring short or open
- Connector corrosion
How to fix it
- Locate the thermistor with the error (typically in fresh food or freezer).
- Measure resistance at room temperature (should be ~10k ohms).
- Replace if resistance is far from spec or open/short.
⚠ When to call a pro: If all thermistors test good but error persists, the control board may be at fault - call a technician.
