What Does Error E1 Mean?
The Westinghouse Refrigerator E1 error code indicates a malfunction in the internal temperature sensor, which may lead to inaccurate temperature readings and unusual operational sounds. This issue often stems from a faulty thermistor or damaged wiring. A power reset may temporarily clear the error, but if the problem persists, further investigation is necessary to identify and rectify the underlying cause.
Common Symptoms:
- E1 code displayed on the refrigerator control panel
- Refrigerator not maintaining proper temperature
- Error persists after simple power reset
Possible Causes
- Faulty internal temperature sensor (thermistor) (medium)
- Damaged or disconnected sensor wiring/connectors (medium)
- Control board interpretation/sensor circuit issue (low)
How to Fix Error E1
DIY Fix Perform a basic power reset
- Unplug the refrigerator from mains power.
- Wait 5–10 minutes.
- Plug the unit back in and observe if the E1 error clears.
DIY Fix Inspect accessible sensor wiring
- Locate the interior temperature sensor/thermistor (often clipped to the liner or behind an interior cover).
- Check for visible damage or loose connectors.
- Ensure connections are properly seated.
Technician Only Test and replace the internal temperature sensor
- Disconnect mains power.
- Access and remove the interior temperature sensor/thermistor.
- Use a multimeter to measure resistance vs expected values at known temperatures.
- Replace the sensor if readings are out of specification.
Parts needed: Replacement temperature sensor/thermistor, Insulated connectors if wiring repair is needed
Technician Only Diagnose control board sensor input circuit
- Verify continuity from sensor harness to the control board.
- Inspect control board for burnt/corroded components or failed sensor input.
- Replace control board if the sensor circuit is proven faulty.
Parts needed: Control board
- If you are uncomfortable accessing interior panels or using test equipment.
- If sensor and wiring test normal yet the error persists, indicating possible control board fault.
