This issue may stem from a faulty freezer temperature sensor or a problem within the defrost system. It's essential to address this promptly to maintain optimal cooling performance.
Common Symptoms:
- Error code "ER" displayed on control panel
- Possible cooling irregularities (e.g., freezer not reaching proper temperature)
Possible Causes
- Freezer sensor or defrost system fault (community technician report) (low)
How to Fix Error ER
DIY Fix Basic reset and inspection
- Unplug the refrigerator from power for ~5–10 minutes to allow any control board resets.
- Plug the refrigerator back in and observe if the ER code returns.
- Ensure vents inside the fridge/freezer are not blocked by food items so airflow is maintained.
Technician Only Inspect sensors and defrost components
- Disconnect power to the refrigerator.
- Access the freezer and evaporator area to locate the freezer temperature sensor/thermistor and defrost components.
- Test the freezer temperature sensor and defrost thermostat/heater for continuity with a multimeter.
- Inspect wiring harnesses for loose connections or damage between sensors, control board, and defrost components.
- Replace any failed sensors or defrost parts as indicated by testing.
Parts needed: Freezer temperature sensor/thermistor, Defrost thermostat, Defrost heater, Wiring harness/connectors
- If error persists after basic reset and safe inspection
- If the user is not comfortable accessing interior components or performing electrical diagnostics
