What Does Error E3 Mean?
The Amana Refrigerator E3 error indicates a malfunction in the temperature sensor, typically the evaporator thermistor. This can lead to erratic temperature readings, inconsistent ice production, and the refrigerator drifting away from the set temperature. If this error code appears, it may also signify issues with the defrost thermostat or wiring connections near the evaporator sensor.
Common Symptoms:
- E3 code displayed on refrigerator panel
- Ice production stops or becomes inconsistent
- Refrigerator temperatures drift from setpoint
Possible Causes
- Faulty evaporator thermistor (temperature sensor) (medium)
- Open or faulty defrost thermostat (medium)
- Wiring harness or connection fault near the evaporator sensor circuit (medium)
How to Fix Error E3
DIY Fix Basic Visual Inspection and Reset
- Unplug the refrigerator from power for safety.
- Inspect the freezer section for heavy frost buildup that could insulate sensors.
- Allow any visible frost buildup to melt naturally or manually defrost following manufacturer safety guidance.
- Reconnect power and observe if E3 persists.
Technician Only Diagnose and Replace Faulty Sensor Components
- Disconnect power and remove freezer back panel to access evaporator area.
- Locate and test evaporator thermistor resistance against manufacturer specs at known temperatures.
- Check defrost thermostat for continuity when cold.
- Inspect wiring harnesses for damage, corrosion, or loose connectors.
- Replace any sensor or thermostat that tests out of specification.
- Reassemble and test refrigerator for error code clearance.
Parts needed: Evaporator thermistor, Defrost thermostat, Wiring harness/connectors
- If error code persists after basic diagnostics and sensor replacement attempts.
- If wiring harness damage is extensive or in hard‑to‑access locations.
- If user is not comfortable performing internal diagnostics.
