What Does Error E3 Mean?

The Westinghouse Refrigerator E3 error code indicates a malfunction with the temperature sensors, primarily affecting the ambient temperature sensor in the freezer section and the ice thickness sensor in the ice maker subsystem. This error often leads to erratic temperature readings, unresponsive temperature adjustments in the freezer, and ice maker failures. Addressing this issue promptly is essential to maintain proper cooling and ice production.

Common Symptoms:

  • Refrigerator/freezer displays E3 code on panel
  • Temperature adjustment not responding correctly in freezer section
  • Ice maker fails mid‑cycle or does not harvest ice

Possible Causes

  • Ambient/Room Temperature Sensor Fault (freezer section) (medium)
  • Ice Thickness Sensor/Probe Failure (ice maker subsystem) (medium)

How to Fix Error E3

DIY Fix Basic Checks for E3 Related to Sensors

  1. Unplug the refrigerator to ensure safety before inspection.
  2. Check that freezer and fridge doors are fully closed and sealed.
  3. If the fridge has an ice maker, inspect visible sensor arms/probes for scale buildup and gently clean with mild solution if accessible.
  4. Observe if the E3 code persists after a full power reset (unplug for several minutes then restart).

Technician Only Sensor Diagnosis and Replacement

  1. Access the freezer ambient temperature sensor location (likely near the control panel or grille) and check for proper seating and wiring continuity.
  2. Test ambient NTC sensor resistance against expected values; replace if open, shorted, or out of spec.
  3. Inspect and test the ice maker’s ice thickness sensor/probe; clean or replace if faulty.
  4. Verify associated wiring harness connectors at sensors and control board are secure and free of corrosion.

Parts needed: Ambient temperature NTC sensor (freezer), Ice thickness sensor/probe

🛑 When to Call a Pro:
  • If sensor testing indicates open/short conditions and replacement does not clear E3
  • If wiring harness damage is suspected
  • If the control board input circuit is suspected after sensor verification
