What Does Error E3 Mean?

The E3 error code on your Magic Chef Refrigerator indicates a fault in the evaporator thermistor or defrost sensor. This failure prevents the refrigerator from accurately reading temperatures, causing inconsistent cooling and potentially leading to the unit running continuously or not at all. Addressing this issue is crucial for maintaining optimal temperature control.

Common Symptoms:

  • Display shows E3
  • Refrigerator runs continuously or not at all
  • Poor temperature control or cooling performance

Possible Causes

  • Defrost/evaporator thermistor (temperature sensor) fault (medium)

How to Fix Error E3

DIY Fix Basic checks and reset

  1. Unplug the refrigerator from power for at least 5 minutes to reset control electronics.
  2. Check interior temperatures and ensure nothing is blocking vents.
  3. Observe if E3 clears after reset when power is restored.

Technician Only Inspect/Replace evaporator thermistor and wiring

  1. Unplug the refrigerator and remove interior panels to access the evaporator area.
  2. Locate the evaporator thermistor attached to the evaporator coil.
  3. Inspect thermistor placement and wiring for damage or disconnection.
  4. Test thermistor resistance with a multimeter and compare to manufacturer spec; replace if out of range.
  5. Reassemble and restore power; verify E3 code no longer appears.

Parts needed: Evaporator thermistor sensor, Wiring harness (if damaged)

🛑 When to Call a Pro:
  • If the code persists after resetting and basic checks
  • If sensor/wiring damage is suspected but cannot be safely accessed
