Maytag Refrigerator dE — Defrost System Error

Maytag Refrigerator · Error code dE

Defrost cycle did not complete properly. Evaporator coil may be icing over, restricting freezer airflow.

Symptoms

  • dE displayed
  • Freezer cold but fresh food warm
  • Ice buildup on rear evaporator panel
  • Fan noise from freezer (fan hitting ice)

Common Causes

1
Failed defrost heater

Open heater element.

2
Failed defrost thermostat/bimetal

3
Failed defrost sensor

Thermistor on evap not reading correctly.

4

How to Fix It

  1. Empty the freezer and remove the rear inner panel to expose the evaporator.
  2. Thaw any ice buildup with a hair dryer on low — protect plastics.
  3. Test the defrost heater resistance (typically 25-50 ohms).
  4. Test the defrost bimetal/thermostat for continuity when cold.
  5. Test the defrost thermistor at ~16k ohms at 32°F.
