Defrost Sensor (Freezer Defrost Sensor) Error

Moderate

Address soon - your appliance may not work properly

How to Fix

  1. 1

    Check for loose or disconnected connector between the defrost controller assembly and the sensor. If disconnected, reconnect.

  2. 2

    Measure sensor resistance at CON8, 26th Pin to 25th Pin. If resistance is 0 Ω (sensor short), replace the sensor.

  3. 3

    If resistance is open/infinite (OL), replace the refrigerator (PCB/sensor assembly).

  4. 4

    Compare measured resistance to temperature-resistance table. If no problem found, explain normal operation to customer.

  5. 5

    If resistance does not match expected value for current temperature, replace the sensor.
