How to Fix

  1. 1

    Step 1: Check if the connector between Main PCB and refrigerator sensor is disconnected or loose. If yes, reconnect or repair the connector.

  2. 2

    Step 2: Measure sensor resistance at CON8 pins 20 to 19. If resistance is 0 Ω (short), replace the sensor.

  3. 3

    Step 3: If resistance is open (infinite/OL), proceed to Step 6.

  4. 4

    Step 4: Compare measured resistance to the temperature/resistance table for refrigerator/defrost sensor. If resistance does not match expected value, replace the sensor.

  5. 5

    Step 5: If resistance is within spec, explain to customer (normal operation).

  6. 6

    Step 6: Check the sensor harness connection. If the sensor connection is normal, replace the refrigerator main PCB. If not, reconnect or repair the connector.
