Moderate
Address soon - your appliance may not work properly
Also displayed as: E rS
How to Fix
- 1
Step 1: Check if the connector between Main PCB and refrigerator sensor is disconnected or loose. If yes, reconnect or repair and retest.
- 2
Step 2: Measure sensor resistance at CON8 20th Pin ~ 19th Pin. If 0 ohms (short), replace the sensor.
- 3
Step 3: If OL/infinite (open), proceed to Step 6.
- 4
Step 4: Compare measured resistance to temperature/resistance table. If resistance is out of spec, replace sensor.
- 5
Step 5: If resistance matches table, explain normal operation to customer.
- 6
Step 6: Check sensor harness continuity to Main PCB. If wiring is intact but error persists, replace the refrigerator Main PCB. If wiring is broken, repair or replace harness.
