Moderate
Address soon - your appliance may not work properly
Also displayed as: E rS
How to Fix
- 1
Check CON4 connector (pins 15~16) between Main PCB and refrigerator sensor for loose or disconnected condition.
- 2
If connector is loose/disconnected, reconnect or repair the connector.
- 3
Measure sensor resistance at CON4 pins 15~16: 0 ohm = short (replace sensor), Open/infinity = open (replace sensor).
- 4
Compare measured resistance to temperature chart: -5°C=38k, 0°C=30k, 5°C=24k, 10°C=19.5k, 15°C=16k ohms.
- 5
If resistance is normal and matches temperature, explain situation to customer.
- 6
If sensor repeatedly fails after replacement, replace the Main PCB.
