Error Code E rS
Refrigerator Sensor Error — short or disconnection of refrigerator sensor
Moderate
Address soon - your appliance may not work properly
Also displayed as: E rS
How to Fix
- 1
Step 1: Check if connector is disconnected or loose between Main PCB and sensor. If yes, reconnect or repair the connector.
- 2
Step 2: Measure sensor resistance. If resistance is 0 Ω (sensor shorted), replace the sensor.
- 3
Step 3: Measure sensor resistance. If resistance is infinite/open (sensor open), replace the sensor.
- 4
Step 4: Check sensor resistance at measured ambient temperature against the resistance table (CON7, 15th pin to 18th pin). Values range from 38 kΩ at 23°F to 16 kΩ at 59°F.
- 5
Step 5: If resistance is normal for the current temperature, explain to customer that unit is operating correctly.
