Moderate
Address soon - your appliance may not work properly
Also displayed as: E IS
How to Fix
- 1
Check for loose or disconnected connector between Main PCB and icing sensor at CON5 pins 18~17.
- 2
If connector is loose, reconnect or repair the connector.
- 3
Measure sensor resistance at CON5 pins 18~17. If 0 ohm (short), replace the sensor.
- 4
If resistance is infinite/open, check sensor connection harness.
- 5
If sensor connection is normal and resistance is open, replace the sensor.
- 6
Verify resistance matches the temperature table. If discrepancy, replace the sensor.
- 7
If all checks pass, explain normal operation to customer.
- 8
If PCB output is suspect, replace the main PCB.
