Error Code E IS

Icing Sensor Error — short or disconnection of icing sensor (ice maker sensor). Note: E IS displayed without user input indicates icing sensor fault; E IS generated by user action (pressing test switch within 1 week of ice twisting) indicates ice maker mechanical issue.

Also displayed as: E IS

How to Fix

1. 1

   Step 1: Determine if E IS was displayed with or without user input. If displayed without user input, this is icing sensor fault. If displayed after pressing test switch within 1 week, this may be ice maker motor/gear/Hall IC fault.

2. 2

   Step 2: Check connector between Main PCB and icing sensor for loose or disconnected pins.

3. 3

   Step 3: Measure icing sensor resistance at current temperature against the FRZ/Icing Sensor table. At room temperature (~68°F/20°C), expected ~3.14 kΩ. If resistance is 0 Ω (shorted) or infinite Ω (open), replace the icing sensor.

4. 4

   Step 4: If connector and sensor are good, inspect ice maker motor, gear, and Hall IC for mechanical damage or binding.

5. 5

   Step 5: If sensor and mechanical parts are good, replace Main PCB.
