Kenmore Refrigerator Error Code Er IT — Ice Maker Temperature Sensor Error
What this means
The Er IT error code on Kenmore Elite refrigerators indicates the ice maker temperature sensor (thermistor) is malfunctioning. This sensor monitors the temperature of the ice mold to determine when ice is ready to harvest. A failed sensor can cause the ice maker to stop producing ice or to cycle continuously.
Alternate codes: ErIT, Er iT
Step-by-step fix
3 stepsReset the ice maker
Locate the ice maker reset button (on the bottom or side of the ice maker assembly in the freezer). Press and hold for 5–10 seconds. Wait 24 hours to see if ice production resumes and the error clears.
The reset may cycle the ice maker through a test harvest — listen for the motor running.
Test the ice maker temperature sensor
Remove the ice maker assembly from the freezer (usually 2–3 screws). Locate the temperature sensor — a small thermistor connected to the ice mold. Disconnect it and test with a multimeter at room temperature — expect 5,000–15,000 ohms depending on the model.
The thermistor is often a small bead or disc attached to the ice mold tray with an adhesive or clip.
Replace the sensor or ice maker assembly
If the sensor reads open or shorted, replace it. On many Kenmore models, the sensor is integrated into the ice maker and the entire assembly must be replaced.
When reinstalling the ice maker, ensure the water fill tube is properly aligned with the ice mold fill cup.
When to call a professional
If the sensor tests correctly but the error persists, the ice maker module or the main control board may be faulty.
