Kenmore Refrigerator Error Code E IS

The E IS code indicates an icing sensor error, meaning the main control board has detected a short, open circuit, or abnormal resistance reading from the ice compartment temperature sensor. This sensor monitors conditions inside the ice-making section of the refrigerator. The error may cause ice-making functions to stop until the problem is corrected.

A power reset may temporarily clear the E IS code, but it will return if the underlying issue with the sensor or its wiring is not repaired. Resetting is useful for confirming whether the fault is intermittent or persistent, but it is not a fix. The sensor connection and resistance should be diagnosed before relying on a reset.

Repair costs depend on the root cause. If only a loose connector needs reseating, the repair may cost little to nothing beyond a service call fee, typically in the range of $75 to $150. A replacement icing sensor usually costs between $20 and $60 for the part, with labor adding to the total. A main PCB replacement is the most expensive scenario, with parts and labor potentially ranging from $200 to $500 or more depending on the model.

A knowledgeable DIYer can start by checking the connector at the main PCB, specifically CON5 pins 11 and 12, to ensure it is fully seated and free of corrosion. If you have a multimeter, you can also test the sensor resistance to determine whether the sensor itself has failed. Replacing the sensor is a straightforward repair if you are comfortable with basic appliance disassembly, but board-level repairs should be left to a qualified technician.

The E IS error itself does not indicate a safety hazard such as a fire or refrigerant leak risk. However, a malfunctioning icing sensor can cause the ice maker to operate incorrectly, potentially leading to ice production problems or compartment temperature irregularities. It is best to address the error promptly to avoid secondary issues with food or ice quality.
