Kenmore Refrigerator Error Code i1

The i1 code means the refrigerator's control board has detected a problem with the icemaker room temperature sensor. The sensor is being read as open or shorted, or the icemaker heating element did not perform correctly during a harvest cycle. The refrigerator will typically suspend ice production when this code is active. Checking the wiring connections at the sensor and main PCB is the recommended first step.

The i1 code specifically affects the icemaker system and does not typically interfere with the refrigerator or freezer cooling functions. Your food should remain safely refrigerated. However, ice production will likely be disrupted or stopped until the fault is resolved, so you should address the issue promptly to restore normal icemaker operation.

A power reset may temporarily clear the i1 code from the display, but the code will return if the underlying fault is still present. The sensor, heater, or wiring issue needs to be diagnosed and corrected for the code to stay cleared. Resetting without repair is not a substitute for proper diagnosis and may delay finding the actual problem.

A knowledgeable DIYer can start by inspecting and reseating wiring connectors at the icemaker sensor and main PCB, which sometimes resolves the fault at no cost. Testing the sensor and heater with a multimeter requires basic electrical skills and comfort working inside the refrigerator. If the sensor or heater needs replacement, those parts are generally available, but if the main PCB is suspected, professional diagnosis is recommended.

Repair costs depend on the root cause. If only a wiring connector needs reseating, there may be no parts cost, though a service call fee typically ranges from $75 to $150. A replacement icemaker sensor or heater part generally costs between $20 and $80 for the part alone. If the main PCB requires replacement, expect parts and labor combined to range from $200 to $450 or more.
