Kenmore Refrigerator Error Code i2

The i2 code means the icemaker room temperature sensor is reading as open or shorted at the Main PCB. The control board cannot get a valid temperature signal from that sensor, so it flags the fault. This typically points to a wiring connection problem or a failed thermistor in the icemaker compartment.

A reset may temporarily clear the i2 code from the display, but if the underlying sensor or wiring fault is still present, the code will return. Clearing the code without addressing the root cause does not restore proper icemaker temperature monitoring. A proper repair to the sensor or wiring is required for the code to stay cleared.

If only a connector needs reseating or cleaning, the cost can be minimal, covering just a service call fee in the range of $75 to $150. If the icemaker room thermistor requires replacement, parts typically cost in the $15 to $50 range plus labor. A Main PCB replacement, if needed, is significantly more expensive, generally ranging from $150 to $400 or more depending on the model and labor rates in your area.

Start by checking all wiring connectors between the icemaker room sensor and the Main PCB, ensuring they are fully seated and free of corrosion or damage. If the connectors are secure, test the thermistor with a multimeter to determine if it is reading open or shorted. A faulty thermistor will need to be replaced, and if the sensor and wiring both test correctly, the Main PCB should be evaluated.

The i2 code is not an immediate safety hazard, but it does mean the refrigerator cannot monitor or control the icemaker compartment temperature properly. This can result in ice production stopping or the icemaker behaving erratically. It is best to address the fault promptly to avoid prolonged issues with ice production or potential food safety concerns if compartment temperatures are affected.
