Hey there! If your Whirlpool refrigerator is displaying the ‘iT’ error code, don’t fret – it’s a common issue pointing directly to your ice maker. This code specifically indicates a problem with the temperature sensor (thermistor) inside your ice maker assembly, meaning your fridge isn’t getting accurate readings to produce ice efficiently. Let’s get to the bottom of it and get your ice maker working perfectly again!
Possible Reasons for the ‘iT’ Error
- A faulty ice maker thermistor is unable to accurately measure temperature.
- Loose or corroded wiring connections leading to the thermistor.
- The entire ice maker assembly might be failing, including its integrated components.
- Water or ice build-up affecting sensor operation.

Resolving the ‘iT’ Error: A Step-by-Step Guide
- Safety First: Unplug your Whirlpool refrigerator from the wall outlet before beginning any inspection or repair work. This crucial step prevents electrical shock.
- Access the Ice Maker: Open the freezer door and locate the ice maker assembly. Depending on your specific model, you may need to remove a retaining clip or a few screws to pull it forward or detach it.
- Inspect Wiring: Carefully examine all wires connected to the ice maker and especially to the thermistor itself. Look for any visible damage, frayed wires, or loose connections. Secure any loose wires that might be causing an intermittent signal.
- Test the Thermistor (Advanced): For those comfortable with a multimeter, you can test the thermistor’s resistance. Consult your appliance’s service manual for the expected resistance values at various temperatures. A reading far outside the specified range confirms a faulty thermistor.
- Replace the Thermistor: If the thermistor is a separate, replaceable component on your specific Whirlpool model, disconnect the old one and install the new part. Ensure all connections are secure and properly seated.
- Replace the Ice Maker Assembly: In many modern Whirlpool models, the thermistor is integrated directly into the ice maker assembly. If this is the case, or if the thermistor isn’t sold separately for your model, the most straightforward and often recommended fix is to replace the entire ice maker assembly.
- Reassembly and Test: Once the new part is installed, carefully reassemble the ice maker and secure it back in place. Plug the refrigerator back into the wall outlet and monitor its operation over the next 24 hours. The ‘iT’ code should clear, and ice production should resume normally.
