KitchenAid Refrigerator Error Code 1E — Freezer Sensor Error
What this means
Error code 1E indicates the freezer section temperature sensor (thermistor) is reading as either open or shorted. The sensor provides temperature data to the control board to regulate the compressor and defrost cycles. A faulty sensor can cause the freezer to run too cold, not cold enough, or trigger constant defrost cycles.
Step-by-step fix
4 stepsAccess the freezer sensor
Unplug the refrigerator. Open the freezer door and remove the interior back panel (usually held by a few screws or clips) to access the evaporator area where the sensor is located.
Remove any food and shelves that block access to the back panel.
Locate and disconnect the sensor
Find the freezer temperature sensor — it is a small component clipped to or near the evaporator coils with a wire harness connected to it.
The sensor is typically a small bead or cylinder with two wires.
Test the sensor
Disconnect the sensor and measure its resistance with a multimeter. At 32 degrees F (0 degrees C), the sensor should read approximately 16,000-17,000 ohms. At room temperature (77 degrees F), it reads approximately 5,000-6,000 ohms.
OL (infinity) indicates an open circuit; near zero indicates a short. Both mean the sensor is faulty.
Replace the sensor
Unclip the old sensor, disconnect the wire harness, and install the new sensor in the same location. Reassemble the back panel.
Route the sensor wire carefully so it does not get pinched when the panel is reinstalled.
When to call a professional
If the sensor tests good but the error persists, the control board's sensor input circuit may be faulty. Professional diagnosis is recommended.
