Error code Er HS displayed, ice production may stop and temperature readings may be inaccurate.

Safety first: Disconnect power before accessing the ice room or control housing.

Steps:

• 1. Locate humidity/ice room sensor: On many Kenmore French-door models, the humidity sensor is located near the ice maker compartment or in the fresh food air duct assembly.
• 2. Visual inspection: Check for moisture intrusion, corrosion on the connector, or physical damage to the sensor body.
• 3. Reseat connector: Unplug and replug the sensor connector several times to clean contacts. Ensure it is fully seated.
• 4. Resistance test: If the service manual provides resistance values, disconnect the sensor and measure with a multimeter. Readings of 0 ohms or OL typically indicate a bad sensor.
• 5. Replace sensor: If the sensor is out of spec or corroded, install a new OEM humidity/ice room sensor. Route wiring as originally installed.
• 6. If sensor appears good: The main control board may be misinterpreting the signal. Board diagnosis or replacement may be required by a technician.
