Freezer too cold, ice cream rock hard and items covered in frost, while refrigerator may be colder than setpoint.

Safety: Unplug the refrigerator before accessing controls or sensors.

• 1. Verify settings: Ensure the temperature controls are not set to maximum cold. Adjust to mid-range and monitor for 24 hours.
• 2. Check thermostat (mechanical models): Turn the dial from coldest to warmest and listen for a click. If no click and the compressor never shuts off, replace the temperature control thermostat.
• 3. Inspect thermistors (electronic models): Access the refrigerator and freezer thermistors and test their resistance at known temperatures. Replace any that are out of specification.
• 4. Control board: If sensors and thermostat are good but the compressor runs excessively, the main control board may be mismanaging the cycle and require replacement.
• 5. Avoid blocking sensors: Do not place items directly against the sensor covers; this can cause false readings and overcooling.
