Kenmore 111 model top-freezer refrigerator error codes

The ambient temperature sensor (also called RT-sensor) attaches to the top of the refrigerator. Unplug the refrigerator and check the temperature sensor wiring connected to the control board for damage and repair any broken wires. Measure the resistance through the ambient temperature sensor circuit from the control board. Replace the ambient temperature sensor if resistance isn't between 5,000 and 40,000 ohms.

The defrost temperature sensor monitors evaporator temperature. Unplug the refrigerator and check the temperature sensor wiring connected to the control board for damage and repair any broken wires. Measure the resistance through the defrost temperature sensor circuit from the control board. Replace the defrost temperature sensor if the resistance isn't between 5,000 and 40,000 ohms.

Unplug the refrigerator and check the wiring between the door switch and the control board. Reconnect any loose wires and repair any broken wires. If the wiring is okay, unplug the door switch wire harness from the control board. Check for continuity through the door switch with the plunger pushed in. If you don't measure continuity, replace the door switch.

Measure the resistance through the defrost heater circuit from the control board. Replace the defrost heater if resistance isn't between 50 and 70 ohms.
