Freezer temperature sensor failure

Check/Repair

Unplug the refrigerator and check the wire harness connection on the freezer temperature sensor. Reconnect the wire harness if it's loose. If the wire harness connection is okay, check sensor resistance using a multimeter. The meter should measure about 5,600 ohms if the sensor temperature is 72 degrees (room temperature), 13,290 ohms at 32 degrees and 29,000 ohms at 0 degrees. Replace the temperature sensor if resistance is off by more than 10 percent. If sensor resistance is okay, reinstall the temperature sensor and check the sensor's wire harness connections to the electronic control board (red wire on CN30 and gray wire on CN76). Reconnect the wires if loose. If the wire connections are okay, disconnect the sensor wires from the electronic control board and measure resistance through the sensor's wires. The meter should read the same resistance as for the temperature sensor. If the meter measures correct sensor resistance through the wires, you'll likely need to replace the electronic control board because it's not accurately detecting sensor resistance. Find and repair the sensor wiring failure if the meter measures incorrect resistance through the sensor wires.
