![]() ![]() Find and repair the sensor wiring failure if the meter measures infinite resistance through the sensor wires. 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. The meter should read the same resistance as for the temperature sensor. Unplug the J4A connector from the control board and measure resistance through the gray/black wires. If the meter measures correct resistance through the sensor, plug the temperature sensor back in and measure resistance through the refrigerator temperature sensor wires that connect to the electronic control board (the gray/black wires on the J4A connector). Replace the sensor if the meter measures infinite resistance. The meter should measure 28,300 ohms if the sensor temperature is 37 degrees, 32,566 ohms at 32 degrees and 11,304 ohms at 72 degrees (room temperature). If wiring is okay, unplug the refrigerator temperature sensor from its wire harness and measure the resistance of the sensor using a multimeter. Unplug the refrigerator and check wiring connections between the refrigerator temperature sensor and the electronic control board. Find and repair the sensor wiring failure if the meter measures less than 10 ohms of resistance through the sensor wires. Unplug the J4A connector from the control board and measure resistance through the gray/white wires. If the meter measures correct resistance through the sensor, plug the temperature sensor back in and measure resistance through the freezer temperature sensor wires that connect to the electronic control board (the gray/white wires on the J4A connector). Replace the sensor if the meter measures resistance less than 10 ohms of resistance. The meter should measure 84,925 ohms if the sensor temperature is 0 degrees, 32,566 ohms at 32 degrees and 11,304 ohms at 72 degrees (room temperature). Measure the resistance of the sensor using a multimeter. Unplug the refrigerator and disconnect the freezer temperature sensor from its wire harness. The freezer temperature sensor connects to the electronic control board through the gray/white wires on the J4A connector. ![]() If the meter measures correct resistance through the sensor, plug the temperature sensor back in and measure resistance through the freezer temperature sensor wires that connect to the electronic control board.
