Kenmore Refrigerator Error Codes

To troubleshoot the issue, start by disconnecting the refrigerator from the power source. Check the connection between the Wi-Fi modem and the display control board. Ensure that the cables are securely connected and there are no loose or damaged wires. If the wired connection appears to be in good condition, but the Wi-Fi connection still does not work, it may be necessary to replace the Wi-Fi modem.

Do not rush to replace the heater, as it may be a problem with the control board. If this is not the case, have the heater checked immediately. Remove all containers, baskets and other items from the refrigerator and unplug it. Remove the front panel of the freezer compartment using a flat-blade screwdriver. Check the evaporator and defrost all heater coils. The heater must be removed with extreme care. Do not put any pressure on the coils. Replace the heater in the refrigerator.

The problem may be caused either by poor wiring or loose connectors. Remove the cover and check the CON6 connector on the main controller board. Make sure that there are no problems with the wiring harness. Check the dispenser’s wiring harness and connections if you find no problems.

Disconnect the freezer sensor from the wiring harness and unplug your refrigerator. Use a multimeter to measure the resistance of the sensor. If the resistance value is less than 10 ohms, it indicates a faulty sensor that needs to be replaced. To ensure that your multimeter is accurately measuring the resistance, reconnect the sensor and measure the resistance across the freezer sensor wires connected to the electronic controller board (gray/white cables on connector J4A). After disconnecting connector J4A from the control board, measure the resistance on the grey and white wires. The reading on the multimeter should correspond to the temperature reading. If the meter correctly measures the resistance of the sensor through the cables, the electronic control panel likely needs to be replaced as it is not accurately detecting the resistance of the sensor. However, if the meter indicates a resistance of fewer than 10 ohms for the sensor wires, the issue lies with the wiring, and it should be inspected for any faults or damage.

Connect the loose plug to the wiring harness. Verify the connection of the wiring harness to the electronic control panel (brown/white, yellow/white, and blue/white cables on J4A; and red/white cable on J4B) by checking the evaporator-fan wiring connections. If electrical connections are intact, it is necessary to replace the evaporator. The electronic control board must be replaced if the problem persists.

After disconnecting the refrigerator from the power supply, check the connections between the user interface board and the electronic control panel. If all wire connections are intact, replace the electronic control panel. If the problem persists, replace the user interface.

Check the condition of the air damper, which controls the airflow in the refrigerator and freezer compartments. If it is damaged, you should replace the damper.

If the wire harness is loose, unplug it and tighten it. If the wire harness is damaged, replace it. If the wire harness in the compartment is in good shape, replace the thermistor.

Unplug your refrigerator and reconnect the wire harness. Replace the damaged wire harness. If the wiring harness functions properly, replace the freezer compartment thermistor.

To diagnose the issue, first, unplug the refrigerator from the power source. Then, inspect the connection between the main control board, the user interface control panel, and the wiring harness. Ensure that all cables are properly connected and there are no loose or damaged wires. After reconnecting any exposed cables, if the connections to the wiring harness are secure, consider replacing the user interface unit. However, if the problem persists, it may be necessary to replace the main control board to resolve the issue.
