Installation Instructions

This section outlines the general steps for replacing a refrigerator/freezer thermostat. Specific procedures may vary depending on your appliance model. Refer to your appliance's service manual for detailed instructions.

1. Disconnect Power: Unplug the refrigerator/freezer from the wall outlet to ensure no electrical current is flowing.
2. Access the Thermostat: Locate the existing thermostat. This is typically found near the temperature control dial, often behind a control panel or inside the refrigerator compartment. You may need to remove shelves, drawers, or plastic covers.
3. Document Wiring: Before disconnecting any wires, take clear photos or make a diagram of the existing wiring connections to the thermostat. Note the position of each wire.
4. Remove Old Thermostat: Carefully disconnect the electrical wires and detach the capillary tube from its mounting clips or housing. The capillary tube's end (sensor bulb) is usually inserted into a specific location within the evaporator or cold plate to sense temperature. Remove the old thermostat from its mounting bracket.
5. Install New Thermostat: Mount the new Liebherr K59 L2686 thermostat in the same location as the old one. Connect the electrical wires exactly as they were on the old thermostat, referring to your photos or diagram.
6. Position Capillary Tube: Carefully route and secure the new capillary tube in the identical position as the old one. Ensure the sensor bulb is correctly placed in its designated sensing area. Avoid sharp bends or kinks in the tube.
7. Reassemble: Replace all covers, shelves, and drawers that were removed.
8. Restore Power: Plug the refrigerator/freezer back into the wall outlet.
9. Test Operation: Set the temperature control to a desired setting and monitor the appliance's operation to ensure it cools correctly and cycles on and off as expected.

Operation

The K59 L2686 thermostat is an automatic component that regulates the temperature within your refrigerator or freezer. Once installed, its operation is integrated with your appliance's temperature control dial.

• Temperature Control: Adjust the temperature setting using your appliance's external or internal temperature control dial. The thermostat will then automatically switch the compressor on and off to maintain the set temperature.
• Defrost Cycle: This thermostat also plays a role in initiating the defrost cycle in frost-free models, ensuring efficient operation and preventing ice buildup.

Maintenance

The thermostat itself is a sealed unit and requires no routine maintenance.

• Regular Cleaning: Ensure the area around the thermostat and its capillary tube is kept clean and free from debris to allow for accurate temperature sensing.
• Professional Inspection: If you suspect issues with temperature regulation after installation, consult a qualified appliance technician.

Troubleshooting

If your appliance is not cooling properly or is over-cooling after thermostat replacement, consider the following:

• No Power: Check if the appliance is plugged in and the circuit breaker has not tripped.
• Incorrect Wiring: Double-check all electrical connections against your wiring diagram or photos taken during removal. Ensure all terminals are securely connected.
• Capillary Tube Placement: Verify that the capillary tube is correctly positioned in its sensing location and is not kinked or damaged. Improper placement can lead to inaccurate temperature readings.
• Door Seals: Inspect door seals for any gaps that might allow warm air to enter, affecting temperature.
• Ventilation: Ensure the condenser coils are clean and there is adequate airflow around the appliance.
• Other Components: If the issue persists, the problem might lie with other components such as the compressor, fan motor, or defrost system. Professional diagnosis is recommended.
