3. Safety Information

Before attempting any installation or repair, please observe the following safety precautions:

• Disconnect Power: Always unplug the refrigerator from the main power supply before beginning any work. Failure to do so can result in electric shock or serious injury.
• Professional Installation: If you are not experienced in appliance repair, it is highly recommended to seek assistance from a qualified technician.
• Handle with Care: The capillary tube of the thermostat is delicate. Avoid bending it sharply or damaging it, as this can affect its functionality.
• Wear Protective Gear: Use appropriate personal protective equipment, such as gloves, to prevent injury.

4. Installation

The following steps provide a general guide for replacing a refrigerator thermostat. Specific procedures may vary depending on your refrigerator model. Always consult your appliance's service manual for detailed instructions.

1. Preparation: Disconnect the refrigerator from the power supply. Empty the refrigerator and freezer compartments.
2. Access the Thermostat: Locate the existing thermostat. This is typically found inside the refrigerator compartment, often near the light assembly or control panel. You may need to remove plastic covers or panels.
3. Disconnect Wiring: Carefully disconnect the electrical wires connected to the old thermostat. Note the position of each wire for correct re-connection. Taking a photograph can be helpful.
4. Remove Capillary Tube: Gently unthread or pull out the capillary tube from its housing. This tube senses the temperature inside the refrigerator.
5. Remove Old Thermostat: Unscrew or unclip the old thermostat from its mounting.
6. Install New Thermostat: Mount the new K59L4091 thermostat in the same position as the old one.
7. Insert Capillary Tube: Carefully insert the new capillary tube into the designated sensing area. Ensure it is fully inserted and positioned correctly to accurately measure temperature.
8. Connect Wiring: Reconnect the electrical wires to the new thermostat according to your previous notes or photographs.
9. Reassemble: Replace any covers or panels that were removed.
10. Test: Plug the refrigerator back into the power supply. Set the thermostat to a medium setting and monitor the refrigerator's temperature to ensure proper operation.

A long, coiled capillary tube extends from the top of the unit, which is essential for temperature sensing within the refrigerator.

5. Operation

The K59L4091 thermostat is designed to maintain the desired temperature within your refrigerator. Once installed, its operation is largely automatic. The thermostat senses the internal temperature via its capillary tube and cycles the compressor on and off to keep the temperature within the set range.

Temperature Adjustment: If your refrigerator has an external or internal temperature control knob, this knob is connected to the thermostat. Turning the knob to a higher number or colder setting will cause the compressor to run more frequently, resulting in a lower temperature. Turning it to a lower number or warmer setting will cause the compressor to run less, resulting in a higher temperature.

Allow several hours for the refrigerator to stabilize after any temperature adjustment.

6. Maintenance

The thermostat itself requires minimal maintenance. However, ensuring the overall cleanliness and proper functioning of your refrigerator can prolong the life of all components, including the thermostat.

• Keep Clean: Regularly clean the interior of your refrigerator to prevent food particles or debris from obstructing air circulation around the thermostat's sensing bulb.
• Check Door Seals: Ensure refrigerator door seals are intact and sealing properly to prevent warm air from entering, which can cause the thermostat to work harder.
• Avoid Overloading: Do not overload the refrigerator, as this can impede air circulation and affect temperature regulation.

7. Troubleshooting

If your refrigerator is not maintaining the correct temperature after thermostat replacement, consider the following:

• Refrigerator Too Warm:
  • Check if the thermostat's capillary tube is correctly positioned and not damaged.
  • Ensure the temperature control knob is set to an appropriate cooling level.
  • Verify that the refrigerator door seals are intact.
  • Confirm that the compressor is running. If not, there may be an issue with the thermostat's electrical connections or other components.
• Refrigerator Too Cold/Freezing Food:
  • Check if the temperature control knob is set too low (too cold).
  • Ensure the capillary tube is not in direct contact with the evaporator coils, which could cause it to sense an artificially low temperature.
• Compressor Not Cycling: If the compressor runs continuously or not at all, and the temperature is incorrect, the thermostat may be faulty or incorrectly wired. Recheck all connections.

If troubleshooting steps do not resolve the issue, consult a qualified appliance technician.
