6. Install Capillary Tube: Carefully route the new 36-inch capillary tube to the original sensing location within the appliance. Ensure the tube is not kinked or damaged during installation. The tip of the capillary tube is where temperature is sensed.
7. Connexions de cable: Connect the electrical wires to the new control unit's terminals, matching the configuration documented from the old unit. Use the provided 1/4-inch T-connectors for secure connections if needed. Ensure all connections are tight and properly insulated.
8. Attach Dial: Slide the black temperature adjustment dial onto the D-stem shaft of the control unit.
9. Assegurar i provar: Close any access panels. Restore power to the appliance. The unit should now be ready for operation.

5. Funcionament

The Mavrik 077B7061 temperature control unit is operated via its front-mounted dial. The dial features settings from 1 to 9, with 'Colder' indicating a lower temperature setting.

• Ajust de temperatura: Rotate the dial clockwise for colder temperatures (higher numbers) and counter-clockwise for warmer temperatures (lower numbers).
• Configuració inicial: For initial setup, it is recommended to start at a mid-range setting (e.g., 5) and adjust gradually based on the desired cooling performance and actual temperature readings within the appliance.
• Fluctuació de la temperatura: Allow sufficient time for the appliance's internal temperature to stabilize after any adjustment before making further changes.

6. Manteniment

Regular maintenance helps ensure the longevity and optimal performance of your temperature control unit.

• Neteja: Periodically clean the exterior of the control unit and the dial with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Capillary Tube Inspection: Ensure the capillary tube remains securely in its sensing location and is free from kinks, damage, or corrosion.
• Connexions elèctriques: Annually, with power disconnected, inspect electrical connections for tightness and signs of corrosion.

7. Solució De Problemes

If the appliance is not maintaining the desired temperature, consider the following common issues:

• Sense energia: Check if the appliance is plugged in and if the circuit breaker has tripped.
• Incorrect Dial Setting: Ensure the temperature dial is set to the desired cooling level.
• Capillary Tube Placement: Verify the capillary tube is correctly positioned in the temperature sensing area and is not dislodged or damaged.
• Airflow Obstruction: Ensure there is adequate airflow around the appliance's cooling coils and that vents are not blocked.
• Segells de portes: Check appliance door seals for leaks, which can lead to temperature fluctuations.

If these steps do not resolve the issue, it is recommended to consult a qualified appliance technician.
