2. Safety Information

Always prioritize safety when working with electrical components and refrigeration equipment. Failure to follow safety instructions can result in property damage, personal injury, or death.

• Disconnect Power: Ensure the refrigeration unit is completely disconnected from its power source before attempting any installation, maintenance, or repair.
• Qualified Personnel: Installation and service should only be performed by qualified and experienced technicians.
• Personal Protective Equipment (PPE): Wear appropriate PPE, including safety glasses and gloves, during installation and handling.
• Electrical Connections: Verify all electrical connections are secure and conform to local electrical codes.
• Component Handling: Handle the temperature control carefully to avoid damage to the capillary tube or electrical terminals.

3. Setup and Installation

This section outlines the general steps for replacing an existing temperature control. Specific procedures may vary depending on the refrigeration unit model. Refer to your unit's service manual for detailed instructions.

1. Power Disconnection: Turn off and unplug the refrigeration unit from the main power supply.
2. Access Panel Removal: Locate and remove the access panel that covers the existing temperature control.
3. Document Connections: Before disconnecting, carefully note or photograph the wiring connections to the old temperature control. This will aid in correct re-installation.
4. Disconnect Wiring: Carefully disconnect all wires from the old temperature control.
5. Remove Capillary Tube: Gently uncoil and remove the capillary tube from its sensing location. Be careful not to kink or damage the tube.
6. Remove Old Control: Unscrew or unclip the old temperature control from its mounting bracket.
7. Install New Control: Mount the new True 800366 Temperature Control in the same location using the provided screws or existing hardware.
8. Route Capillary Tube: Carefully route the new capillary tube to the sensing location, ensuring it is not pinched or damaged. Secure it as per the original installation.
9. Connect Wiring: Reconnect the electrical wires to the new temperature control, matching the connections documented in step 3. Ensure all connections are tight and secure.
10. Secure Access Panel: Replace the access panel.
11. Restore Power: Plug the refrigeration unit back into the power supply and turn it on.

4. Operation

The True 800366 Temperature Control regulates the internal temperature of your refrigeration unit. It operates by sensing the temperature via its capillary tube and cycling the compressor on and off to maintain the desired setting.

• Temperature Adjustment: The control features an adjustment knob or shaft. Rotate this knob to set the desired temperature. Typically, rotating clockwise decreases the temperature (makes it colder), and counter-clockwise increases it (makes it warmer).
• Initial Startup: After installation, allow the unit several hours to reach the set temperature. Avoid frequently opening the doors during this period.
• Monitoring: Periodically monitor the internal temperature with a separate thermometer to ensure the control is functioning correctly and maintaining the desired range.

5. Maintenance

The True 800366 Temperature Control is designed for durability and reliability. Regular maintenance of the overall refrigeration unit is crucial for its performance, but specific maintenance for the control itself is minimal.

• Visual Inspection: Periodically inspect the control and its wiring for any signs of wear, corrosion, or loose connections.
• Capillary Tube Integrity: Ensure the capillary tube remains securely in its sensing location and is free from kinks or damage.
• Cleaning: If necessary, gently wipe the exterior of the control with a dry, soft cloth. Do not use liquid cleaners directly on the electrical components.

6. Troubleshooting

If your refrigeration unit is not maintaining the correct temperature after replacing the control, consider the following common issues:

For complex issues or if troubleshooting steps do not resolve the problem, it is recommended to contact a certified refrigeration technician.
