Utica-Dunkirk 27067 Limit Switch
The Utica-Dunkirk 27067 Limit Switch is a critical safety component engineered for precise thermal regulation within residential heating systems and commercial HVAC equipment. This L200-40F 7-inch limit switch features a normally closed SPST snap-disc configuration, designed to open the circuit at a 200°F set point and automatically reset once the temperature drops by 40°F. As a seasoned technician, you know that furnace high limit switch replacement requires a component that can handle the high-cycle demands of modern heat exchangers. This OEM-spec part, often cross-referenced as L200-40F 83L78, utilizes a 7-inch insertion probe to ensure accurate sensing deep within the plenum, preventing heat exchanger overheating and potential equipment damage. Whether you are addressing a furnace short cycling issue or a complete system lockout, this 7" probe limit switch provides the reliability needed for high-temperature limit control in Utica and Dunkirk boilers or furnaces.
Key Benefits:
- OEM Compatibility: Exact drop-in replacement for the Utica-Dunkirk 27067, maintaining original engineering specifications.
- Automatic Reset Logic: Eliminates manual intervention by resetting automatically at 160°F, reducing nuisance service calls.
- Precision Sensing: The 7-inch probe length allows for optimal placement in the airflow path for faster response times.
- Industrial Build: Features a robust ceramic and metal housing to withstand the rigors of HVAC thermal cycling.
Common Questions:
Is this switch compatible with other brands?
While designed for Utica and Dunkirk equipment, the L200-40F 7" limit switch is a standard 1/2-inch snap-disc style often found in Armstrong, Lennox, and Ducane units where the 83L7801 part number is specified.
What are the symptoms of a failing limit switch?
Common indicators include the indoor blower motor running continuously or the furnace burner shutting down prematurely before the thermostat is satisfied, often triggered by restricted airflow or a weak bi-metal disc.
What does the 'L200-40F' designation mean?
Technically, this indicates an "Open on Rise" switch with a cut-out temperature of 200°F and a fixed 40°F differential, meaning it will re-close the circuit at 160°F.
