Utica-Dunkirk 29662 Limit Switch
When you're out in the field servicing a residential boiler or furnace, having a reliable Utica-Dunkirk 29662 Limit Switch on the truck is essential for ensuring system safety and preventing heat exchanger damage. This L160-20F limit switch is a high-performance, 3/4-inch bimetal disc control designed specifically for HVAC equipment repair. It functions as a critical safety device that opens the circuit on a temperature rise at 160°F and automatically resets when the temperature drops 20°F (closing at 140°F). The snap-action switch design provides crisp, positive contact separation, which is vital for maintaining the integrity of current-carrying components under 120/240 VAC loads. Whether you're dealing with an inducer limit issue or a primary high-limit fault, this OEM replacement part offers the precise thermal response required for Utica and Dunkirk heating systems. Its surface-mount configuration and 1/4-inch quick-disconnect terminals make it a straightforward drop-in for technicians looking for a boiler safety limit that meets strict manufacturer specifications.
Key Benefits for HVACR Technicians:- Precise Thermal Control: Engineered as an L160-20F limit switch, ensuring the system shuts down accurately at 160°F to prevent overheating.
- Automatic Reset Function: Once the ambient temperature reaches the 140°F differential, the switch resets, restoring normal furnace or boiler operation without manual intervention.
- Rugged Bimetal Construction: Features a 3/4-inch snap disc built for durability in demanding air stream or inducer housing environments.
- OEM Compatibility: Specifically designed for Utica-Dunkirk models, ensuring the electrical ratings (up to 25A) and physical footprints match the original 29662 part number.
What does the L160-20F designation mean physically?
The "L" indicates it is a limit control (opens on rise). "160" is the fixed opening temperature in degrees Fahrenheit, and "20F" refers to the temperature differential, meaning the switch will close again 20 degrees below the opening point (140°F).
Can this switch be used in both furnace and boiler applications?
Yes, while commonly found in Utica-Dunkirk boilers, the 29662 limit switch is rated for various HVAC applications where an inducer limit or high-limit safety is required, provided the thermal and electrical specs align with the equipment's data plate.
What are the electrical load limits for this part?
This switch is typically rated for up to 15A at 120VAC and can handle pilot duty applications (125VA), making it robust enough for most standard residential control circuits.
