Utica-Dunkirk 14629002 Switch

The Utica-Dunkirk 14629002 Switch is a critical safety component designed for high-performance residential and commercial boilers. As a 144c/291f Thermal Cutoff Rollout device, this fixed-temperature limit switch acts as a secondary safety measure, monitoring the burner vestibule for flame rollout conditions. When temperatures exceed the 291°F threshold, the internal thermal fuse opens the electrical circuit, immediately halting gas valve operation to prevent heat damage to the internal cabinet and surrounding structures. This OEM replacement part is specifically engineered for precision and reliability in Utica and Dunkirk BS2AAN and BW3AAN series boilers. Because this is a single-use rollout switch, it requires a full replacement once tripped to restore unit operation. For contractors, maintaining a 14629002 rollout switch in your service kit ensures minimal downtime during emergency repairs where combustion safety limits have been reached. Always verify the 144C thermal limit is appropriate for the specific furnace or boiler model to maintain factory safety standards.

• Precise Thermal Protection: Operates at a calibrated 291°F (144°C) to provide immediate circuit interruption during flame rollout.
• OEM Compatibility: Guaranteed fit for specific Utica-Dunkirk boiler parts, ensuring the safety of the original equipment design.
• Enhanced System Safety: Prevents catastrophic equipment failure and fire hazards by detecting abnormal heat concentrations in the burner area.
• Durable Construction: Built to withstand the harsh thermal environments of gas-fired heating systems.

Is the 14629002 switch manual reset or single-use?
This is a single-use thermal cutoff. Once the temperature reaches 291°F and the circuit opens, the part must be replaced; it cannot be reset.

What causes this rollout switch to trip?
Tripping is typically caused by a blockage in the heat exchanger, a clogged flue, or improper gas pressure leading to flames backing out of the combustion chamber.

Can I use a universal rollout switch instead of the Utica 14629002?
It is highly recommended to use the exact OEM Utica-Dunkirk 14629002 to ensure the temperature rating and mounting alignment meet the manufacturer's safety specifications.
