Utica-Dunkirk 14631000 Rollout Switch
The Utica-Dunkirk 14631000 Rollout Switch is a critical safety component designed for high-limit thermal protection in residential and commercial heating systems. Rated at 300F (148.9°C), this manual reset rollout switch monitors the burner area for flame rollout conditions—typically caused by a cracked heat exchanger or obstructed venting. When excessive heat is detected, the switch interrupts the 24V furnace control circuit to prevent carbon monoxide leaks and fire hazards. This specific OEM replacement part measures approximately 1.55x2.95x1.1 inches, ensuring exact compatibility with several Utica-Dunkirk Q90 series boilers, including the Q90-50, Q90-75, and Q90-100 models. For technicians performing furnace troubleshooting, verifying continuity across the terminals is essential; an open circuit with the button depressed indicates a failed internal bimetal disc requiring immediate furnace part replacement to restore safe unit operation.
Key Benefits- High-Limit Safety: The 300-degree F limit provides a precise thermal cutoff to protect the combustion chamber and surrounding components from heat damage.
- Manual Reset Function: Forces a manual inspection of the heat exchanger and flue pipe before the system can be restarted, ensuring underlying HVAC safety issues are addressed.
- OEM Compatibility: Designed specifically for Utica-Dunkirk equipment, maintaining the original engineering specifications and agency listings of the appliance.
- Durable Construction: Built to withstand the high-ambient temperatures of the burner vestibule without nuisance tripping.
What causes a 300F rollout switch to trip?
A trip is usually triggered by flue gas recirculation or "rollout" due to a blocked vent, soot buildup in the heat exchanger, or a failing inducer motor that cannot maintain proper draft.
Can I bypass this switch for testing?
No technician should ever bypass a rollout safety switch. If the switch is open, it indicates a dangerous condition that must be repaired before the furnace is placed back into service.
How do I know if my 14631000 switch is bad?
Use a multimeter to check for continuity. If the manual reset button is pushed in but you still measure infinite resistance (O.L.) across the terminals, the internal contacts have failed.
