Carrier HH680348 Rollout Limit Switch
The Carrier HH680348 Rollout Limit Switch is a critical OEM furnace safety component designed specifically for gas-fired heating systems. This flame rollout switch functions as a fail-safe by monitoring the temperature within the burner compartment. If it detects a rollout condition—where flames escape the heat exchanger and enter the control area—the switch interrupts the electrical circuit to the gas valve, providing immediate overheating protection. This factory-authorized part features a 300°F cut-out temperature and requires a manual reset, ensuring that a technician can diagnose the root cause of the rollout, such as a cracked heat exchanger or flue restriction, before the system resumes operation.
Engineered for high-reliability in demanding environments, this manual reset limit switch is a direct replacement for various Carrier, Bryant, and Payne models. Professional contractors prefer this HVAC rollout sensor due to its precise calibration and anti-tamper design, which prevents bypass or automatic resets during unsafe conditions. Integrating this genuine Carrier replacement part maintains the original safety specifications of the furnace, ensuring consistent performance and system longevity.
Key Benefits:- Precise Thermal Monitoring: High-limit 300°F trip point ensures rapid response to combustion irregularities.
- OEM Compatibility: Designed for an exact fit in Carrier, Bryant, and Payne gas furnaces, including series 359AAV, 58HDV, and PG9MTAV.
- Enhanced Safety Logic: Manual reset mechanism forces manual inspection after a fault, preventing repetitive unsafe ignition cycles.
- Rugged Construction: Durable thermal limit switch housing stands up to high-ambient temperatures near the burner assembly.
How do I know if the flame rollout switch is tripped?
If your furnace blower runs constantly but there is no ignition, the Carrier HH680348 may be tripped. Verify by checking for continuity with a multimeter once the system power is disconnected.
Can I reset the rollout limit switch multiple times?
While the switch is a manual reset type, repetitive tripping indicates a serious combustion or venting issue. Conduct a full heat exchanger and chimney inspection before re-engaging the system.
What causes a 300-degree rollout switch to open?
Common triggers include a soot-clogged heat exchanger, obstructed flue vents, or negative pressure in the mechanical room pulling flames out of the combustion chamber.
