Carrier HH22HA194 Rollout Switch
The Carrier HH22HA194 Rollout Switch is a critical safety component designed for immediate flame rollout detection in Carrier, Bryant, and Payne gas furnaces. This genuine OEM manual-reset switch features a 55-inch capillary tube sensor, allowing for expansive monitoring across the burner box. Engineered to maintain system integrity, the flame rollout limit switch is calibrated to open at 190 degrees Fahrenheit and close at 150 degrees Fahrenheit. As a veteran technician knows, a tripped rollout often signals localized overheating or flue gas backup, requiring a manual reset after the underlying combustion issue is addressed. This SPST furnace safety switch replaces older ICP part numbers HH22HA190, HH22HA192, and HH22HA193, ensuring broad backward compatibility for field repairs. This heavy-duty HVAC rollout sensor prevents dangerous heat buildup by interrupting the heating cycle when temperatures exceed safe operating limits, protecting the heat exchanger and surrounding furnace assembly.
Key Benefits
- Broad Burner Coverage: The 55-inch capillary sensor provides longitudinal thermal monitoring across multiple burner ports.
- Precision Thermal Calibration: Set to open at 190°F and close at 150°F for accurate Carrier furnace troubleshooting and safety.
- Direct OEM Replacement: Replaces ICP and Bryant parts HH22HA190 and HH22HA192 for seamless fitment in existing burner compartments.
- Manual Reset Safety: Forced manual intervention ensures technicians can inspect for cracked heat exchangers or venting obstructions before restarting the system.
Common Questions
How do I know if the Carrier HH22HA194 needs to be replaced?If you have verified there are no venting blockages or heat exchanger cracks and the switch remains open (infinite resistance on a multimeter) after attempting a manual reset, the internal bimetal or capillary fluid has likely failed.
Why does this rollout switch have a 55-inch capillary?The extended capillary is designed to wrap around or span across the burner assembly, detecting flame rollout at any point along the heat exchanger inlet rather than at a single fixed point.
Can this switch be used in Payne high-efficiency furnaces?Yes, the HH22HA194 is a standard furnace flame rollout switch replacement for many Carrier-family brands, including Payne and Bryant, provided the temperature ratings and capillary length match the original specifications.
