Carrier HH22HA191 Rollout Switch

The Carrier HH22HA191 is a commercial-grade flame rollout switch engineered to provide critical thermal protection in residential heating systems and light commercial furnaces. This OEM replacement part is a Single Pole Single Throw (SPST) safety device configured to open at 190°F and automatically reset at 150°F once the temperature stabilizes. Designed for high-heat environments, the HH22HA191 rollout switch functions as a fail-safe, interrupting the electrical circuit if a burner malfunction causes flames to "roll out" beyond the heat exchanger combustion chamber. This SPST furnace switch features a 125VA @ 120-227V electrical rating, ensuring seamless HVAC system compatibility with a wide range of Carrier, Bryant, and Payne equipment. Its automatic reset capability reduces downtime for contractors during furnace troubleshooting by restoring the circuit without manual intervention once safe operational limits are restored. This component is essential for maintaining HVAC safety standards and protecting the unit from catastrophic overheating.

• Automatic Reset Mechanism: Resets the circuit at 150 degrees Fahrenheit, eliminating the need for manual service calls after minor temperature fluctuations.
• OEM Compatibility: A genuine Carrier HH22HA191 replacement, ensuring precise fitment for Carrier, Bryant, and Payne furnace models.
• High Thermal Threshold: Calibrated to trip at a 190°F open temperature for reliable detection of flame rollout or restricted airflow.
• Simplified Installation: The SPST configuration and compact mounting footprint allow for rapid field replacement in confined furnace compartments.
• Superior Construction: Built for high-heat industrial and residential applications with a maximum rating of 125VA.

• Does this switch require a manual reset? No, this is an automatic reset rollout switch. It will close the circuit once the component cools to 150°F.
• What happens if my furnace keeps tripping the HH22HA191? Frequent tripping often indicates a blocked vent, cracked heat exchanger, or improper gas pressure; the rollout switch is performing its safety function.
• Which brands are compatible with this part? This part is designed for systems manufactured under the Carrier Corporation umbrella, including Bryant, Payne, and ICP equipment.
