Description
The Carrier HH22HA236 is a factory authorized OEM manual reset rollout (limit) switch designed to enhance safety in gas furnaces by detecting dangerous flame rollout or overheating. This part helps shut off the furnace when internal temperatures climb above a safe threshold — protecting your equipment and your home.
Key Features
- High Temperature Protection: Rated to trip at approximately 225 °F, this switch prevents overheating and minimizes the risk of flame rollout.
- Manual-Reset Operation: Once triggered, the switch must be manually reset to restore operation — offering deliberate protection after a fault.
- SPST Design: Single-pole, single-throw configuration for reliable circuit control.
- Durable Build: Constructed with high-quality materials to endure repeated thermal cycling and long-term furnace operation.
- OEM Fit: Designed by Carrier to match compatibility requirements for many Carrier, Bryant, and Payne furnace models — ideal for replacement of the original limit switch.
- Compact Size: Lightweight with a form factor that fits easily into most furnace housings.
