Carrier HH18HA465 Limit Switch 318820-201 Smith power vent unitThe Carrier HH18HA465 is a high precision automatic reset limit switch designed for critical thermal protection in Carrier, Bryant, and Payne furnace applications. Operating as a normally closed switch, this safety component opens the circuit at a fixed high limit temperature of 165F and automatically resets once the induction air temperature drops back to 100F. Engineered for high cycle reliability, the HH18HA465 prevents heat exchanger damage caused
