Carrier HH19ZA150 Limit Switch 320819-301 the mechanical assembly is compromisedThe Carrier HH19ZA150 Limit Switch is a critical OEM safety control designed to monitor discharge air and heat exchanger temperatures in Carrier, Bryant, and Payne furnaces and air handlers. This auto reset high limit switch is engineered with a pre set trip point that opens at 150F to interrupt the burner circuit or blower motor, preventing hazardous overheating. Once the internal temperature closes at 110F during the cooling cycle, the switch
