Carrier HH12ZZ165 Limit Switch 323055-751 it can technically serve asThe Carrier HH12ZZ165 Limit Switch is a critical OEM safety component engineered for precision thermal monitoring in HVAC furnaces and industrial heating systems. As a fixed temperature L165F 40 limit control, this switch features a normally closed (NC) circuit designed to open on a temperature rise at its 165F set point, effectively preventing heat exchanger damage. With a 40F differential, the automatic reset engages when the internal temperature
