Carrier HH12ZB260 Limit Switch What causes a limit switchThe Carrier HH12ZB260 Limit Switch is a critical safety component engineered for precise thermal regulation in Carrier, Bryant, and Payne furnaces. This auto reset limit switch features a Normally Closed (NC) configuration, designed to break the electrical circuit when the plenum temperature reaches its 260F opening setpoint. Once the heat exchanger cools to the 220F closing temperature, the SPST (Single Pole Single Throw) switch automatically resets,
