Carrier HH18HA147 Limit Switch 326010-701 Where is this switch typicallyThe Carrier HH18HA147 Limit Switch is a critical safety component designed for precise thermal monitoring within furnace heat exchangers and air handlers. Engineered as a high limit protection device, this switch is a direct replacement for HH18HA147A and functions by opening the electrical circuit if internal plenum temperatures exceed safe operating parameters. This prevents thermal stress on the heat exchanger and ensures the system operates within
