Carrier HH18HA201 Limit Switch 320788-702 The Nordyne 669772 TXV isThe Carrier HH18HA201 Limit Switch is a critical safety component designed for precise thermal monitoring within furnace heat exchangers and air handlers. Engineered as a 160 degree furnace limit switch, this L160 40 thermally actuated control prevents equipment overheating by breaking the electrical circuit when the internal temperature exceeds the 160F fixed setpoint. It features a 40F differential, ensuring the system resets once temperatures
