Description
The Carrier HH12HA163 is a 160°F manual reset limit switch engineered to protect furnace heat exchangers and heating systems from dangerous overtemperature conditions. When supply air temperatures exceed the 160°F setpoint, this limit switch opens the circuit to shut down the burner, preventing equipment damage and potential safety hazards. Because it is a manual reset type, the switch requires a deliberate technician reset before the system can resume operation — ensuring that the root cause of the overtemperature event is identified and corrected before restart.
Designed as a genuine Carrier OEM replacement part, the HH12HA163 delivers a precise fit and reliable performance in compatible Carrier heating equipment, eliminating the guesswork of aftermarket substitutions.
