It is frequently sourced for Carrier furnace door switch replacement in Bryant and Payne 58-series models where the cabinet interlock requires a high-amperage switch

it is intended to slide into different well sizes commonly found in legacy installations to provide a snug fit for the sensing bulb

The limiter is primarily designed to restrict the total stroke of the Belimo LF by providing a physical stop on the housing

this L175-40F manual reset control is engineered to interrupt the burner circuit if heat exchanger temperatures exceed the 175°F safety threshold

For systems requiring a higher amperage draw

York S1-025-27792-708 Limit Switch It is frequently sourced forThe York S1 025 27792 708 is a high precision 170F M R Limit Switch engineered for critical high limit protection in residential and light commercial HVAC furnaces. As a safety critical auxiliary limit switch, this manual reset component monitors internal heat exchanger temperatures, providing a fail safe cutoff to prevent dangerous overheating if airflow is restricted or the primary limit fails to trip. Designed to fit York P2DPD12N06401A models and
