Nordyne 632516R Pressure Switch 321042-401 replacing a restricted or failed

replacing a restricted or failed valve with this Carrier replacement TXV ensures the system operates within its original factory specifications

This valve is designed for low-pressure systems and is rated for a maximum of 0

preventing the escape of combustion byproducts and ensuring consistent manifold pressure

Optimized Signal Distribution: Restores proper communication between the ICB (Integrated Control Board) and fan motors or gas valves

A NEMA 1 rating is intended for indoor use to provide basic protection against contact

Nordyne 632516R Pressure Switch 321042-401 replacing a restricted or failedThe Nordyne 632516R Pressure Switch is the direct engineering update for the legacy 632516 model, designed specifically for high efficiency gas furnaces within the Miller, Intertherm, and Nordyne families. This dual circuit 0. 50" PF 0. 40" PF differential switch monitors the pressure within the inducer housing and heat exchanger, ensuring the combustion process remains within safe operating parameters before allowing the ignition sequence to proceed.
