Description
The Nordyne 632476R is an OEM replacement SPST (Single Pole, Single Throw) pressure switch engineered for precise draft and combustion airflow monitoring in Nordyne-brand heating systems. Calibrated to a set point of -0.30″ w.c. (water column), this switch is designed to confirm proper inducer operation and safe venting conditions before allowing the furnace to proceed through its ignition sequence — helping prevent unsafe operation due to blocked flue, failed inducer, or cracked heat exchanger.
The 1/4″ barbed port connection ensures a secure, leak-free fit to standard rubber tubing used throughout residential and light-commercial furnace applications. As a direct OEM replacement, the 632476R restores factory-spec performance without modification.
