Description
The Nordyne 632492R is an OEM replacement SPST (Single-Pole, Single-Throw) pressure switch engineered for precise draft and combustion air proving in Nordyne-brand heating systems. Rated at -0.50″ WC (water column), this switch monitors negative pressure levels within the venting and inducer circuit, opening or closing the control circuit only when the correct pressure differential is achieved — helping protect the heat exchanger and ensure safe, efficient furnace operation.
