Description
The Nordyne 632547R is a genuine OEM Single-Pole Single-Throw (SPST) pressure switch engineered to a precise set point of -0.90″ Water Column (WC). Designed as a direct-fit replacement for compatible Nordyne furnace and air handler models, this pressure switch plays a critical role in safe system operation by monitoring the negative pressure produced by the draft inducer motor.
How It Works
The pressure switch continuously monitors the pressure differential within the combustion air circuit. If the draft inducer fails to establish or maintain the required negative pressure, the switch interrupts the control circuit, preventing ignition and protecting against hazardous flue gas conditions. This safeguard is essential for maintaining safe and efficient furnace operation.
