Description
The Nordyne 632614 is a factory-specified dual pressure switch engineered for use in Nordyne heating systems. Designed to monitor two distinct pressure set points — .40″ W.C. and .70″ W.C. — this switch plays a critical role in safeguarding furnace operation by verifying proper draft and combustion airflow before and during burner ignition.
How It Works
Dual pressure switches simultaneously monitor negative pressure at two points in the venting and inducer circuit. If either pressure threshold is not met — indicating a blocked flue, failed inducer motor, or restricted vent — the switch interrupts the ignition sequence, preventing unsafe furnace operation and protecting the heat exchanger from damage.
