this Single Pole Double Throw (SPDT) switch provides versatile wiring configurations for both normally open and normally closed circuits

Critical Burner Safety: Prevents furnace ignition during flue blockages or mechanical inducer failure

Whether you are dealing with intermittent pilot ignition or standard 24V AC systems

Lennox 80W53 Pressure Switch 323613-751 maintaining system balance without noisyThe Lennox 80W53 Pressure Switch is a critical OEM replacement part engineered for high efficiency furnace applications. This single pole single throw (SPST) switch is factory calibrated to a 0. 68" WC (water column) set point, ensuring precise monitoring of the inducer motor's draft. A failure in this component often results in a sequence of operation lockout, as the control board must verify proper venting before allowing gas valve ignition.
