York 2SD04700624 Detector Kit 322027-701 this SPST (Single Pole Single

this SPST (Single Pole Single Throw) switch monitors the pressure differential within the combustion chamber to ensure the inducer motor is moving sufficient air for safe ignition

It is standard practice to replace both simultaneously to ensure uniform pressure across the packing rings

it ensures the safe removal of combustion gases and maintains proper static pressure for system ignition

Replacing with a genuine HH22HB067 solves these issues if the switch has drifted out of calibration

It serves as a superior technical cross-reference for the VA-4233-AGA-2
