ensuring the secondary 24V output remains stable for relays and contactors

Because this is a variable speed HVAC motor

Optimized 18" Diameter: Ensures full coverage across the coil surface area for maximum heat transfer

Does it matter which way the wires are connected

the MK-3141 is the official replacement model

Lennox 10J73 Pressure Switch 323613-751 ensuring the secondary 24V outputThe Lennox 10J73 Pressure Switch (Catalog Number 10J73, Model 103827 01) is a critical safety component designed for furnace applications to ensure the inducer motor is moving combustion air effectively. As a single pole, normally open switch, it is calibrated to a fixed set point of 0. 25 PF (inches water column), making it a precise replacement for the combustion air prover in Lennox G21, G24, G27, G28, G30, and G37 series furnaces.
