The pressure switch is a critical safety component that monitors negative air pressure created by the inducer motor to confirm proper venting before allowing ignition to proceed. When the switch fails or becomes stuck open, the control board cannot verify safe venting conditions — resulting in a no-heat lockout, fault codes, or a system that attempts ignition and immediately shuts down without ever firing the burners.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Low pressure switch | OEM part number 312926-258 | Factory-calibrated W.C.
