The pressure switch monitors negative pressure created by the inducer draft motor to confirm safe venting conditions before allowing ignition to proceed. When this switch fails — or when the inducer is unable to generate sufficient draft — the control board receives no signal and the system locks out before the igniter even fires. Common symptoms include a furnace or packaged unit that runs the inducer but never advances to ignition, a blinking fault code indicating a pressure switch error, or a unit that attempts ignition repeatedly and then shuts down entirely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Rated for low-voltage control circuit (24V) | W.C.

Generic switches frequently carry wider tolerances, risking nuisance lockouts or — more critically — allowing ignition under unsafe draft conditions. OEM is always recommended for gas appliance safety components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Turn off power and gas before servicing.
