The pressure switch monitors negative pressure created by the inducer motor to confirm that combustion airflow is adequate before allowing the ignition sequence to proceed. When this switch fails — or when the hose, port, or inducer is compromised — the control board detects an open switch circuit and locks out heating, leaving you with a furnace that attempts a call for heat but shuts down before the burners ever light.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Closes at \u003cstrong\u003e-0.22\" W.C.

Aftermarket pressure switches frequently carry wider setpoint tolerances that can cause nuisance lockouts in cold weather or, worse, allow the furnace to fire under unsafe draft conditions. OEM is the correct choice for this safety-critical component.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Power down and confirm zero voltage at the board before beginning. Tools needed: 1\/4\" nut driver, flat-blade screwdriver, manometer (to verify port pressure if lockout persists after replacement).
