The pressure switch is a critical safety component that monitors the negative pressure (vacuum) generated by the draft inducer motor. Before allowing the ignition sequence to begin, it verifies the inducer is spinning at the correct RPM and that the flue pathway is clear. When this switch fails or sticks open, the furnace control board will lock out the system — typically before a single ignition attempt — leaving you with no heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e SPST (Single-Pole, Single-Throw) | High-Fire configuration | Factory Authorized Part manufactured by Honeywell | Designed to Carrier factory vacuum set-point specifications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM switch is calibrated to the exact water-column (W.C.) set-point for the PG8JAA060155AAJA. Generic aftermarket switches frequently ship with incorrect W.C. ratings or wider tolerances, which can cause nuisance lockouts or — more dangerously — allow the furnace to operate with inadequate flue draft.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Power down the furnace and confirm zero voltage at the board before beginning.
