The pressure switch monitors negative pressure created by the inducer motor to confirm that the flue is properly venting before allowing the control board to advance to the ignition sequence. When this switch fails or sticks open, your furnace will lock out before ignition — typically displaying a fault code indicating a pressure switch failure — leaving you with no heat until the part is replaced.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 1.81\" W.C. set point | SPST (single-pole, single-throw) | Normally open | Includes factory mounting bracket | Manufactured by Honeywell for Carrier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM switch is calibrated to the exact water column rating required by the PG9MAB048060AASA.
