OEM Carrier Draft Inducer Pressure Switch for PG8JEA024045ABJA

The pressure switch verifies that your Carrier PG8JEA024045ABJA is venting properly before the burners are allowed to fire. When the draft inducer spins up, it pulls a negative pressure that closes this switch, confirming to the control board that flue gases have a clear path out and combustion air is flowing. If the switch fails to close — or opens mid-cycle — the board blocks ignition to keep flue products from spilling indoors. You'll typically see the inducer running with no ignition, the furnace locking out, persistent short-cycling, or a control-board fault code referencing pressure or venting. A switch stuck open causes no-heat; one stuck closed defeats a vital safety interlock. This OEM switch is calibrated to a precise trip point in inches of water column ("WC) and a normally-open contact arrangement matched to your inducer and vent configuration. That model-specific setpoint is what allows it to function as a true safety device. OEM fitment is essential because pressure-switch setpoints are not generic. A switch with the wrong "WC rating will nuisance-trip on a perfectly healthy furnace or, far more dangerously, fail to open when the flue is actually obstructed — eliminating the protection it exists to provide. Aftermarket units also tend to use lower-grade diaphragms and contacts that drift out of calibration. The OEM part holds Carrier's exact specification for the life of the switch. Install difficulty: 2 of 5. Tools: 1/4" nut driver and needle-nose pliers, with a manometer recommended to confirm the trip point. SAFETY: turn off power at the breaker and shut off the gas before servicing, and seat the rubber pressure hose fully — a cracked or loose tube mimics a bad switch.
