OEM Carrier Pressure Switch for PG8JVA066135AAJA Package Unit

The pressure switch on your Carrier PG8JVA066135AAJA is the safety device that confirms the inducer motor is pulling proper combustion draft before the unit is allowed to ignite. When the inducer starts, it draws a vacuum through the switch hose; the contacts close and the control board then permits the igniter to glow and the gas valve to open. If the switch is stuck open, leaking, or its port is plugged, the inducer runs but the burners never light — symptoms include no heat with the blower cycling, repeated ignition lockouts, and a pressure-switch fault flashed by the diagnostic LED. Always rule out a clogged condensate trap or cracked hose first. This OEM pressure switch is calibrated to the exact trip point in inches of water column specified for the PG8JVA066135AAJA. That setpoint is load-bearing: it must close at correct draft and open the instant flue flow is restricted. The molded hose port and spade terminals match the factory tubing and wiring for a true plug-in fit. Why OEM: a generic switch with the wrong calibration nuisance-trips a perfectly good unit, or dangerously stays closed during a partial flue blockage, neutralizing the safety it's meant to enforce. Aftermarket diaphragms also drift out of spec sooner. The genuine Carrier switch holds its trip pressure for the unit's service life. Install difficulty: 1 of 5. Tools: 1/4" nut driver and a manometer or magnehelic gauge to verify draft. SAFETY: shut off the unit breaker before touching the wiring, and never jumper or bypass the switch — that defeats flue-blockage protection and can vent combustion gases indoors.
