OEM Carrier Pressure Switch with Bracket .33" W.C. for Model PG8DAA024050ACJA

This is the factory OEM replacement pressure switch with mounting bracket for the Carrier PG8DAA024050ACJA packaged gas furnace. The pressure switch is a critical safety device that monitors negative pressure created by the inducer motor before allowing the ignition sequence to proceed. When it fails or sticks open, your furnace will lock out before ignition — leaving you without heat. Common symptoms include a blinking fault code indicating a pressure switch fault, the inducer running but the furnace never advancing to ignition, or the system continuously recycling through the startup sequence without firing.

• Specs: .33" W.C. (water column) rating | Includes mounting bracket | Direct OEM replacement | Replaces superseded part numbers HK06WC086, HK06WC088, HK06WC072, HK06WC073, HK06WC074, HK06WC076
• OEM vs Generic: This is a genuine Carrier OEM part calibrated to the exact .33" W.C. trip point for the PG8DAA series. Generic aftermarket switches often carry looser pressure tolerances, which can result in nuisance lockouts or — worse — unsafe ignition attempts.
• Install difficulty: 2/5 — Power off the furnace at the disconnect before beginning. Tools needed: flathead screwdriver, needle-nose pliers, and a phone or camera to photograph hose and wiring connections before removal. Inspect the rubber pressure hose for cracks while the switch is out — a cracked hose is a common companion failure.
• Warranty: 1-year OEM manufacturer warranty from date of purchase. Orders placed by 5 PM EST ship same business day from our warehouse.

Compatibility: Engineered for the Carrier PG8DAA024050ACJA packaged gas furnace unit. This part also cross-references to legacy Carrier, Bryant, and Payne units previously serviced with HK06WC086 or HK06WC088. Always verify the .33" W.C. rating on your unit's existing switch or service manual before ordering. Have a fitment question?
