OEM Carrier Pressure Switch Assembly w/Bracket HK06WC069 for Model PG8MAA036110ACJA

This is the genuine OEM pressure switch assembly with mounting bracket for the Carrier PG8MAA036110ACJA gas furnace. The pressure switch monitors negative pressure created by the draft inducer motor to confirm proper venting before allowing the ignition sequence to proceed. If the switch fails or sticks open, the control board will lock out the furnace — typically before any spark or gas flow occurs — leaving you with a no-heat call and a flashing fault code.

• Specs: Single-stage draft pressure switch | Includes factory mounting bracket | Rated for .27" W.C. break / .42" W.C. max make | Direct OEM replacement for part number HK06WC069
• OEM vs Generic: This is a factory-matched Carrier OEM part with exact W.C. (water column) rating. Aftermarket pressure switches often carry wider tolerances that can cause nuisance lockouts or, worse, allow ignition under unsafe venting conditions — a critical safety risk.
• Install difficulty: 2/5 — Turn off power and gas before beginning. Disconnect the rubber hose from the inducer port and the two wire leads. Unbolt the bracket, swap the switch, and reconnect. Tools needed: 1/4" nut driver, needle-nose pliers. Always inspect the hose for cracks or blockage before installing the new switch.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — order by 3 PM local time for same-day dispatch.
