OEM Carrier Pressure Switch with Bracket -0.27" W.C. for Model PG8JEB060110AAJA

This OEM draft inducer pressure switch with mounting bracket is the factory-specified replacement for the Carrier PG8JEB060110AAJA gas furnace. The pressure switch monitors negative pressure created by the inducer motor to confirm safe draft before allowing ignition. When it fails or sticks open, the furnace control board will not advance past the inducer pre-purge stage, resulting in a no-heat lockout — often with a 3-flash or pressure-switch fault code on the control board.

• Specs: Set point -0.27" W.C. (break) | 0.42" W.C. max make | SPST normally-open | Includes factory mounting bracket | OEM Part: HK06WC100 (superseded by HK06MC100)
• OEM vs Generic: This is a genuine Factory Authorized Part manufactured to Carrier's exact W.C. rating tolerance. Aftermarket pressure switches with off-spec set points can cause nuisance lockouts or, worse, unsafe ignition sequencing.
• Install difficulty: 2/5 — Shut off power and gas before beginning. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers. Disconnect the rubber hose from the inducer port, unplug the wiring harness connector, and swap the bracket-mounted switch. Always check the hose for cracks or blockage before installing the new switch.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse.
