OEM Carrier Pressure Switch with Bracket -0.27" WC for Model PG8JEB060135AAJA

This OEM draft inducer pressure switch with mounting bracket is the factory-specified replacement for the Carrier PG8JEB060135AAJA gas furnace. The pressure switch monitors negative pressure created by the draft inducer motor to confirm safe flue venting before the control board allows the ignition sequence to proceed. When this switch fails or sticks open, the furnace will lock out on a pressure switch fault — typically displaying a fault code and refusing to attempt ignition — leaving you with no heat. A failed or clogged pressure hose can mimic a bad switch, so always inspect the hose and inducer port before replacing.

• Specs: -0.27" W.C. break set point | 0.42" W.C. max make | SPST configuration | Includes factory mounting bracket | Replaces OEM part numbers HK06WC100 and superseded part HK06MC100
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part manufactured to exact W.C. tolerances. Off-brand switches with imprecise set points can cause nuisance lockouts or — worse — allow the furnace to fire without confirmed draft, creating a safety hazard.
• Install difficulty: 2/5 — Shut off power and gas before servicing. Tools needed: 1/4" nut driver, flat-head screwdriver, and a manometer or magnehelic gauge to verify inducer suction if problems persist. Photograph hose routing before disconnecting. Swap the hose barb connection and bracket screws, then restore power to test.
