OEM Carrier Pressure Switch with Bracket HK06WC100 for Model PG8JEB036070AAJA

This is the factory OEM draft inducer pressure switch with mounting bracket for the Carrier PG8JEB036070AAJA gas furnace. The pressure switch is a critical safety device that monitors negative pressure created by the inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or its sensing hose cracks, the control board will not advance past the inducer stage — resulting in a no-heat lockout condition, often indicated by a diagnostic fault code for a "stuck open pressure switch."

• Specs: -0.27" W.C. break pressure | 0.42" W.C. max make | SPST (Single Pole, Single Throw) | Includes factory mounting bracket | OEM Part: HK06WC100 (superseded to HK06MC100)
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, calibrated to the exact W.C. rating required by the PG8JEB036070AAJA. Aftermarket switches often carry wider pressure tolerances that can trigger nuisance lockouts or, worse, fail to detect a true venting fault — a potential safety risk.
• Install difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" nut driver, needle-nose pliers. Disconnect the rubber sensing hose and two-wire harness, unmount the bracket, and reverse steps with the new switch. Always inspect the sensing hose for cracks or blockage before assuming the switch is faulty.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
