OEM Carrier Gas Pressure Switch HK02LB008 / HK06WC091 for Model PG8JEA060110ACJA

This OEM Carrier gas pressure switch is the factory-specified replacement for the Carrier PG8JEA060110ACJA packaged gas furnace. The pressure switch monitors the negative pressure created by the draft inducer motor to confirm safe venting conditions before allowing the ignition sequence to proceed. When the switch fails — or its hose, port, or diaphragm degrades — the furnace will lock out before ignition, typically with a fault code indicating a failed pressure switch or open pressure switch circuit. This listing covers OEM part numbers HK02LB008 (Gas Pressure Switch) and HK06WC091 (Pressure Switch), both factory-authorized for this model.

• Specs: SPST normally-open pressure switch | Set point: 6.5" W.C. | Suitable for natural gas and LP/propane applications | Horizontal or vertical mount | Honeywell-manufactured Factory Authorized Part
• OEM vs Generic: OEM pressure switches are calibrated to the exact W.C. set point required by your furnace's inducer design. Off-spec generics with loose tolerances can allow unsafe ignition attempts or nuisance lockouts, voiding equipment warranties.
• Install difficulty: 2/5 — Disconnect power and gas before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, replacement hose (inspect while you're in there). Always confirm the pressure port and hose are clear before condemning the switch — a plugged hose is a common misdiagnosis.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
