OEM Carrier LP Gas Pressure Switch 6.5" W.C. for Model PG8JEA060135ABJA

This OEM LP gas pressure switch (part numbers HK02LB008 and HK06WC091) is the factory-specified replacement for the Carrier PG8JEA060135ABJA packaged gas unit. The pressure switch monitors the gas supply pressure during the ignition sequence and proves safe operating conditions before allowing the burners to fire. When this switch fails or drifts out of calibration, the furnace control board receives no proof signal and will lock out the ignition sequence — leaving you with a no-heat call, a flashing fault code, or a system that attempts ignition and immediately shuts down.

• Specs: LP (Propane) Gas Pressure Switch | Cut-out pressure: 6.5" W.C. (inches water column) | SPST normally open | Factory-calibrated set point | Fits Carrier, Bryant, and Payne packaged and split furnace platforms
• OEM vs Generic: This is a genuine Carrier OEM part manufactured to exact factory tolerances. Generic pressure switches frequently carry wider set-point tolerances that can cause nuisance lockouts or, worse, allow the burner to fire outside safe pressure limits — always use OEM on gas-side safety components.
• Install difficulty: 2/5 — Shut off gas supply and 24V control power before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, manometer (recommended to verify inlet gas pressure after replacement). Photograph all wiring and tubing connections before disconnecting. Swap the spade terminals and 1/4" barb hose one at a time to avoid misrouting.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock — ships same business day from our NationalHVACParts.com warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PG8JEA060135ABJA packaged gas unit. Cross-references OEM part numbers HK02LB008 and HK06WC091 — both part numbers are acceptable for this application. Verify LP (propane) fuel type and 6.5" W.C. cut-out rating against your unit's data plate before ordering. Not for use on natural gas configurations requiring a different W.C. rating.
