OEM Carrier LP Gas Pressure Switch HK02LB008 / HK06WC091 for Model PG8JAA024070AFJA

This OEM gas pressure switch is the factory-specified replacement for the Carrier PG8JAA024070AFJA packaged gas unit. The pressure switch monitors manifold or inlet gas pressure and opens or closes the control circuit when pressure reaches the factory-set cutout point — protecting the heat exchanger and confirming safe gas flow before the ignition sequence proceeds. When this switch fails, the furnace will typically lock out before ignition, display a pressure-fault error code, or fail to advance past the inducer pre-purge stage entirely.

• Specs: LP (Propane) Gas Pressure Switch | Cutout set point: 6.5" W.C. | SPST normally open | OEM part numbers: HK02LB008 (primary) and HK06WC091 (secondary/cross-reference) | Fits Carrier, Bryant, and Payne equipment
• OEM vs Generic: This is a factory OEM part manufactured to exact pressure-setpoint tolerances. Generic aftermarket switches are frequently calibrated ±15% or more off-spec, which can cause nuisance lockouts, unsafe gas pressure conditions, or premature heat exchanger failure.
• Install difficulty: 2/5 — Shut off gas supply and power before beginning. Tools needed: 1/4" nut driver, flat-head screwdriver, slip-joint pliers. Note wire terminal positions before disconnecting. Inspect rubber hose port and tubing for cracks before reinstalling. Always verify gas pressure with a manometer after replacement.
• Warranty & Shipping: 1-year OEM factory warranty. In stock and ships same business day from our warehouse — order by 3 PM local time for same-day dispatch.

Compatibility: Verified fit for Carrier model PG8JAA024070AFJA packaged gas unit. Also cross-references to Bryant and Payne platforms sharing the same pressure switch specification. Confirm your unit's fuel type (LP/Propane) and W.C. rating on the data plate before ordering — natural gas variants require a different switch. Have questions about fitment?
