OEM Carrier LP Gas Pressure Switch HK02LB008 / HK06WC091 for Model PG8JAA024070AEJA

This OEM LP gas pressure switch is the factory-specified replacement for the Carrier PG8JAA024070AEJA packaged gas unit. The pressure switch monitors gas supply pressure and opens or closes the electrical circuit when the setpoint is reached, acting as a critical safety device that prevents the furnace from operating outside safe pressure parameters. When this switch fails, the unit will typically enter a lockout condition — refusing to fire or shutting down immediately after ignition attempt — leaving you with no heat until the fault is resolved.

• Specs: LP (Propane) Gas Pressure Switch | 6.5" WC cut-out setpoint | SPST configuration | Replaces OEM part numbers HK02LB008 & HK06WC091 | Compatible with air, natural gas, and LP gas applications | Mountable in horizontal or vertical position
• OEM vs Generic: This is a genuine Carrier OEM pressure switch, factory-calibrated to the exact 6.5" WC setpoint required by your unit. Generic aftermarket switches often ship with loose tolerances that can cause nuisance lockouts or — worse — allow unsafe operating conditions to go undetected.
• Install difficulty: 2/5 — Shut off gas and electrical supply before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a manometer to verify pressure after installation. Photograph all hose and wiring connections before disconnecting. Note: always confirm gas type (LP vs. natural gas) matches the switch specification.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse. Note: HK02LB008 has been superseded — HK02MB008 is the current direct OEM replacement; confirm your unit's part requirement before ordering.

Compatibility: Engineered for the Carrier PG8JAA024070AEJA packaged gas unit. Also fits select Bryant and Payne models using the HK02LB008 or HK06WC091 pressure switch specification — verify your model's data plate and gas type before ordering. Questions about fitment?
