OEM Carrier LP Gas Pressure Switch for Model PG8JAA036070AFJA

This is the factory OEM LP (propane) gas pressure switch for the Carrier PG8JAA036070AFJA packaged gas unit. The pressure switch monitors the negative pressure produced by the inducer motor to confirm safe combustion airflow before allowing the gas valve to open. When this switch fails or sticks open, the furnace will lock out on the first call for heat — often with no error code or with a pressure switch fault code — leaving you without heat until the root cause is resolved.

• Specs: LP (propane) gas pressure switch | 6.5" W.C. cut-out set point | SPST normally-open configuration | Replaces OEM part numbers HK02LB008, HK06WC091, and HK06WC100 (bracket version)
• OEM vs Generic: OEM switches are factory-calibrated to the exact W.C. rating for your unit. Off-spec generic switches can trip too early or too late, causing nuisance lockouts or unsafe operation. Always verify the W.C. rating matches your unit's data plate.
• Install difficulty: 2/5 — Shut off power and gas before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a manometer (recommended to verify set point post-install). Note: HK06WC100 variant includes a mounting bracket — confirm your installation needs before ordering.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility Note: Designed for the Carrier PG8JAA036070AFJA packaged gas/electric unit.
