OEM Carrier Dual Pressure Switch Assembly HK06NB012 & HK02LB008 for Model PG92SBS66100CBAA

This OEM pressure switch kit is the factory-specified replacement for the Carrier PG92SBS66100CBAA 92% AFUE packaged gas furnace. The kit includes two critical safety switches: the HK06NB012 Dual Air Pressure Switch Assembly, which proves that the inducer motor is running at the correct RPM and generating sufficient draft vacuum before allowing ignition, and the HK02LB008 Gas Pressure Switch, which monitors gas line pressure to ensure safe combustion conditions. When either switch fails, the furnace control board will lock out ignition — typically displaying a fault code and resulting in no heat. Common failure symptoms include the inducer motor running but ignition never initiating, or the furnace cycling off within seconds of startup.

• Kit Includes: HK06NB012 Dual Air Pressure Switch Assembly + HK02LB008 Gas Pressure Switch | Both switches include 2 wire terminals and one hose port each | Factory-matched W.C. (water column) setpoints for model PG92SBS66100CBAA
• OEM vs Generic: OEM pressure switches are factory-calibrated to exact W.C. trip points. Aftermarket substitutes often carry wider tolerances, risking nuisance lockouts or — more critically — failing to detect a true inducer fault, which can allow unsafe flue gas conditions.
• Install Difficulty: 3/5 — Turn off gas supply and 120V power before servicing. Tools needed: 1/4" & 5/16" nut drivers, needle-nose pliers, manometer (recommended to verify W.C. after install). Photograph all hose and wiring connections before disconnecting. Clear any fault codes after installation.
• Warranty: 1-year OEM factory warranty on both switches. Orders placed before 3 PM local time ship same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PG92SBS66100CBAA packaged gas furnace.
