This OEM Dual Pressure Switch Assembly (part #HK06NB012) is the factory-specified replacement for the Carrier PG92SBS66100CAAA packaged gas furnace. The pressure switch is a critical safety component that monitors the negative pressure (vacuum) created by the inducer motor, confirming that combustion gases are being properly vented before allowing the ignition sequence to proceed. When this switch fails or sticks open, the furnace control board will lock out ignition entirely — leaving you with a blinking fault code, no heat, and a furnace that clicks through a cycle without lighting. This assembly also includes the secondary gas pressure switch (HK02LB008), ensuring the complete dual-switch circuit is restored with a single repair.
Compatibility: Engineered for the Carrier PG92SBS66100CAAA packaged gas furnace. This listing covers both OEM part numbers HK06NB012 (Dual Pressure Switch Assembly) and HK02LB008 (Gas Pressure Switch) as included in the assembly. Always verify your unit's model data plate and existing switch W.C. rating before installation. Our fitment team is available to confirm compatibility — order with confidence or contact us before purchasing.
