OEM Carrier Dual Pressure Switch Assembly HK06NB021 for Model PG95XAT60100CBAA

This OEM dual pressure switch assembly is the factory-specified replacement for the Carrier PG95XAT60100CBAA 95% AFUE gas furnace. The pressure switch is a critical safety component that monitors the inducer motor's vacuum pressure to confirm proper draft and safe flue gas venting before allowing ignition to proceed. When this switch fails or sticks open, the furnace control board will lock out the heating sequence — typically before the igniter ever fires — leaving you with a cold home and a blinking fault code. Common symptoms include the inducer motor running but the furnace never advancing to ignition, a pressure switch fault code on the control board, or repeated short-cycling with no heat output.

• Part Numbers: OEM part HK06NB021 (superseded by HK06MB021) | Honeywell cross-reference BA20268-2 | Dual-switch assembly with both switches included, each featuring 2 wire terminals and 1 hose port
• OEM vs Generic: This is a genuine Carrier OEM assembly, factory-matched to the exact water column (W.C.) rating required by the PG95XAT60100CBAA. Aftermarket switches often carry wider W.C. tolerances that can allow unsafe venting conditions or nuisance lockouts — don't compromise on a safety part.
• Install Difficulty: 2/5 — Power down the furnace and disconnect 24V control wiring before starting. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers. Label all hose and wire connections before removal. Swap hoses one at a time to avoid mis-routing. No special tools required.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered for the Carrier PG95XAT60100CBAA 95% AFUE two-stage gas furnace.
