OEM Carrier Dual Pressure Switch Assembly HK06NB020 for Model PG95XAT60080CAAA

This factory OEM dual pressure switch assembly (part HK06NB020) is the direct-fit replacement for the Carrier PG95XAT60080CAAA 95% AFUE two-stage gas furnace. The pressure switch is a safety device that monitors negative pressure generated by the inducer (draft) motor to confirm proper venting before allowing the ignition sequence to proceed. A failed pressure switch is one of the most common causes of furnace lockout — the board detects an open switch circuit and halts all ignition attempts, leaving your home without heat. If your furnace is faulting before the igniter ever glows, or you're getting a pressure switch fault code on the control board, this assembly is the primary suspect.

This listing includes compatibility with supplemental gas pressure switch HK02LB008, a secondary LP/propane gas pressure switch used in some PG95X configurations.

• Specs: Dual-stage pressure switch assembly | Factory W.C. (water column) rating matched to PG95XAT60080CAAA inducer | SPST normally-open contacts | Fits 80,000 BTU, two-stage configuration
• OEM vs Generic: OEM switches carry exact W.C. trip-point calibration from the factory. Off-brand switches frequently use ±15% W.C. tolerance, causing nuisance lockouts in cold weather or premature closure during marginal venting conditions — potentially masking a real venting hazard.
• Install difficulty: 2/5 — Power down and lock out the furnace before starting. Disconnect the rubber hose port and two wiring terminals. Note polarity markings before removal. Tools needed: flathead screwdriver, needle-nose pliers, manometer (to verify W.C. on reinstall). Job typically takes under 20 minutes for an experienced tech.
• Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse.

Compatibility: Designed for the Carrier PG95XAT60080CAAA 95% AFUE two-stage packaged gas furnace. Also cross-references successor part HK06MB020 where applicable. Verify your unit's data plate BTU input, staging, and fuel type before ordering — LP/propane variants may require the companion switch HK02LB008. Questions about fitment?
