OEM Carrier Dual Pressure Switch Assembly HK06NB020 for Model PG96VAT60080CBAA

This OEM dual pressure switch assembly is the factory-specified replacement for the Carrier PG96VAT60080CBAA 96% AFUE gas furnace. The pressure switch is a critical safety component that monitors the negative pressure (vacuum) created by the inducer blower motor. When the inducer reaches proper operating speed and draft conditions are verified, the switch closes to allow the ignition sequence to proceed. A failed pressure switch will prevent the furnace from advancing past the inducer stage, resulting in a no-heat condition and a diagnostic fault code. Common failure symptoms include the inducer running continuously with no ignition attempt, repeated soft lockouts, or an error code indicating pressure switch failure.

• Specs: Dual pressure switch assembly | Two switch configuration | 2 wire terminals per switch | One hose port per switch | Factory-calibrated W.C. (water column) setpoints matched to PG96VAT60080CBAA inducer specifications
• OEM vs Generic: OEM switches are calibrated to exact W.C. setpoints from the factory. Off-brand substitutes can carry wide tolerances, leading to nuisance lockouts or — more critically — failure to detect a genuine venting fault, creating a safety risk.
• Install difficulty: 3/5 — Shut off gas and power before beginning. Tools needed: 1/4" nut driver, flat-head screwdriver, needle-nose pliers, and a manometer to verify switch operation post-install. Photograph all hose and wire connections before removal. Inspect rubber hose ports for cracks while the assembly is out.
• Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered for the Carrier PG96VAT60080CBAA 96% AFUE two-stage gas furnace. OEM part number HK06NB020; superseded by HK06MB020 — both are factory-approved for this application. Always confirm the W.C. rating on your existing switch before ordering. Our HVAC parts specialists are available to verify fitment prior to purchase — no guesswork, no return hassle.
