OEM Carrier Dual Pressure Switch Assembly HK06NB020 for Model PG92SBS48060BBAA

This OEM dual pressure switch assembly is the factory-specified replacement for the Carrier PG92SBS48060BBAA 92% AFUE packaged gas furnace. The pressure switch monitors negative pressure created by the inducer motor to confirm proper venting before allowing ignition to proceed. When it fails, the control board will not advance past the inducer pre-purge stage, resulting in a no-heat lockout. Common symptoms include the inducer running continuously with no ignition attempt, a flashing fault code indicating a pressure switch failure, or a furnace that shuts off within seconds of startup. This listing covers both OEM part numbers: HK06NB020 (Dual Pressure Switch Assembly) and the companion HK02LB008 (Gas Pressure Switch) — both factory-authorized Carrier replacement components.

  • Specs: Dual pressure switch assembly | Factory W.C. (water column) rating matched to PG92SBS48060BBAA inducer | SPST normally-open configuration | Fits inducer outlet and gas valve pressure ports
  • OEM vs Generic: OEM switches are calibrated to the exact W.C. trip point specified by Carrier engineering. Generic aftermarket switches often carry ±15% tolerance on the trip point, which can cause nuisance lockouts or — worse — fail to detect a true venting failure, creating a safety hazard.
  • Install difficulty: 2/5 — Disconnect power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, and a digital manometer (recommended to verify W.C. after install). Note the orientation and routing of all rubber hose connections before removal. Always clear any fault codes after replacement.
  • Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse.

Compatibility: Designed for the Carrier PG92SBS48060BBAA packaged gas furnace. Replaces OEM part numbers HK06NB020 and HK02LB008. Verify your unit's data plate and existing pressure switch W.C. rating before ordering to ensure an exact match. Our HVAC parts specialists are available to confirm fitment — contact us before you order if you have any questions.

Is this pressure switch compatible with Bryant or Payne too?

Should I use OEM or aftermarket for my Carrier pressure switch?
