OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8MAA036070ACJA

This is the genuine OEM Carrier Pressure Switch Assembly with Bracket (part number HK06WC069), factory-specified for the Carrier PG8MAA036070ACJA gas furnace. The pressure switch is a critical safety and sequencing component that monitors negative pressure (vacuum) produced by the inducer/draft motor. When the inducer motor spins up and creates sufficient draft, this switch closes to signal the control board that it is safe to proceed with ignition. If the switch fails — or if it cannot sense adequate pressure — the furnace will lock out on a fault code before any ignition attempt, leaving you with no heat.

• Part Specs: OEM Carrier part number HK06WC069 | Pressure Switch Assembly with integrated mounting bracket | Single-stage pressure sensing | Rated for natural gas and LP applications | Factory-calibrated W.C. (water column) set point — no adjustment required
• OEM vs Generic: OEM pressure switches are calibrated to the exact W.C. threshold specified by Carrier engineering for the PG8MAA036070ACJA. Generic substitutes often carry ±10–15% tolerance on set points, which can cause nuisance lockouts or — more dangerously — allow operation without verified inducer draft.
• Install Difficulty: 2/5 — Straightforward swap accessible from the furnace cabinet. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers for hose clamp, multimeter to verify continuity before and after. Always power down the furnace at the disconnect and thermostat before servicing. Note the hose port orientation and bracket mounting position before removal.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock at NationalHVACParts.com — ships same business day when ordered before 3 PM local time.
