OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8MAA048135ACJA

This is the genuine OEM Carrier Pressure Switch Assembly with Bracket (part #HK06WC069), the factory-specified replacement for the Carrier PG8MAA048135ACJA packaged gas furnace. The pressure switch is a critical safety component that monitors negative pressure generated by the inducer draft motor. Once the inducer reaches proper airflow, the switch closes and signals the control board to continue the ignition sequence. When it fails, the furnace will lock out before ignition — leaving you with no heat and often a flashing fault code indicating a pressure switch error.

• Specs: Single-stage pressure switch | Rated 0.27" W.C. break / 0.42" W.C. max make | Includes factory bracket assembly | Direct OEM replacement — no modification required
• OEM vs Generic: This is a genuine Carrier OEM part, manufactured to exact factory specifications. Aftermarket pressure switches often use wider tolerance membranes that can trip falsely or fail to prove draft reliably, leading to repeated no-heat lockouts and unnecessary service calls.
• Install difficulty: 2/5 — A straightforward swap accessible in the control compartment. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a manometer if verifying switch set-point. Always power down the furnace at the disconnect and thermostat before beginning work. Check the rubber hose connecting the inducer to the switch for cracks or blockages before installing.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
