OEM Carrier Pressure Switch Assembly with Bracket (HK06WC069) for Model PG8MAA060155ACJA

This is the factory OEM pressure switch assembly with bracket for the Carrier PG8MAA060155ACJA gas furnace. The pressure switch is a critical safety component that monitors negative pressure created by the draft inducer motor. If the inducer is running and producing adequate airflow, the switch closes — proving a safe venting path and allowing the ignition sequence to proceed. When this switch fails, the furnace locks out before ignition: the inducer runs, but the burners never light. You may see a diagnostic fault code indicating an open pressure switch, or the system simply repeats an ignition attempt cycle without ever firing.

• Specs: 0.27" W.C. Break | 0.42" W.C. Max Make | High Fire rated | Honeywell OEM (IS20205-4021) | Includes factory mounting bracket | Replaces HK06WC069 / HK06WC069A
• OEM vs Generic: This is the exact factory-specified Honeywell switch Carrier installs at the plant. OEM switches maintain precise W.C. ratings within tight tolerances — off-spec aftermarket switches can cause nuisance lockouts or, worse, fail to detect a true venting fault.
• Install difficulty: 2/5 — Shut off gas and power before beginning. Disconnect the pressure hose and two wiring terminals, unbolt the bracket, and reverse the steps for the new assembly. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers. Note wire positions before disconnecting. Typical repair time: 20–30 minutes.
• Warranty: 1-year OEM manufacturer warranty against defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier PG8MAA060155ACJA packaged gas furnace. Verify your existing switch's W.C. rating on the label before ordering. Not sure it fits? Our HVAC parts team confirms fitment before you buy — just ask.
