OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8MAA048110ADJA

This is the genuine OEM Carrier Pressure Switch Assembly with Bracket (part number HK06WC069), factory-specified for the Carrier PG8MAA048110ADJA gas furnace. The pressure switch is a critical safety device that monitors negative pressure (draft) created by the inducer blower motor. Before every ignition cycle, the control board checks this switch to confirm the inducer is operating and the flue is clear. When the switch fails — or the hose, port, or inducer driving it fails — the board locks out the furnace before the gas valve ever opens, leaving you with a no-heat call and often a fault code pointing directly to draft pressure.

• Specs: Single-stage draft pressure switch | Includes factory mounting bracket | .27" W.C. break / .42" W.C. max make | Honeywell-manufactured internals (IS20205-4021) | OEM-matched setpoint — no field calibration required
• OEM vs Generic: This factory OEM part is pre-set to the exact W.C. rating engineered for the PG8MAA048110ADJA. Aftermarket substitutes are often rated at wider tolerances, risking nuisance lockouts or, worse, failing to detect a true flue blockage.
• Install difficulty: 2/5 — Power down and disconnect gas before starting. Tools needed: 1/4" nut driver, needle-nose pliers, and a short length of replacement hose if the existing tubing is cracked. Always inspect the rubber hose and inducer port for blockage before condemning the switch itself — a clogged port is the #1 misdiagnosis.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
