OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8JAA048110ADJA

This is the genuine OEM Carrier Pressure Switch Assembly with Bracket (part number HK06WC069), factory-specified for the Carrier PG8JAA048110ADJA gas furnace. The pressure switch is a critical safety device that monitors negative pressure created by the inducer motor. Before each ignition attempt, the control board reads this switch to confirm the inducer is running and that flue gases are being properly vented. If the switch fails — or if the inducer motor, hose, or port is compromised — the switch won't close, and the furnace will lock out before ever reaching ignition, leaving you with no heat.

  • Specs: Single-stage draft pressure switch | .27" W.C. break / .42" W.C. max make | Includes factory mounting bracket | Honeywell-manufactured (IS20205-4021 equivalent) | OEM part number HK06WC069
  • OEM vs Generic: OEM switches are calibrated to exact W.C. (water column) thresholds for your specific furnace. Generic alternatives frequently deviate from factory setpoints, causing nuisance lockouts or — more dangerously — failing to detect a true venting fault. Always verify the W.C. rating before substituting.
  • Install Difficulty: 2/5 — Tools needed: 1/4" nut driver, needle-nose pliers, and a small flathead screwdriver to release the hose barb clip. Disconnect power before servicing. Photograph all hose and wire connections before removal. Before condemning the switch, check the inducer port and rubber hose for cracks, blockage, or moisture — these cause identical symptoms.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered and factory-matched for the Carrier PG8JAA048110ADJA packaged gas furnace. Also fits select Bryant and Payne models sharing the same pressure switch specification — confirm your model and the W.C. rating on your existing switch before ordering. Not sure it fits? Our HVAC parts specialists verify fitment at no charge — contact us before you buy.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8JAA048110ADJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8JAA048110ADJA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the pressure switch on my Carrier PG8JAA048110ADJA?
Difficulty: Medium (20–30 min)
Step 1: Turn off power. Step 2: Locate pressure switch near draft inducer. Step 3: Note tubing orientation. Step 4: Disconnect tubing and wires. Step 5: Remove screw, install new switch. Step 6: Reconnect tubing and wires, restore power.
My furnace shows a pressure switch error. What do I replace?
Furnace LED showing pressure switch error = switch not detecting draft inducer airflow. Try first: clear the rubber tubing to the switch (often clogged with condensation). If problem persists, replace the pressure switch.
Is this pressure switch compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier pressure switch?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
