OEM Carrier Pressure Switch Assembly with Bracket (HK06WC069) for Model PG8MAA066110ABJA

This is the factory OEM pressure switch assembly with mounting bracket for the Carrier PG8MAA066110ABJA gas furnace. The pressure switch is a critical safety and sequencing component that monitors negative pressure created by the inducer motor. Once the inducer establishes proper draft, the switch closes its normally-open contacts, signaling the control board to proceed with ignition. If this switch fails — whether stuck open, stuck closed, or due to a ruptured diaphragm — the furnace will lock out before ignition, displaying a fault code and leaving your home without heat.

  • OEM Part Number: HK06WC069 | Pressure Switch Assembly with Bracket | Factory-specified replacement for Carrier PG8MAA066110ABJA furnaces | Includes pre-installed mounting bracket for direct drop-in installation
  • OEM vs Generic: This is a genuine Carrier OEM part, not an aftermarket substitute. OEM pressure switches are factory-calibrated to the exact water column (W.C.) rating your furnace requires. Generic switches often carry wider tolerances that can cause nuisance lockouts or, worse, unsafe operation.
  • Install Difficulty: 2/5 — Straightforward replacement accessible in the furnace cabinet. Tools needed: 1/4" nut driver, flat-head screwdriver, and needle-nose pliers. Disconnect power before servicing. Photograph the hose connection and wiring before removal. Always inspect the rubber pressure hose for cracks or blockage before condemning the switch.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — get your furnace back online fast.

Compatibility: Engineered specifically for the Carrier PG8MAA066110ABJA gas furnace. The included bracket ensures a bolt-in fit with no modification required. Verify your existing switch's W.C. rating on the data tag before ordering if your unit has been previously serviced. Not sure it fits? Contact our HVAC parts team — we verify fitment before you buy.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8MAA066110ABJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8MAA066110ABJA. 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 PG8MAA066110ABJA?
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?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
