OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8JAA048070ACJA

This is the genuine OEM Carrier pressure switch assembly with mounting bracket, part number HK06WC069, factory-specified for the Carrier PG8JAA048070ACJA gas furnace. The pressure switch is a safety device that monitors negative pressure created by the inducer (draft) motor to confirm proper venting before allowing the ignition sequence to proceed. When the inducer fails to develop adequate draft — or when the switch itself fails — the control board receives no proof signal and locks out the furnace before any gas is released. Common symptoms of a failed pressure switch include the furnace cycling the inducer but never advancing to ignition, a blinking fault code for "pressure switch open," or a furnace that starts briefly and immediately shuts down.

  • Specs: Opening set point: -0.27" W.C. | Max make pressure: -0.42" W.C. | Includes factory mounting bracket | Single-stage, normally open configuration | Honeywell/Carrier OEM sensing element
  • OEM vs Generic: This factory OEM assembly uses precision-calibrated sensing diaphragms held to exact W.C. tolerances. Aftermarket substitutes frequently drift outside spec, causing nuisance lockouts or — worse — allowing ignition under unsafe draft conditions. OEM is the only choice for a safety-critical component.
  • Install difficulty: 2/5 — Power down and confirm inducer is off before disconnecting the pressure hose. Tools needed: 1/4" nut driver, flathead screwdriver, manometer (recommended for post-install verification). Always inspect and clear the rubber sense tube for cracks or blockages before installing the new switch.
  • Warranty: 1-year OEM factory warranty on parts. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Direct OEM replacement for Carrier PG8JAA048070ACJA gas furnace. Also fits select Bryant and Payne furnace models sharing the same inducer assembly — verify part number on your existing switch label before ordering. Our team is available to confirm fitment. Order today and receive fast, same-day shipping!

How do I replace the pressure switch on my Carrier OEM Carrier Pressure Switch Assembly w/Bracket HK06WC069 — PG8JAA04807?
Difficulty: Medium (20–30 min)

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.
