OEM Carrier Pressure Switch w/ Bracket -0.33 WC for Model PG8DAA048095AAJA

This is the genuine OEM replacement pressure switch with bracket (part number HK06WC090) factory-specified for the Carrier PG8DAA048095AAJA gas furnace. The pressure switch is a safety device that monitors negative pressure created by the inducer motor to confirm proper venting before allowing ignition to proceed. When it fails or sticks open, the control board cannot verify that combustion gases are being safely exhausted — resulting in a no-heat lockout, a flashing fault code, or a furnace that attempts to start but shuts down before the burners ever light.

  • Specs: -0.33 W.C. (inches water column) setpoint | Includes factory mounting bracket | SPST normally open | Rated for single-stage induced-draft gas furnace application | Replaces superseded part numbers HK06WC088, HK06WC086, HK660001, HK06WC076, HK06WC072, HK06WC073, HK06WC074, 326750-751, 310315-751, 310315-752
  • OEM vs Generic: This OEM unit is factory-calibrated to the exact -0.33 W.C. trip point required by your Carrier furnace. Generic pressure switches frequently carry wider tolerances that can cause nuisance lockouts in cold weather or — more dangerously — fail to open when venting is truly compromised.
  • Install difficulty: 2/5 — Power down the furnace and allow the inducer to cool before starting. Tools needed: 1/4" nut driver, flathead screwdriver, and a short length of 3/16" ID rubber tubing if the existing hose shows cracking. Always inspect the hose barb and rubber tubing for blockages before condemning the switch — a clogged hose is the #1 cause of false pressure switch failure.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse.

Compatibility: Designed and factory-matched for the Carrier PG8DAA048095AAJA packaged gas furnace. Also fits other Carrier, Bryant, and Payne induced-draft furnace models requiring the -0.33 W.C. pressure switch. Verify your existing part number or data plate W.C. rating before ordering. Our parts specialists are available to confirm fitment — just reach out before you buy. Order today and your part ships the same business day.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8DAA048095AAJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8DAA048095AAJA. 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 PG8DAA048095AAJA?
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?
