OEM Carrier Pressure Switch with Bracket -0.33" WC for Model PG8DAA048095ABJA (Part# HK06WC090)

This OEM Carrier pressure switch with bracket (HK06WC090) is the factory-specified replacement for the Carrier PG8DAA048095ABJA packaged gas furnace. The pressure switch is a critical safety component that monitors the negative pressure (draft) created by the inducer motor. Once the inducer reaches proper speed and venting is confirmed, the pressure switch closes to allow the ignition sequence to proceed. When it fails or sticks open, the control board interprets this as a venting fault and shuts down the furnace — typically resulting in a no-heat call with a flashing fault code before the burners ever fire.

  • Specs: -0.33" W.C. (inches of water column) set point | Includes factory mounting bracket | SPST normally-open configuration | Direct OEM replacement — no field calibration required
  • OEM vs Generic: This is a genuine Carrier OEM part, manufactured to exact factory W.C. tolerances. Off-brand pressure switches frequently carry ±10–15% W.C. variance, which can cause nuisance lockouts or — worse — fail to detect real venting failures, creating a safety hazard.
  • Install difficulty: 2/5 — Disconnect power before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, and a short length of replacement hose (inspect existing hose for cracks while you're in there). Photograph the hose routing and wiring spade connectors before removal. Replaces legacy part numbers HK06WC088, HK06WC086, HK06WC076, HK06WC072, HK06WC073, HK06WC074, HK660001.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before 3 PM ship same business day from our warehouse.

Compatibility: Engineered for the Carrier PG8DAA048095ABJA packaged gas furnace. Always verify the W.C. rating stamped on your existing pressure switch and cross-reference the part number on your unit's data plate or wiring diagram before ordering. Our HVAC parts specialists are available to confirm fitment — reach out before you buy if you have any questions.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8DAA048095ABJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8DAA048095ABJA. 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 PG8DAA048095ABJA?
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?
