OEM Carrier Pressure Switch w/ Bracket -0.33 WC for Model PG8DAA024070ACJA

This is the genuine OEM replacement pressure switch (part #HK06WC090) factory-specified for the Carrier PG8DAA024070ACJA packaged gas furnace. The pressure switch is a safety device that monitors the negative pressure (draft) created by the inducer motor before allowing the ignition sequence to proceed. When the inducer spins up and generates the correct draft, the switch closes its contacts and signals the control board to continue with ignition. A failed pressure switch will cause the furnace to lock out before it ever reaches the ignition stage — often displaying a fault code for an open or stuck pressure switch.

  • Specs: -0.33 in. W.C. (water column) rating | Single-port diaphragm-type switch | Includes mounting bracket | OEM part #HK06WC090 | Replaces HK06WC088, HK06WC086, HK06WC076, HK06WC072, HK06WC073, HK06WC074, HK660001
  • OEM vs Generic: This is a genuine Carrier OEM switch, factory-calibrated to the exact -0.33 W.C. trip point required by your furnace's IFC board. Off-brand substitutes may trip at incorrect pressure thresholds, causing nuisance lockouts or — more dangerously — allowing operation under inadequate draft conditions.
  • Install difficulty: 2/5 — Turn off power and gas before beginning. Disconnect the rubber hose from the inducer outlet port and the two electrical spade connectors. Remove the bracket screw, swap the switch, and reconnect. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers. Always check the hose for cracks or blockage before condemning the switch.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM fit for Carrier PG8DAA024070ACJA packaged gas furnaces. Also compatible with several other PG8DAA and PG8UAA series models — verify your unit's data plate and existing switch W.C. rating before ordering. Our parts specialists can confirm fitment at no charge. Order by 3 PM local time for same-day shipping.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8DAA024070ACJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8DAA024070ACJA. 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 PG8DAA024070ACJA?
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?
