OEM Carrier High-Fire Pressure Switch HK06WC091 for Model PG8JVB066135AAJA

This OEM Carrier pressure switch (part number HK06WC091) is the factory-specified draft-proving switch for the Carrier PG8JVB066135AAJA gas furnace. The pressure switch monitors the vacuum created by the induced-draft blower to confirm safe venting conditions before the control board allows ignition to proceed. When this switch fails, it breaks the proving circuit — causing the furnace to lock out before ignition, often with a flashing fault code indicating an open pressure switch. Common symptoms include a furnace that starts the inducer motor but never advances to ignition, or one that attempts ignition and immediately trips into hard lockout.

  • Part Specs: SPST (Single-Pole, Single-Throw) | High-Fire rated | Factory Authorized Part manufactured by Honeywell for Carrier | Replaces superseded part; current OEM cross is HK06MC110
  • OEM vs Generic: OEM pressure switches are calibrated to exact water-column (W.C.) trip points specified for your furnace's inducer and heat exchanger. Generic alternatives may use wider tolerances, risking nuisance trips or — more critically — failure to prove a venting fault, which creates a carbon monoxide hazard.
  • Install Difficulty: 2/5 — Disconnect power and gas before starting. Tools needed: 1/4" nut driver, needle-nose pliers, and a short length of replacement hose if the original is cracked. Note the hose port orientation and wire terminal positions before disconnecting. Swap hose and spade terminals, restore power, and verify ignition sequence.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8JVB066135AAJA gas furnace. Also fits many Carrier, Bryant, and Payne gas furnace applications sharing this high-fire pressure switch specification — verify your data plate and existing part number before ordering. Note: HK06WC091 has been superseded; this listing ships the current OEM replacement. Questions about fitment? Our HVAC parts team confirms compatibility before your order ships.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8JVB066135AAJA — HK06WC091?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8JVB066135AAJA — HK06WC091. 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 PG8JVB066135AAJA — HK06WC091?
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?
