OEM Carrier Pressure Switch HK06WC061 for Model LC350HE400809

This OEM pressure switch (part number HK06WC061) is the factory-specified replacement for the Carrier LC350HE400809 furnace. The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or becomes stuck, the furnace will lock out before ignition — often displaying a pressure switch fault code — leaving you with no heat. Common symptoms include repeated short-cycling, a flashing fault code on the control board, or a furnace that runs the inducer motor but never advances to ignition.

  • Specs: OEM part number HK06WC061 | Factory-calibrated W.C. (water column) rating | Single-port pressure switch | 24V control circuit compatible | Direct drop-in replacement for Carrier LC350HE400809
  • OEM vs Generic: This is a genuine OEM Carrier pressure switch manufactured to exact factory W.C. specifications. Aftermarket pressure switches frequently carry incorrect trip points, causing nuisance lockouts or — more dangerously — allowing operation under improper draft conditions. OEM is the only safe choice for this safety-critical component.
  • Install difficulty: 2/5 — Disconnect power before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, and a manometer for post-install verification. Inspect the rubber hose connecting the switch to the inducer housing for cracks or blockages before replacing the switch, as a clogged hose is a frequent root cause of pressure switch faults.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier LC350HE400809 furnace. Always cross-reference the part number HK06WC061 against your unit's wiring diagram and data plate before ordering. If you're unsure about fitment, our HVAC parts specialists are available to verify compatibility before you purchase — ensuring you get the right part the first time.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier LC350HE400809?
Yes. This is the factory-specified OEM pressure switch for the Carrier LC350HE400809. 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 LC350HE400809?
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?
