OEM Carrier Pressure Switch HK06WC061 for Model LC350LC400470

This is the factory OEM replacement pressure switch (part number HK06WC061) for the Carrier LC350LC400470 furnace. The pressure switch is a safety device that monitors negative pressure created by the inducer draft motor. Before allowing ignition to proceed, it confirms the inducer is operating correctly and that the flue path is clear. When this switch fails — or becomes stuck open — the control board cannot verify proper draft, and the furnace will lock out before ever reaching the ignition stage. Common symptoms include a furnace that runs the inducer but never advances to heating, repeated error codes for pressure switch faults, or a furnace that attempts ignition briefly before shutting down entirely.

  • Specs: Factory-calibrated W.C. (water column) rating matched to the LC350LC400470 | Single-port or dual-port design per OEM specification | 24V control circuit compatible | Exact hose barb diameter for direct drop-in fit
  • OEM vs Generic: OEM switches like this HK06WC061 are calibrated to Carrier's precise trip-point tolerances. Aftermarket pressure switches frequently carry wider tolerances that can cause nuisance lockouts in cold weather or — more dangerously — fail to trip when a real venting problem exists.
  • Install difficulty: 2/5 — Shut off power and gas before servicing. Tools needed: flathead screwdriver, needle-nose pliers, multimeter (to confirm open/closed continuity). Inspect the rubber hose connecting the switch to the inducer for cracks or moisture before reinstalling — a bad hose causes the same symptom as a bad switch.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier LC350LC400470 furnace. Always confirm the OEM part number HK06WC061 against your unit's data plate or existing switch label before ordering. Our fitment team is available to verify compatibility prior to purchase. Order today and enjoy same-day shipping on all in-stock OEM Carrier parts.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier LC350LC400470 — HK06WC061?
Yes. This is the factory-specified OEM pressure switch for the Carrier LC350LC400470 — HK06WC061. 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 LC350LC400470 — HK06WC061?
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?
