OEM Carrier Draft Inducer Pressure Switch 0.18" WC for Model PY3GNAA60130NA — HK06WC061

This is the factory-specified OEM pressure switch for the Carrier PY3GNAA60130NA packaged gas unit. The draft inducer pressure switch monitors negative air pressure created by the inducer motor to confirm safe venting conditions before ignition is permitted. When this switch fails or sticks open, the furnace will lock out before the ignition sequence begins — resulting in a no-heat call with a pressure switch fault code displayed on the control board. Common failure symptoms include the inducer running but the system never advancing to ignition, or intermittent heating loss on cold days when pressure differentials fluctuate.

  • Specs: 0.18" Water Column (WC) setpoint | SPST normally-open configuration | Replaces OEM part HK06WC061 (superseded by HK06MB061) | Also cross-references Honeywell IS20224-5236
  • OEM vs Generic: This genuine Carrier OEM switch is factory-calibrated to the exact 0.18" WC trip point required by the PY3GNAA60130NA. Generic alternatives often carry ±10–15% pressure tolerances that can cause nuisance lockouts or, worse, allow ignition under unsafe venting conditions.
  • Install Difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, and a manometer or magnahelic gauge to verify inducer draft post-installation. Always inspect the rubber pressure hose and hose barb fitting for cracks before reconnecting.
  • Warranty: 1-year OEM manufacturer warranty. In-stock orders ship same business day from our warehouse when ordered before cutoff.

Compatibility & Important Note: Fits Carrier model PY3GNAA60130NA packaged gas/electric units. OEM part HK06WC061 has been superseded by HK06MB061 — both part numbers are fulfilled with the current production replacement. Verify the 0.18" WC rating on your unit's wiring diagram or data plate before ordering. Our HVAC specialists are available to confirm fitment prior to purchase — contact us before you order if you have any doubt.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PY3GNAA60130NA — HK06WC061?
Yes. This is the factory-specified OEM pressure switch for the Carrier PY3GNAA60130NA — 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 PY3GNAA60130NA — 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?
