OEM Carrier Draft Inducer Pressure Switch 0.18" WC for Model PY3GNA060130NA

This OEM draft inducer pressure switch is the factory-specified replacement for the Carrier PY3GNA060130NA gas furnace. The pressure switch monitors negative pressure created by the inducer blower motor at startup, confirming that combustion gases are being safely vented before allowing the ignition sequence to proceed. When this switch fails or sticks open, the furnace control board never receives proof of draft — resulting in a hard lockout before the burners ever fire. Common symptoms include a furnace that runs the inducer motor but never advances to ignition, flashing fault codes indicating an open pressure switch, or a system that locks out after 3 attempts.

  • Specs: 0.18" W.C. (water column) set point | SPST (Single Pole, Single Throw) | Replaces OEM part HK06WC061 (superseded by HK06MB061) | Factory-matched Honeywell sensing element
  • OEM vs Generic: OEM pressure switches are calibrated to exact W.C. tolerances at the factory. Generic aftermarket switches frequently drift from their rated set point, causing nuisance lockouts or — more dangerously — failing to detect a true draft failure, which is a combustion safety hazard.
  • Install difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, and a short length of replacement hose (5/16" I.D. silicone tubing recommended). Inspect the rubber hose connecting the switch to the inducer housing for cracks or blockages before installing — a blocked hose is a frequent root cause of switch failure.
  • Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed for Carrier model PY3GNA060130NA gas furnace. This part supersedes original OEM part number HK06WC061; the current shipping part is HK06MB061 — both are fully interchangeable. Also cross-references Honeywell part numbers IS20224-5236 and 1938D2/B. Confirm the 0.18" W.C. rating on your existing switch before ordering. Questions about fitment? Our HVAC parts specialists verify compatibility before you buy — ships today.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PY3GNA060130NA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PY3GNA060130NA. 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 PY3GNA060130NA?
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?
