OEM Carrier Draft Pressure Switch 0.18" WC SPST for Model PY3GNA060130AA

This OEM draft inducer pressure switch (part number HK06WC061, superseded by HK06MB061) is the factory-specified replacement for the Carrier PY3GNA060130AA packaged gas unit. The pressure switch monitors negative pressure created by the inducer draft motor to confirm safe venting before allowing the ignition sequence to proceed. When it fails or sticks open, the control board cannot verify that combustion gases are being properly exhausted — causing the furnace to lock out before the burners ever fire. Common symptoms include a blinking fault code indicating a pressure switch error, the inducer running but the burners never lighting, or the system cycling on and off without producing heat.

  • Specs: 0.18" Water Column (WC) set point | SPST (Single-Pole, Single-Throw) | Normally Open | Replaces OEM part HK06WC061 — current ship part: HK06MB061 | Also replaces Honeywell IS20224-5236
  • OEM vs Generic: This is a genuine Carrier OEM pressure switch calibrated to the exact 0.18" WC set point required by the PY3GNA060130AA. Generic alternatives are often rated at approximate tolerances and can result in nuisance lockouts or, worse, unsafe ignition attempts with inadequate draft.
  • Install difficulty: 2/5 — Shut off power and gas before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, and a digital manometer (recommended to verify draft pressure after install). Photograph wiring and tubing routing before disconnecting. Swap the pressure hose and two wire terminals, then confirm no fault codes on startup.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3GNA060130AA packaged gas/electric unit. Note that HK06WC061 has been superseded by HK06MB061 — both part numbers are fulfilled with the current OEM replacement. Always verify your unit's data plate and existing switch markings before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork needed.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PY3GNA060130AA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PY3GNA060130AA. 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 PY3GNA060130AA?
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?
