OEM Carrier Draft Proving Pressure Switch 0.18" WC for Model PY3GNA036060NA

This OEM draft pressure proving switch is the factory-specified replacement for the Carrier PY3GNA036060NA packaged unit. The pressure switch monitors negative pressure created by the inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or sticks, the control board cannot verify safe draft conditions — resulting in a furnace lockout before ignition, a blinking fault code, or a system that attempts to start and immediately shuts down. Part number HK06WC061 has been updated by the manufacturer to successor part HK06MB061, which is a direct OEM drop-in replacement with identical specifications.

  • Specs: 0.18" W.C. (water column) set point | Normally open | Single-port diaphragm design | Factory-calibrated for precise draft proving | Compatible with Carrier, Bryant, and Payne platforms
  • OEM vs Generic: OEM pressure switches are calibrated to exact W.C. tolerances at the factory. Aftermarket units can drift out of spec, causing nuisance lockouts or — worse — failing to detect a blocked flue, which is a safety-critical failure.
  • Install difficulty: 2/5 — Shut off power and gas before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, and needle-nose pliers. Disconnect the single rubber hose port and two spade wire terminals, then reverse to install. Always inspect the hose and port for cracks or blockages while the switch is out.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PY3GNA036060NA packaged unit. Also fits a wide range of Carrier, Bryant, and Payne furnaces, packaged units, heat pumps, and air handlers requiring a 0.18" W.C. normally-open draft pressure switch. Verify the W.C. rating on your existing switch or equipment data plate before ordering. Our HVAC parts specialists are available to confirm fitment — reach out before you order if you have any questions. In stock and ships today.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PY3GNA036060NA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PY3GNA036060NA. 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 PY3GNA036060NA?
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?
