OEM Carrier Draft Inducer Pressure Switch 0.18" WC for Model PY3GNA024060NA

This OEM draft inducer pressure switch is the factory-specified replacement for the Carrier PY3GNA024060NA 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 open, the control board cannot verify that combustion gases are being safely exhausted — resulting in a hard lockout before the burners ever fire. Common symptoms include a furnace that attempts to start but shuts down immediately, error codes indicating a pressure switch fault, or an inducer motor that runs continuously with no ignition.

  • Specs: 0.18" Water Column (WC) | SPST normally open | OEM part HK06WC061 (superseded by HK06MB061) | Honeywell-manufactured switch IS20224-5236
  • OEM vs Generic: OEM switches are calibrated to exact factory set-point tolerances. Off-brand substitutes with loose WC tolerances can cause nuisance lockouts or, worse, allow ignition under unsafe venting conditions.
  • Install difficulty: 2/5 — Shut off power and gas before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, and a manometer to verify inducer static pressure if nuisance lockouts persist. Photograph all hose and wiring connections before removal.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Designed for Carrier model PY3GNA024060NA packaged gas/electric units. This part number has been superseded — current shipping equivalent is HK06MB061, which is a direct OEM drop-in replacement. Verify the 0.18" WC rating on your existing switch before ordering.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PY3GNA024060NA — HK06WC061?
Yes. This is the factory-specified OEM pressure switch for the Carrier PY3GNA024060NA — 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 PY3GNA024060NA — 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.
