OEM Carrier Draft Pressure Switch 0.18" WC for Model PY4GNAB60130NA

This OEM Carrier draft pressure proving switch (part number HK06WC061, superseded by HK06MB061) is the factory-specified replacement for the Carrier PY4GNAB60130NA packaged unit. The pressure switch monitors negative pressure created by the inducer motor to confirm proper venting before allowing ignition to proceed. When it fails or sticks, the control board never receives the "all clear" signal — resulting in a no-heat lockout before a single ignition attempt is made. Symptoms include a blinking error code for pressure switch fault, an inducer that runs but ignition that never follows, or intermittent heating that stops during cold weather when flue pressure margins are tightest.

  • Specs: 0.18" W.C. (water column) setpoint | Single-port draft pressure switch | Honeywell OEM-equivalent (IS20224-5236) | Compatible with 24V control circuit | Current Carrier part: HK06MB061
  • OEM vs Generic: OEM switches are factory-calibrated to exact W.C. tolerances. Off-spec generic switches can trip too early or too late — masking real venting problems or causing nuisance lockouts that damage heat exchangers over time.
  • Install difficulty: 2/5 — Power off the unit at the disconnect before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Photograph existing tubing routing before disconnecting. Inspect inducer hose for cracks or blockages while the switch is out.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY4GNAB60130NA packaged gas/electric unit. Also fits select Bryant and Payne models sharing this pressure switch specification. Always verify the 0.18" W.C. rating on your existing switch before ordering. Have a question about fitment?

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PY4GNAB60130NA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PY4GNAB60130NA. 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 PY4GNAB60130NA?
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?
