OEM Carrier Draft Pressure Switch HK06WC061 — 0.18" WC for Model PY4GEAB36060AA

This is the OEM-specified draft inducer pressure switch for the Carrier PY4GEAB36060AA packaged unit. The pressure switch is a critical safety component that 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 safe flue-gas exhaust, triggering a system lockout — the most common symptom is the furnace or packaged unit attempting to start, then shutting down immediately with no heat delivered. A failed inducer, cracked hose, or blocked drain can also mimic a bad switch, so always verify inducer operation and hose integrity before condemning this part.

  • Specs: 0.18" W.C. (water column) rated | Normally open | Single-port | Replaces Honeywell IS20224-5236 | Cross-reference: HK06MB061 (OEM successor part)
  • OEM vs Generic: This OEM-matched switch is calibrated to the exact setpoint required by the Carrier PY4GEAB36060AA control board. Off-spec generic switches with incorrect W.C. ratings can cause nuisance lockouts or — more dangerously — allow the system to fire without confirmed draft, creating a carbon monoxide risk.
  • Install difficulty: 2/5 — Shut off power and gas before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, and a manometer (recommended to verify W.C. setpoint after install). Disconnect the rubber sensing hose and two wire terminals, then swap and reconnect. Always inspect the hose for cracks or blockages while the switch is out.
  • Warranty: 1-year OEM-equivalent warranty. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed for the Carrier PY4GEAB36060AA packaged unit. Also fits select Carrier, Bryant, and Payne models requiring a 0.18" W.C. normally-open draft pressure switch — verify your unit's data plate and existing switch rating before ordering. Note: OEM part number HK06WC061 has been superseded by HK06MB061; this listing covers both the original and successor specification. Questions about fitment? Our HVAC parts team confirms compatibility before you buy.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PY4GEAB36060AA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PY4GEAB36060AA. 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 PY4GEAB36060AA?
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?
