OEM Carrier High Pressure Switch 406/300 PSI — HK02ZA395 for Model PY2PNB024060NC

This OEM high pressure switch (part number HK02ZA395) is the factory-authorized refrigerant-side safety device for the Carrier PY2PNB024060NC packaged unit. It continuously monitors refrigerant circuit pressure on the high side and cuts power to the compressor when pressure exceeds a safe threshold, protecting the compressor from catastrophic failure. A failed or out-of-spec switch typically causes one of two symptoms: nuisance high-pressure lockouts on hot days (switch opens prematurely) or, if the switch fails open, a compressor that runs without safety protection. Replacing with the exact OEM switch restores factory-calibrated protection.

  • Specs: Opens at 395 PSI | Closes at 295 PSI | 406/300 rating | 6(6)A | 240 VAC | PMAX 41B | Sensata-manufactured | Carrier Factory Authorized Part
  • OEM vs Generic: This is a genuine Carrier OEM part — factory-set trip points guarantee your compressor cuts out at the correct pressure. Aftermarket switches with loose tolerances can allow over-pressure conditions that void compressor warranties.
  • Install difficulty: 2/5 — Requires recovering refrigerant per EPA 608 regulations before removing the switch. Tools needed: refrigerant recovery machine, manifold gauge set, adjustable wrench, leak detector. Always verify system pressure is at zero before disconnecting. Recommend licensed HVAC technician.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PY2PNB024060NC packaged unit. Also supersedes legacy part numbers 312926-217, 71267D1, HK02ZA380, HK02ZA396, 19240027, HK02ZA400, 312926-225, 312926-226, 312926-233, HK02ZA401, HK02ZA435, HK02ZA500, and HK02ZA501.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PY2PNB024060NC?
Yes. This is the factory-specified OEM pressure switch for the Carrier PY2PNB024060NC. 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 PY2PNB024060NC?
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?
