OEM Carrier High Pressure Switch HK02ZA395 / HK02ZB044 for Model PH2PNB060000AA

This genuine OEM Carrier high pressure switch (part number HK02ZA395, with companion switch HK02ZB044) is the factory-specified refrigerant circuit protection device for the Carrier PH2PNB060000AA packaged heat pump unit. The high pressure switch monitors refrigerant discharge pressure on the high side of the refrigerant circuit. When system pressure exceeds the factory-set threshold — typically caused by a dirty condenser coil, failed condenser fan motor, overcharge, or a blocked refrigerant circuit — the switch opens to protect the compressor from catastrophic damage. Symptoms of a failed switch include nuisance high-pressure lockouts, a system that trips off on warm days but not cool ones, or a compressor that won't engage after a manual reset.

  • Specs: Opens at 395 PSI | Closes at 295 PSI | Rated 6(6)A @ 240 VAC | PMAX 41B | 1/8" NPT thread | Sensata PS80-03-0018 platform
  • OEM vs Generic: This is a genuine Carrier OEM part manufactured to exact factory pressure setpoints. Aftermarket switches frequently deviate ±10–15% from rated trip pressure, risking either nuisance lockouts or — worse — inadequate compressor protection under true over-pressure conditions.
  • Install Difficulty: 3/5 — Refrigerant circuit must be recovered before replacing the high-side pressure switch. Tools needed: manifold gauge set, refrigerant recovery machine, 1/8" NPT wrench, leak detector. Recommended for certified HVAC-R technicians (EPA 608 required for refrigerant handling).
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Direct OEM replacement for the Carrier PH2PNB060000AA packaged heat pump. Also replaces legacy part numbers 312926-217, 71267D1, HK02ZA380, HK02ZA396, HK02ZA400, HK02ZA401, HK02ZA435, HK02ZA500, and HK02ZA501. Always verify refrigerant type and system operating pressures against your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you purchase.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PH2PNB060000AA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PH2PNB060000AA. 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 PH2PNB060000AA?
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?
