OEM Carrier High Pressure Switch HK02ZA395 — 406/300 PSI for Model PH1PNA030000ABBA

This is the genuine OEM factory-replacement high pressure switch for the Carrier PH1PNA030000ABBA packaged heat pump system. The high pressure switch is a critical refrigerant-side safety device that continuously monitors system discharge pressure. When refrigerant pressure rises above the cutout threshold — due to a dirty condenser coil, failed condenser fan motor, restricted airflow, or refrigerant overcharge — the switch opens the control circuit, shutting down the compressor to prevent catastrophic failure. Symptoms of a failed or tripped switch include the system locking out on high pressure fault, the compressor shutting off within minutes of startup, or the unit not cooling or heating at all while the fan continues to run.

  • Specs: Opens at 406 PSI | Closes (resets) at 300 PSI | Rated 6(6)A at 240 VAC | 1/8" NPT male thread connection | Sensata PS80-03-0018 platform | PMAX 41B | CE / EN12263 / ENEC05 certified
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part manufactured by Sensata to exact OEM cutout tolerances. Generic switches often carry ±5–10% PSI variance, which can allow unsafe pressure spikes or cause nuisance trips — both costly outcomes on a packaged unit compressor.
  • Install difficulty: 3/5 — Requires EPA 608 certification to work on the refrigerant circuit. Tools needed: manifold gauge set, 1/8" NPT fitting, refrigerant recovery equipment, and a multimeter to confirm switch continuity. Always recover refrigerant before removing the switch and recheck system pressures after reinstallation.
  • Warranty & Shipping: 1-year OEM factory warranty. Ships same business day from our warehouse. Replaces superseded part numbers: 312926-217, 71267D1, HK02ZA380, HK02ZA396, HK02ZA400, HK02ZA401, HK02ZA435, HK02ZA500, HK02ZA501, P332-1103.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PH1PNA030000ABBA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PH1PNA030000ABBA. 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 PH1PNA030000ABBA?
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?
