OEM Carrier High Pressure Switch HK02ZA395 406/300 PSI for Model PY1PPB060090AAAA

This is the genuine OEM high pressure safety switch for the Carrier PY1PPB060090AAAA packaged unit. The high pressure switch monitors refrigerant pressure on the high side of the refrigerant circuit and cuts power to the compressor if pressure exceeds a safe threshold, protecting against compressor damage, refrigerant line rupture, and system failure. When this switch fails or trips permanently, you'll typically experience a system lockout, a no-cooling fault code, or repeated nuisance trips even when the refrigerant charge is correct. A failed or out-of-spec switch must be replaced — not bypassed.

  • Specs: Opens at 406 PSI | Closes at 295 PSI | 6(6)A | 240 VAC | PMAX 41B | Manufactured by Sensata (PS80-03-0018) — factory-matched to Carrier tolerances
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part. OEM switches are calibrated to exact cut-out/cut-in pressures. Aftermarket alternatives often carry wider pressure tolerances, risking either premature trips or — more dangerously — delayed shutoff that allows compressor damage.
  • Install Difficulty: 3/5 — Refrigerant-side work. You must recover refrigerant before replacing a high pressure switch on a pressurized circuit. Tools needed: manifold gauge set, refrigerant recovery unit, adjustable wrench, wire stripper. Always tag and lock out power before beginning. A licensed HVAC technician is recommended for this repair.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier PY1PPB060090AAAA packaged unit. Also supersedes legacy part numbers 312926-217, 71267D1, HK02ZA380, HK02ZA396, HK02ZA400, HK02ZA401, HK02ZA435, HK02ZA500, HK02ZA501, 312926-225, 312926-226, and 312926-233.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PY1PPB060090AAAA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PY1PPB060090AAAA. 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 PY1PPB060090AAAA?
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?
