OEM Carrier High Pressure Switch HK02ZA395 — 406/300 PSI for Model PY2PEB060090NB

This is the genuine OEM high pressure switch (part number HK02ZA395) factory-specified for the Carrier PY2PEB060090NB packaged heat pump unit. The high pressure switch is a critical refrigerant-circuit safety device: it continuously monitors refrigerant discharge pressure and cuts power to the compressor when pressure exceeds safe limits, protecting your system from catastrophic compressor failure. When this switch fails — either stuck open or with a weakened diaphragm — you'll experience symptoms including nuisance high-pressure lockouts, compressor shutdowns on warm days, or a system that trips a fault code and refuses to restart without a manual reset.

  • Specs: Opens at 395 PSI (406# rated) | Closes at 295 PSI (300# rated) | 1/8" NPT thread fitting | 240 VAC rated | Sensata PS80-03-0018 platform | Replaces: 312926-217, 71267D1, HK02ZA380, HK02ZA396, HK02ZA400, HK02ZA401, HK02ZA435, HK02ZA500, HK02ZA501
  • OEM vs Generic: This is a genuine Carrier OEM part manufactured to exact factory pressure-trip tolerances. Aftermarket switches often have wider setpoint tolerances (±10–15 PSI), which can result in insufficient compressor protection or false lockouts — risking expensive compressor damage.
  • Install difficulty: 3/5 — Refrigerant system work requires an EPA 608-certified technician. The refrigerant circuit must be recovered before replacing this switch. Tools needed: refrigerant recovery machine, manifold gauge set, adjustable wrench, leak detector, and wire terminals. Always verify system pressure with gauges after reinstallation.
  • Warranty & Shipping: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse. Free shipping on qualifying orders.

Compatibility: Engineered as a direct OEM replacement for the Carrier PY2PEB060090NB packaged heat pump system. Always verify the PSI setpoints on your unit's existing switch and the data plate before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PY2PEB060090NB?
Yes. This is the factory-specified OEM pressure switch for the Carrier PY2PEB060090NB. 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 PY2PEB060090NB?
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?
