OEM Carrier High Pressure Switch HK02ZA395 — 395/295 PSI for Model PY1PJB048130NBAA

This is the genuine OEM Carrier high pressure safety switch (part number HK02ZA395), factory-specified for the Carrier PY1PJB048130NBAA packaged unit. The high pressure switch is a critical refrigerant-circuit safety device: it continuously monitors refrigerant discharge pressure and cuts power to the compressor if pressure exceeds the rated cutout threshold, protecting the compressor from catastrophic overpressure damage. When this switch fails or trips without recovering, you'll experience repeated compressor lockouts, fault codes indicating high-pressure trips, or an air conditioner that short-cycles and shuts off on warm days.

  • Specs: Opens (cutout) at 395 PSI | Closes (reset) at 295 PSI | 6(6)A @ 240 VAC | 1/8"-NPT fine thread refrigerant port | Quick-connect electrical terminals | Sensata PS80-03-0018 body | PMAX 41 Bar
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not an aftermarket approximation. OEM pressure switches are calibrated to exact cutout/reset tolerances. Off-spec generics can trip at the wrong pressure, leaving your compressor unprotected or causing unnecessary nuisance lockouts.
  • Install difficulty: 3/5 — Refrigerant-side work. A licensed HVAC technician must recover refrigerant before replacing this switch on a live system. Tools needed: refrigerant recovery machine, manifold gauge set, 1/8" NPT tap wrench, multimeter (continuity test), and torque wrench. Always leak-check the port after reinstallation.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3PM local time.

Compatibility: Direct OEM fit for Carrier model PY1PJB048130NBAA packaged units. Also supersedes legacy part numbers 312926-217, 71267D1, HK02ZA380, HK02ZA396, HK02ZA400, HK02ZA401, HK02ZA435, HK02ZA500, and HK02ZA501. Always verify the PSI cutout rating on your unit's data plate before ordering. Have a fitment question? Our HVAC parts specialists are available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PY1PJB048130NBAA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PY1PJB048130NBAA. 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 PY1PJB048130NBAA?
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?
