OEM Carrier High Pressure Switch HK02ZA395 — 395/295 PSI for Model PY2PEB036090AA

This OEM high pressure switch (part number HK02ZA395) is the factory-specified refrigerant safety switch for the Carrier PY2PEB036090AA packaged unit. Manufactured by Sensata (PS80-03-0018), it monitors refrigerant discharge pressure on the high side of the refrigeration circuit. When pressure exceeds the cutout threshold, the switch opens to protect the compressor from catastrophic damage. A failed or stuck-open switch typically results in nuisance trips, compressor short-cycling, or a system that locks out immediately on startup with a high-pressure fault code.

  • Specs: Opens at 395 PSI | Closes at 295 PSI | 6(6)A @ 240 VAC | 1/8" NPT fine-thread port | PMAX 41B | Sensata PS80 series | Cross-references: HK02ZA395A, PS80-03-0018, P332-1103, 312926-217, HK02ZA380, HK02ZA400, HK02ZA401, HK02ZA435
  • OEM vs Generic: This is a genuine Carrier factory-authorized part. OEM pressure switches are calibrated to exact cutout/cut-in tolerances at the factory — generic aftermarket units often drift outside ±5 PSI spec, risking either false trips or — worse — inadequate compressor protection under true high-pressure events.
  • Install difficulty: 3/5 — Refrigerant circuit work requires EPA 608 certification. Recover refrigerant before disconnecting the switch port. Tools needed: manifold gauge set, refrigerant recovery machine, adjustable wrench, thread sealant tape. Always confirm system pressure is zero before removal. Reconnect wiring with the correct quick-connect terminals and torque the port fitting to spec.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered for Carrier PY2PEB036090AA packaged units. Also cross-references to numerous superseded Carrier, Bryant, and Payne part numbers — verify your existing switch's PSI cutout rating on the data plate or old switch body before ordering.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PY2PEB036090AA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PY2PEB036090AA. 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 PY2PEB036090AA?
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?
