OEM Carrier High Pressure Switch 670/470 PSI for Model PH4ANG060000BBAA

This is the genuine OEM Carrier high pressure switch (part number 312926-252), factory-specified for the Carrier PH4ANG060000BBAA 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 if pressure exceeds the safe operating threshold, protecting the compressor from catastrophic damage due to overcharge, restricted airflow, or a failing condenser fan motor. When this switch fails or trips without resetting, you'll typically experience compressor lockout, nuisance fault codes, or an outdoor unit that shuts down shortly after startup.

  • Specs: Trip (open) pressure: 670 PSI | Reset (close) pressure: 470 PSI | OEM Part Number: 312926-252 | Genuine Carrier factory part
  • OEM vs Generic: OEM switches are calibrated to exact factory PSI thresholds. Aftermarket alternatives may trip outside specification, leading to either inadequate compressor protection or chronic nuisance lockouts that mask other system issues.
  • Install difficulty: 3/5 — Refrigerant circuit access is required. This repair must be performed by an EPA 608-certified technician. Tools needed: manifold gauge set, refrigerant recovery equipment, wire terminals, and a torque wrench. Always recover refrigerant before removing the switch.
  • Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as a direct OEM replacement for the Carrier PH4ANG060000BBAA 5-ton packaged heat pump. Verify the part number on your existing switch label before ordering. Our technical team is available to confirm fitment — reach out before you buy if you have any questions. In stock and ready to ship today.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PH4ANG060000BBAA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PH4ANG060000BBAA. 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 PH4ANG060000BBAA?
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?
