OEM Carrier Pressure Switch Replacement for Model CH13NA03700GACBA

This genuine OEM Carrier pressure switch is an essential safety control for your CH13NA03700GACBA unit, sensing pressure and stopping operation before unsafe conditions can harm the compressor or coil. When the switch fails, you'll often notice a unit that won't start, short-cycles, or locks out on a pressure fault code even when pressures and airflow are normal. This factory-spec replacement is calibrated to the precise trip and reset thresholds Carrier specifies for the CH13NA03700GACBA, avoiding the nuisance tripping and fitment issues common with universal parts. Using the correct OEM switch keeps your system's built-in protection accurate and dependable. Installation is relatively easy, generally 15 to 25 minutes, but should be handled by a qualified HVAC technician who can verify the tubing, wiring, and confirm there's no underlying pressure problem. Each switch is tested to OEM standards for consistent results. Order before 3PM CST and your part ships the same day from our US warehouse so you can restore safe cooling fast.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier Model CH13NA03700GACBA?
Yes. This is the factory-specified OEM pressure switch for the Carrier Model CH13NA03700GACBA. 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 Model CH13NA03700GACBA?
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.
