OEM Carrier Pressure Switch for Model CH13NA01800GAAAA Unit

This OEM Carrier pressure switch is a safety control that monitors system pressure on your CH13NA01800GAAAA and signals the control board to halt operation when readings move outside safe limits. It guards the compressor against damage from low-charge or high-pressure conditions and ensures the unit cycles only when it's safe to run. Built to exact Carrier specifications, it matches the original trip points, electrical rating, and port configuration for a true factory fit that generic switches can't reliably match. Installation is a moderate DIY job for anyone comfortable around HVAC controls: shut off power at the disconnect, label and transfer the wiring, unthread the old switch from its port, and seat the replacement securely. Most installs take about 30 minutes with basic hand tools. Restoring a genuine OEM pressure switch preserves accurate fault detection and keeps your system protected as the manufacturer intended. This part is in stock and ready to ship — orders placed before 3PM CST go out the same day so you can get back to cooling fast.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier Model CH13NA01800GAAAA Unit?
Yes. This is the factory-specified OEM pressure switch for the Carrier Model CH13NA01800GAAAA Unit. 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 CH13NA01800GAAAA Unit?
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?
