Genuine OEM Trane SWT02201 low pressure switch. It monitors suction-line refrigerant pressure and shuts down the compressor when pressure drops too low — protecting against damage from a low charge or refrigerant leak. A faulty switch causes short cycling or a compressor that won't run. Direct factory replacement ensures the correct trip point and fit for your Trane system.

Frequently Asked Questions

Does this Pressure Switch fit my Trane OEM Trane Low Pressure Switch — SWT02201?
Yes. This is the factory-specified OEM pressure switch for the Trane OEM Trane Low Pressure Switch — SWT02201. 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 Trane OEM Trane Low Pressure Switch — SWT02201?
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 Trane 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 Trane 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.
