Genuine Trane & American Standard SWT03623 Low Pressure Cutout Switch 

Protect your air conditioning or refrigeration compressor from catastrophic failure due to low refrigerant pressure with the Trane SWT03623 cutout switch. This is a critical safety component that automatically shuts down the compressor when the pressure drops below a safe threshold, preventing overheating and inadequate lubrication. It is designed as a direct OEM replacement for various Trane and American Standard units. 


Key Performance Features:

  • Compressor Protection: Safeguards the most expensive component of an AC system by halting operation when refrigerant pressure is too low.
  • Automatic Reset: Once pressure returns to a safe level, the switch automatically resets itself, restoring system operation.
  • Precision Actuation: Factory-set to open at 250 PSIG (Pounds per Square Inch Gauge) to ensure proper safety thresholds are met.
  • Broad System Compatibility: Used across a wide range of Trane commercial and residential AC systems (THC, YSC, TSC models).

  • Pressure Setting: 250 PSIG open

Cross-Reference & Compatibility for the SWT03623 directly replaces or cross-references with these part numbers: 

Trane / American Standard:

  • SWT3623
  • TRNSWT03623 


Troubleshooting Guide:

  • Symptom: AC unit shuts down on a hot day, and the compressor is hot to the touch.
  • This is often due to low refrigerant levels, which causes the SWT03623 to trip.
  • Safety Warning: A tripping low pressure switch nearly always indicates a refrigerant leak or another system issue. Replacing the switch will not fix the underlying problem. A licensed technician must recover refrigerant and repair the leak before charging the system.
  • Pro Tip: This switch has lead wires for connection and an automatic reset feature, so you won't find a button to press on the switch itself.
