Trane SWT03031 High Limit Thermal Switch – Genuine OEM (190°F / 160°F)

The Trane SWT03031 is a critical thermal safety limit switch designed for Trane and American Standard HVAC systems. Its primary job is to protect your home and equipment by monitoring the furnace temperature. If the system reaches a dangerous 190°F, the switch automatically "opens" to shut off the burners. Once the system cools to a safe 160°F, the switch "closes," allowing the furnace to reset and resume operation.

As a genuine OEM part, the SWT03031 ensures your furnace maintains its factory safety ratings and operates exactly as engineered.


Key Features & Benefits

  • Thermal Protection: Acts as a fail-safe to prevent heat exchanger damage and fire hazards by stopping the system during an overheat event.
  • Automatic Reset: Self-resetting design (160°F Close) means no manual intervention is required once the system cools.
  • Genuine OEM Quality: Replaces common manufacturer numbers like C340366P15 and L190-30F with factory-level precision.
  • Universal Quick-Connect: Features standard terminal types for a fast, secure DIY or professional installation.

🛠️ HVAC DEPOT Pro Tip: Is Your Limit Switch "Tripping"?

If your furnace is short-cycling (turning off before reaching the thermostat setting), your SWT03031 is likely doing its job. Before replacing it, check your air filter. 90% of limit switch "trips" are caused by restricted airflow from a dirty filter or blocked vents. If the filter is clean and the furnace still shuts down, the switch may be "weak" or failed and requires immediate replacement.
