Trane SWT2685 Limit Switch

Trane SWT2685 Limit Switch

The Trane SWT2685 Limit Switch (also identified as SWT02685) is a critical OEM replacement bimetal disc specifically engineered for inducer motor temperature monitoring in Trane and American Standard gas furnaces. This SPST auto-reset switch is calibrated to open the electrical circuit at 155°F to prevent thermal overload of the inducer assembly and heat exchanger, automatically closing at 95°F once safe operating temperatures are restored. Designed for airstream mounting, this component features tin-plated brass quick-connect terminals for reliable signal transmission and is a direct factory update for older SWT2685 and SWT-2685 variants often found in AUC and TUC furnace series.

Key Benefits for Technicians:

  • Precise Safety Calibration: Fixed temperature setpoints (155F Open / 95F Close) ensure strict adherence to manufacturer safety protocols.
  • High Electrical Compatibility: Rated for 120V applications with a 5.8 FLA current rating and 34.8 A locked rotor current.
  • Universal Compatibility: Fits a wide range of models including AUC040, AUC080, and AUC120 inducer housing assemblies.
  • Robust Bimetal Construction: Built to withstand consistent cycling in demanding commercial and industrial HVAC environments.
  • Standardized Mounting: Features an exposed bimetal disc for rapid response to airstream temperature fluctuations.

Common Questions:

Is the SWT2685 compatible with manual reset systems?
No, this is an automatic reset inducer limit switch. If your system requires a manual reset rollout switch, this part will not be a compatible substitute due to the difference in resetting logic and safety function.

Can I use this switch in non-Trane systems?
While the electrical specs are UL and CSA recognized, this is an OEM Trane replacement part. It is exclusively recommended for Trane and American Standard equipment to ensure the mounting footprint and temperature tolerances match the original design.

What are the signs of a failing inducer limit switch?
Common indicators include furnace short cycling, the inducer blower running continuously without ignition, or the unit staying locked out even after the inducer motor has cooled sufficiently.
