Trane SWT2685 Limit Switch R-407C Reduces nuisance tripping in turbulent

Reduces nuisance tripping in turbulent tanks through a factory-set 3-second time delay

This kit specifically replaces legacy part numbers SP12556 and AP12556-2

it provides the consistent torque and static pressure handling necessary for high-static MOD 08 and MOD 10 units

and THT01235

those components must be sourced separately or as part of a complete inducer assembly

Trane SWT2685 Limit Switch R-407C Reduces nuisance tripping in turbulentThe 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 155F to prevent thermal overload of the inducer assembly and heat exchanger, automatically closing at 95F once safe operating temperatures are restored.
