Trane MOD2686 Stepper Module 320735-701 ensuring a consistent arc forThe Trane MOD2686 Stepper Module (identical to MOD02686) is a critical OEM replacement part designed for precision control in high performance HVAC equipment. This stepper module with motor serves as the driving force for electronic expansion valves (EEV) and precision dampers, commonly found in Trane chillers like the RTAC, Series R, and Sintesis models. By converting digital signals from the main control board into discrete mechanical steps, the
