Nordyne 626434R Limit Switch The Johnson Controls DMPR-RS312 isThe Nordyne 626434R is a critical HVAC replacement part designed for pinpoint temperature regulation in furnace systems. As an OEM limit switch, this component is engineered to monitor high temperature operations, specifically featuring a 160 180F auto limit switch range. This furnace limit control operates on an "open on rise" switch action, meaning it breaks the circuit when the internal temperature hits 180? F (82? C) to prevent plenum overheating
