Nordyne 626513R Limit Switch The closed-end acorn design shieldsThe Nordyne 626513R Limit Switch is a critical thermal safety control designed for precise furnace temperature regulation in Intertherm, Miller, and Nordyne heating systems. Engineered as an L200 50F automatic reset limit, this component monitors internal heat levels within the furnace cabinet to protect the heat exchanger from thermal excursions. The 626513R furnace switch is calibrated to open on rise at 200F, immediately breaking the circuit to
