Universal F61 Compatibility: Specifically designed to fit the full range of Johnson Controls Penn F61 series standard flow switches

and aluminum tubing across all common refrigerants

Precision Threads: Features 1/2" SAE 45

A failed switch typically results in a total loss of power to the furnace control board even when the door is secured

preventing the gradual loosening that often occurs in high-torque submersible motor start-ups

Nordyne 626513R Limit Switch Universal F61 Compatibility: Specifically designedThe 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
