Rheem-Ruud 47-23117-03 Limit Switch CNT03782 is the current manufacturerThe Rheem Ruud 47 23117 03 Limit Switch is a critical OEM replacement safety control engineered to regulate supply plenum temperatures in gas fired comfort systems. This SPST normally closed switch is factory calibrated with an 85 degree F fixed open temperature and a 75 degree F fixed close temperature, ensuring it breaks the burner circuit if internal cabinet temperatures exceed safe thresholds. Designed for maximum reliability in high cycle
