Nordyne 626494R Limit Switch This wear washer is engineeredThe Nordyne 626494R is a critical safety component engineered for precise thermal management in residential and light commercial forced air systems. This automatic reset limit switch serves as the primary failsafe, monitoring heat exchanger temperatures to prevent thermal runaway. Rated as a L280 40F furnace limit switch, it is calibrated to open the electrical circuit at 280? F and automatically re close when temperatures drop back by 40? F to 240?
