York S1-7710-3281 Limit Switch R404A/R507The York S1 7710 3281 is a critical 105 85F fan limit switch engineered for precise thermal management within residential and light commercial air handlers and furnaces. As a genuine OEM York part, this bimetal sensor ensures the blower fan activates once the heat exchanger reaches the 105F cut in point and deactivates after cooling to the 85F cut out. This specific temperature differential is vital for preventing short cycling and optimizing latent
