York S1-025-32607-000 Limit Switch or if the bimetal discThe York S1 025 32607 000 is a heavy duty furnace high limit switch engineered for precise thermal monitoring within the heat exchanger canopy. This automatic reset limit is calibrated with an opening threshold of 185F and a closing differential at 155F, ensuring the burner circuit is interrupted if internal temperatures exceed safe operating parameters. Featuring a 3 inch insert probe, this component provides accurate real time sensing within the
