York S1-026-34027-000 Roll Out Switch This sensor utilizes a high-accuracyThe York S1 026 34027 000 Roll Out Switch is a critical furnace safety limit designed to detect abnormal combustion conditions. As a specialized bimetal flame rollout limit switch, it monitors the burner area for escaping flames or "rollout" caused by heat exchanger failure, restricted venting, or flue blockages. Rated for 300 degrees Fahrenheit, this manual reset switch terminates the electrical circuit to the gas valve when thermal thresholds are
