Lochinvar & A.O. Smith 100108899 Limit Switch Els PW 17895 The Ranco C21-2014 Temperature ControlThe Lochinvar & A. O. Smith 100108899 Limit Switch is a critical safety component designed for high performance HVAC equipment and water heating systems. Engineered for precision, this L200F manual reset high limit switch monitors internal temperatures and executes a high temperature shutdown if the system exceeds the 200F safety threshold. By interrupting the electrical circuit during an overheat event, it prevents damage to the heat exchanger and
