York S1-025-46404-000 Limit Switch 318518-761 The Johnson Controls KZ-4000-5 isThe York S1 025 46404 000 Limit Switch is a critical safety component designed for precise thermal monitoring within York, Coleman, and Luxaire gas furnaces. This L150 40F limit control operates on a fixed temperature profile, featuring a normally closed (N C) configuration that opens the circuit when the internal plenum or heat exchanger temperature reaches 150F. Once the system cools by a 40F differential, the switch resets at 110F. Reliable thermal
