York S1-3500-3151/A Limit Switch or a capacitance reading outsideThe York S1 3500 3151 A Limit Switch is a critical safety component engineered for precise thermal regulation within HVAC furnace units and air handling systems. This specific high limit safety control operates with a fixed temperature range of 55 155F, acting as a primary safeguard against heat exchanger overheating. Featuring automatic reset functionality, the switch restores the electrical circuit once the internal temperature drops safely below
