York S1-025-38585-000 Limit Switch preventing vibration-induced hardware failureThe York S1 025 38585 000 Limit Switch is a critical safety component designed for precise thermal regulation within HVAC systems. This automatic reset limit switch features a single pole single throw (SPST) configuration, engineered to open the electrical circuit at 55F and close at 45F. For veteran techs troubleshooting York, Coleman, or Luxaire units, this part acts as the primary defense against heat exchanger failure by monitoring temperatures
