Trane CNT4825 Limit Switch 319847-401 What causes the valve toThe Trane CNT4825 Limit Switch is a mission critical safety component engineered for precision thermal monitoring in residential and light commercial HVAC systems. This 170F SPST N C A R Limit Switch serves as a reliable furnace high limit sensor, designed to interrupt the electrical circuit if internal temperatures exceed the 170 degree Fahrenheit threshold. Utilizing a single pole, single throw (SPST) normally closed (N C) configuration, this bi
