York S1-2880-3181 Limit Switch L99H008 reducing unnecessary mechanical wear andThe York S1 2880 3181 is a precision calibrated high limit switch engineered for critical thermal monitoring in residential and light commercial furnace systems. This 160F 30F limit sensor acts as a primary safety control, interrupting the gas valve or ignition circuit if plenum temperatures exceed the 160 degree Fahrenheit threshold. Featuring a 30 degree differential, this component allows for an automatic reset once the heat exchanger cools to 130
