Amana-Goodman 1370915S Limit Switch 30°F-230°F

The Amana-Goodman 1370915S Limit Switch is essential safety part used in heating appliances including furnaces and HVAC system units. This limit switch is a thermal control part which protects the system or the neighbouring property from heat and potential damage. Its main use is to measure temperature in the furnace heat exchanger or other areas of interest. The switch is designed to work only in a certain temperature range, in this case, from 30 to 230 degrees Fahrenheit. If the temperature in the monitored area goes beyond the set upper limit of the temperature, 230°F, the switch breaks the electric circuit to the heating system which will stop the burners and avoided an increase in temperature.
