About the Thermostat

The furnace or air handler thermostat monitors the heat being generated by the unit and will shut off power to the heating circuit if the temperature gets too high. A defective thermostat may not allow the unit to heat the air at all. You can use a multimeter to test the thermostat for electrical continuity, a continuous electrical path present in the component. If the thermostat tests negative for continuity, the part should be replaced.
