Based on customer reports and repair data, this part commonly fixes these issues:
The furnace thermostat monitors the heat being generated by the furnace and will shut off power to the heating circuit if the temperature gets too high. A defective thermostat may not allow the furnace 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.
