When the thermostat sends its signal to the furnace, the furnace gas valve opens and ignites the burner component beneath the combustion chamber. The gas valve works with the thermostat to regulate the amount of gas that flows into your furnace.
Schedule a professional tune-up every fall (before you first turn on your heating system). They will be able to test your heat exchanger for cracks, clean your pilot light, inspect the ventilation system, and much more.
Periodically check the furnace flame color and characteristics (about every month or so when you check the filter). The furnace flame should be blue with perhaps a small yellow tip. Any other color (red, orange, green, etc.) indicates a fuel/burner problem. Contact a professional to fix the flame color. Do not try to fix it yourself.
