As we head into winter, it's a good idea to learn a thing or two about the machine that will provide us with heat and comfort throughout the cold, winter days—most likely, a gas furnace. The more you know how a furnace works, the better you can troubleshoot it if something goes wrong. And since space heating accounts for roughly 45% of energy bills paid by U.S. homeowners, it's no wonder why people want to know more about how they work (U.S. DOE).
If your gas valve is working fine, but the furnace isn't turning on, check to make sure your pilot light is on. For instructions on relighting the pilot light, refer to your manufacturer instructions or contact a professional.
