Most modern-day furnaces have a bunch of different safety mechanisms to ensure that they run properly. For instance, the heat exchanger keeps the system from accidentally allowing carbon monoxide and other fumes to enter the breathable space of your home. Other components, like the electrical ignition, make sure that the system is in charge of whether or not a flame gets lit, so it doesn’t accidentally run for longer than it needs to.
But here’s a question: how does your furnace know if the gas inside of it is being burned? After all, can’t it accidentally leak gas through a burner system that’s not functioning correctly? And, as we all know, gas is expensive. Well, there’s a component that helps regulate this process and keeps your home from encountering a dangerous gas leak. It’s the flame sensor, and this blog post will be dedicated to describing what this component does, and why you might need it fixed with furnace repair in Lake City, FL!
