There’s Always a Reason

Furnaces don’t just shut off abruptly because they feel like it. Pretty much in every situation, there’s a root cause to the furnace shutting down and we need to diagnose it. Then, we can get to work fixing it, or even replacing the faulty component that caused the problem in the first place.

  • Overheating. Sometimes, when a furnace shuts down at a moment’s notice, it’s due to the system overheating. The flame inside of a furnace produces a lot of heat, but that heat is not intended to stay inside of the system itself. It’s meant to go to the rest of your house and even out. If the blower fan system isn’t working, or if you’ve got a clogged air filter, that heat might stay inside of your furnace and cause it to heat past the point of safety when it shuts down.
  • Faulty ignition. If a furnace doesn’t quite shut off but simply won’t start in the first place, it could be due to a faulty ignition. Just like a car, your furnace needs ignition to ignite the flame and create heat. If there’s an issue with that unit, whether it’s a pilot light or an electrical ignition, it won’t provide your home with heat.
  • A problem with the gas line. There are complex sensors in your furnace that can detect when gas is going into the system if it shouldn’t be. This can cause your furnace to shut down completely to avoid a gas leak or other fire hazard. Your furnace could simply be reacting to a problem with your gas line which requires professional support anyways.
  • A safety concern. Most of the time, a furnace will shut down due to some internal sensor or component that risks an unsafe or unpractical operation. Whether it’s a cracked heat exchanger or a leaky fuel injector, these are all cause for concern. Do yourself a favor and contact a professional for repairs.
