Cracked Heat Exchanger

The heat exchanger is the tubing that is in the heart of the furnace. They have openings at both ends. This allows for the venting of toxic fumes outside and away from your home through the chimney or flue. While the non-toxic heated are is blown into your home. If the heat exchanger is cracked, the furnace will function fine. But it will allow toxic gases to enter your home. If your CO detector is going off or you are regularly suffering from headaches, a cracked heat exchanger may be the culprit.

Problems with Ignition

No matter what type of pilot light your gas furnace has, it can develop problems. If it’s not working properly or the pilot light is out altogether, the furnace may not ignite. Unfortunately, this particular problem comes from a long list of potential causes. So you will need a professional from a furnace repair company in the Dayton, Ohio area to inspect the furnace to find the cause.

Lack of Heat

You find that you have no heat coming from your furnace. If it appears to be igniting and working, then you may have a dirty filter. You may also have a problem with the ignition that you are not picking up on. Also, sometimes the thermostat can be set incorrectly without your knowledge, so check that first. If you change the filter, check the thermostat and still have a problem, contact a pro for help.

Limit Switch Problems

The limit switch is an important safety device in your furnace. It keeps the blower from turning on before the air is warm enough. And shuts it down if the heat exchanger gets too hot, turning off the burner if needed. If the limit switch is not working properly, you may notice tepid air. Coming from the furnace or overheating of the heat exchanger.
