Why Gas Furnace Is Not Working

Faulty thermostats can cause ac and heater issues.

Why gas furnace is not working.

When you discover that the blower is not working on the gas furnace you need to contact a professional to replace it for you. The pilot light going out is one of the most common reasons that a gas furnace fails to produce heat. Essentially blocking heating vents causes your furnace to work harder and longer than it is intended to work and can shorten its life. With an oil furnace check the fuel supply.

But as soon as they stop working it s readily apparent. If you notice that your machine is still giving off heat yet the fan is not running there are several sources you can check. The thermostat itself can be the culprit of a dead fan even if there is heat. Browse helpful items on amazon.

On old furnaces the standing pilot light can go out due to a strong draft a dirty orifice in the pilot burner or dirt in the gas tube. Blocking air increases the air pressure in your air ducts which may both cause and worsens airflow leaks particularly at joints and seams. What to check if your furnace won t work the problem is that modern gas furnaces are both more efficient and more complicated than those from over a decade ago. Or the thermocouple might be faulty causing the gas supply to shut off.

Fan does not run but furnace still produces heat. Air conditioners and heaters accomplish their tasks unnoticed when working properly. If your furnace does not have a pilot light move on to the next step. Heat means that there is gas flowing so you can avoid checking the propane again.

Your gas or oil burning furnace must receive fuel to work. If the gas supply to the furnace is disrupted your furnace could potentially be lacking the amount of fuel necessary to ignite. However even many modern furnaces still run pilot lights. If gas or propane flow to this pilot light is interrupted even for a moment the pilot light can go out and will need to be relit.

This is why your furnace won t turn on. The freezing air makes you shiver or the summer heat makes you sweat. What might have once been caused by a troublesome pilot light from a dirty thermocouple now involves smart systems that auto test combustion air inducers electronic ignition sensors pressure switches and exhaust flow monitoring.
