Gas Furnace Not Working? Here Are 5 Reasons Why

Gas Furnace Not Working? Here Are 5 Reasons Why

A well-functioning furnace is vital in keeping a cozy indoor atmosphere in your Longview, TX home. But, what if your gas furnace is not working as expected? What should you do to troubleshoot the problem? The first thing to do is to understand the different causes of a malfunctioned gas furnace. Check them out below.

Wrong Thermostat Setting

Check the thermostat if it set to “heat.” The temperature control setting must be above the room temperature for the furnace to kick on. If the unit still refuses to work, you might need an expert technician to examine the issue.

No Pilot Light

Your gas furnace might have failed to turn on due to ignition problems. A pilot ignition light should stay lit while the system is on. If it is clogged or loose, your furnace will not fire up. You only need to see a blue pilot light underneath the furnace and no other colors than that.

Blower Motor Issues

Another important thing to check on the furnace is the blower motor. A flashing green light on the motor means that it is working well. But if the light is red or not blinking, your furnace might fail to do its job this chilly season. Issues on the blower motor are not yours to handle. Call an HVAC pro for inspection and repair if necessary.

Inadequate Gas Supply

A gas furnace requires enough supply of gas to operate. With this, the gas control valve must be fully turned on so the furnace will start working. Any disruption or error on the gas line may disable the system and leave it inoperative.

Dirty Air Filters

Most often, gas furnaces failed to start because of dirty and clogged filters. Well, it would not have happened if you were diligent in cleaning and changing the filters. Dirt can accumulate fast in your furnace that can affect the status of the system in the long run. If you let that happen, your heating system might completely stop functioning any day this winter season. This issue is fully avoidable if you keep your filters clean.
