What You Can Do If Your Furnace Stops Working

As the colder seasons start to creep into East Texas, your furnace becomes one of the most valuable things in your home. However, there are possible instances when your furnace just won’t start up. You become uncomfortable, and then panic sets in because you start to imagine the horrible things that might happen if your furnace still doesn’t work.

Rest assured, with proper guidance and a do-it-yourself attitude, there are a couple of measures you can take to check what’s wrong with it:

Check the thermostat

The first and easiest thing that you can check is if your furnace’s thermostat is working properly. It has to be physically set to “Heat” and is set at a temperature high enough to turn the furnace on. But sometimes the thermostat can stop functioning properly and then the whole system might not turn on.

Check the power

Check your furnace’s fuse box for any tripped or blown circuit breakers. And try to reset it by flipping the power switch off and then on again. Be mindful as a blown fuse could sometimes mean that there is a problem with your electric system. Also check the wires for corrosion or pest damage. If battery-operated, simply replace the batteries.

Is the pilot light on?

For older models, a dead pilot light happens normally. Simply reignite the pilot light at the bottom of the unit. Check also for any clogs in the furnace’s orifices, drafts from windows, and if there is a problem with the furnace’s thermocouple. For electronic-ignition furnaces, simply flip the power off and back on.

Insufficient gas or gas leak

See to it that the gas valve is turned fully on. A possible reason your furnace doesn’t start is because it is fed an insufficient supply of gas. However, if you smell gas around the furnace or in your home in general, do not light a fire or use a switch. In this case, close the gas valve and contact your local fire department from a safe distance for assistance.

Check for a blockage

Make sure there is no debris blocking the intake of air, as well as the exhaust. Call for help if the chimney is clogged.

Check and replace dirty air filters

Naturally, air filters will get dirty over time, and that will reduces the efficiency of the furnace. Ideally filters should be replaced every 1-3 months.
