A furnace can be a great addition to your home. Decorating a furnace can give your home a unique look and it can be so comfortable to sit by a warm furnace in cold months. Because having a furnace is so comforting and enjoyable, it can be annoying when your furnace is broken. There are many reasons that a furnace can stop working and this article will highlight some of the more common issues that can occur with furnaces and some basic troubleshooting steps you can take to possibly prevent an unnecessary call to a technician.

Dirty Air Filters

Having a dirty air filter is one of the most common reasons that homeowners have issues with their furnaces. When you have a dirty air filter, your furnace will have less airflow, causing your furnace to produce less heat. Soot buildup may also occur and other issues which involve costly repairs. To prevent these types of problems, change the air filter in your furnace every 3 months or so, depending on how much you use your furnace.

Wrong Thermostat Settings

Make sure that your thermostat settings are on “heat” and that the temperature is not a cooler setting. Also, ensure that your thermostat is fully powered and that there is no dust or debris in the casing for the thermostat. If necessary, switch out the batteries in your thermostat to eliminate power as the cause for the thermostat failure.

Check Your Breaker Box

If your furnace is still not working, check your breaker box to see whether the breaker switch has been thrown. This can happen when your furnace draws too much power. If the breaker switch is thrown (or partially thrown), switch it to the fully open position, then snap it back again.

Open Blower Panel

Often, furnaces have a safety mechanism that prevents the furnace from being used if the blower panel is open. Check the panel door of your furnace and ensure it’s closed to prevent an embarrassing visit with the technician.

Check Gas Valve & Pilot Light

If your furnace is still not working, check your gas valve and the pilot light. It’s possible that the gas valve was accidentally turned off. If your gas valve is already on, try turning the gas off for about 10 minutes. After 10 minutes, relight your pilot light and check whether your furnace is working properly.
