Is Your Furnace Failing to Light?

As the weather cools, the last thing you and your family likely want to face is a malfunctioning furnace. If your furnace is failing to light, there are a number of problems that could be the cause. Some of these problems are easily fixed while others may be signs of a serious issue that needs professional attention as soon as possible.

First, Check the Pilot Light

Are you using a gas furnace? If so, then first you should check your pilot light to make sure it’s working as it should. If it’s on but goes out when you try to light your furnace, or it simply won’t stay on when you relight it, then the problem could be a gas valve that needs replacing. In some cases, it’s as simple as the pilot light not being big enough, and the gas blowing out the light.

The reason this occurs is because gas may enter the chamber without igniting right away. When it does ignite, after more gas enters the chamber, the extra force of the ignition blows out the light. This is definitely a problem that calls for an inspection, to ensure you don’t have any gas related problems.

Other Possible Problems

So if you’ve checked the pilot light or if you have an electric furnace, then you are likely dealing with an electrical issue. Even electrical ignitions for gas powered furnaces should spark when the thermostat is turned on, so if it doesn’t you know that you have a bad switch or relay.

When it’s an Emergency

If you smell gas or something similar in the room where your furnace is located, then you should turn off the unit right away, and call your gas company or 911. There could be a leak causing low pressure, which results in your pilot light going out. This is definitely not a situation that any homeowner should ignore though.
