If your Blacklick home’s furnace isn’t lighting properly and your family is starting to suffer because of it, there are a number of possible problems you should check for before calling a professional. Some of these issues can be fixed quickly by you while others may be signs of a serious problem that needs professional attention right away.
Checking the Pilot Light
If you have a gas furnace, the first step is to check the pilot light and ensure it is still working properly. If the pilot light is still on but goes out when you try to light the furnace or simply won’t stay on when you relight it, you may need to have the gas valve replaced. In some cases, it is as simple as the pilot light not being large enough and the gas blowing out the light.
This happens when gas enters the chamber and doesn’t ignite right away. When it does ignite, which happens after more gas enters the chamber, the extra force of the ignition will blow out the light. This is still a problem and should be inspected to ensure you don’t have any potential gas related issues.
Still Not Lighting
If you don’t have a pilot light or the unit still isn’t lighting, it may be an electrical issue. Electrical ignitions for gas furnaces should spark when the thermostat is turned on, so if it doesn’t you know that the switch or relay are bad.
If you smell gas or anything similar in the room where the furnace is located, you should immediately turn off the unit and call your gas company, followed by a Blacklick heating technician. There could be a leak causing low pressure that results in your pilot light going out. Whatever the case, you need someone to look at it immediately.
Your furnace should always turn on when you flip the switch and if it does not, assume there is a problem. If you cannot find the problem yourself and easily fix it, you should call a professional. The risk inherent in an improperly working furnace (especially gas or oil) is too high to ignore.
