Gas Leaks

Gas leaks are very dangerous. So, if you believe you have a gas leak problem, it needs to be taken care of as soon as possible. Find a furnace repair company, and services in many other locations, can help with any worries you might have regarding a leak from your furnace. The best indicator of a gas leak is the smell of gas. If you happen to smell it anywhere in your home, especially near the furnace, the first thing to do is remove any open flame you may have in your home, like candles, matches, cigarettes, etc.

The next step you can do is shut off the gas supply to your home. Typically it is found near the gas meter, at the gas inlet pipe. You will need a wrench or a pair of pliers. IT is fairly simple to do, just turn the valve one quarter of a turn, so it is perpendicular to the gas pipe. Call your gas utility company and a heating expert to deal with the rest of the problem.

No Flame

If your furnace is simply not working, meaning there is no flame, you need to know what kind of a furnace you have. Older models usually have a pilot light, while newer ones tend to be operated by electronic ignition systems.

With pilot lights, the most common problem is a faulty thermo-couple which should keep the flame going. Essentially, it heats up the furnace enough before releasing the gas into the chamber. If it’s broken, the gas is not released, and the furnace doesn’t work. Keep in mind that although you may identify there is a problem with your pilot light, replacing it is a job for a professional.

When it comes to electronic ignition, you need to turn the switch off before you try anything. IF your furnace doesn’t have one, turn the thermostat completely down for the same effect. Turn it back on so you can watch the whole process and identify a potential problem. Listen to hear a sound of the spark, or alternatively watch the hot surface ignitor start glowing, depending on the furnace. If you don’t see or hear anything, you have identified the problem. Forward this information to your furnace maintenance company.

Check the Fuel Supply

If neither of those is your problem, you may just be experiencing fuel supply issues. All non-electric powered furnaces require some kind of fuel. Whether it is gas or diesel or any other fuel, you need to provide a steady supply of it to function properly. If there’s a break or an issue with the fuel supply, your furnace will not work as well or at all.

First of all, check for leaks in the supply line. Most fuels used by furnaces have strong and mostly unpleasant odors, so you won’t have much difficulty determining if there’s a problem. If it’s not a leak, you may just be out of liquid fuel in your tank, or there is a clog in the fuel line. Check the fuel level in the tank, and the fuel lines leading to the furnace. When it comes to gas, make sure that your gas line is open. The valve should be parallel with the gas line.

Even though you can establish that something is wrong with your furnace, don’t risk making the problem even worse by attempting a DIY repair. Call a professional to help you with the repairs.
