How to Repair Gas Valve on Furnace

Fixing a Furnace Gas Valve

You might not know it, but the gas furnace gas valve is actually responsible for keeping your furnace running smoothly. Without this valve, the furnace simply cannot operate properly, causing it to get very hot and very cold quickly and without any indication from the owner. This is why it’s so important to learn how to repair gas valve on furnace. So how often should you change it anyway?

 

Your furnace gas valve is actually one of the most important things to remember in maintaining your heating system and something that needs to be considered when you need to fix a broken furnace. For one thing, it allows the natural gas to move from the furnace to the combustion chamber, from where it is burned. Without the proper operation of the furnace, it would not be possible to heat or cool your home, let alone provide a comfortable living environment. However, before you start thinking about changing your furnace gas valve, there are some things you need to know about it first.

 

In order to understand how to repair gas valve on furnace, you must first understand how it works. Basically, the furnace gas valve works as an air release valve, allowing in natural gas (the most common type) into the furnace but stopping it from escaping at the same time. As you might guess, it does a lot more than just that. It allows gas and air to pass through at the same time, creating a very efficient flow of air within the furnace.

 

Now, the question becomes, why would you need to do so in the first place? There are a number of reasons. For one thing, you don’t want excess gas going out of the furnace. If this happened, you would be able to tell by looking at your furnace’s temperature gauge that something was wrong. This could potentially be a fire hazard, which is why you would need to fix this problem as soon as possible. A malfunctioning gas valve would also prevent the flow of air into the furnace.

 

Before you can fix the valve, though, you first need to find out why it is not working properly. The reason why the valve stops working could be as simple as it is dirty. In order to fix this, you can remove the gasket that is around the gas valve itself and clean it using some penetrating solvent. It would be advisable, of course, to use a professional if you are not familiar with this task.

 

Now that you know why the furnace gas valve stops working, you can now turn your attention to finding a new one. Usually, these are made of either metal or plastic. With some models, you can even replace them by yourself. However, if the old gas valve is still in good condition, then you should buy a replacement one instead. Fortunately, there are a wide variety of options to choose from, so you shouldn’t have any problems at all.

 

When buying a new furnace gas valve, you can go to any hardware store and choose from different models. The important thing, however, is that the model you choose is suitable for the furnace that you own. You also need to take note of the overall efficiency level of your furnace. If it is too inefficient to warrant a new gas valve, then you simply have to repair it and add another one. On the other hand, if it is working properly, then you might consider buying a completely new unit.

 

If you do not want to mess with complicated plumbing work, then you can always choose to install a furnace gas valve on your own. There are two ways to do this, and both of them are simpler than what people usually think. If you decide to buy a new valve, you can check the local hardware store or place an online order so that you can get the right product for your home. By doing so, you will save time and money, so it is well worth the effort.
