Why Do Gas Valves Go Bad?
Your gas furnace is a complex system made up of many components, all working to keep your home nice and warm. Sadly, none of these components is immune to damage, including the gas valve. What are some of the typical causes of gas valve damage?
Water Damage
It’s not uncommon for your gas furnace to develop leaks. Sometimes, your furnace’s gas valve could come into contact with the water, potentially interrupting its functioning.
System Glitches
The gas valve damage you’re currently experiencing could be the result of a disruption elsewhere in the combustion process. After all, no component operates independently.
Routine Wear and Tear
Is your gas furnace a few years old? It’s more than likely that routine wear and tear is what’s causing your gas valve issues. In such a case, replacing the valve will be the only way to put an end to your frustrations.
Gas Valve Troubleshooting: Signs of a Bad Gas Valve
A bad gas valve is more than just a small inconvenience. If you let it get worse, it can pose a danger, not only to your furnace but also to your Atascocita home. Here’s how to know if your furnace gas valve is bad.
Lack of Heat
Is your furnace not heating your home at all? This is one of the most common signs your gas valve has an issue.
When the gas valve isn’t allowing enough or any gas to enter the combustion chamber, no transfer of heat will occur. As a result of these furnace ignition problems, your unit won’t be able to heat your home.
Furnace Ignition Lockout
Speaking of furnace ignition problems, a bad gas valve could trigger your system’s complete shutdown. This is especially the case if you’ve got a modern furnace that has smart sensors.
These sensors monitor your system’s performance. The moment they detect an issue with the gas valve, they could lock you out from operating your gas furnace. You’ll normally see an error code if you try to restart your unit.
Furnace troubleshooting won’t do you any good here. You’ll need a certified technician to perform a manual reset.
Abnormal Furnace Cycle
Paying close attention to how your furnace runs can help you narrow done the cause should an issue arise.
A faulty gas valve disrupts your furnace’s operation because it cannot consistently supply the gas your unit needs. As a result, you may notice the system running for longer periods without delivering sufficient heat.
Gas Leaks
A faulty gas valve can lead to improper furnace gas control, potentially resulting in a gas leak in your home. This scenario is extremely dangerous and presents significant health and safety threats for you and your family.
If you start smelling natural gas or if the carbon monoxide alarm in your Atascocita home goes off, immediately switch off your furnace and evacuate the home. Once you’re safe, reach out to an emergency furnace repair technician.
