Symptoms of a faulty gas valve


The gas valve regulates the gas flow from the gas supply line into the heating unit. A faulty gas valve might be the problem if your furnace is not generating heat. This unit could stop working correctly for several reasons. The valve may be old or damaged due to basement flooding or submersion. Alternatively, one of the electronic gas ignition components or a problem in the safety circuit may be the issue. The thermocouple may be worn out if your furnace has a standing pilot light. All these may sound technical and confusing. But our team at Boiler Solutions have put up this blog titled symptoms of a faulty gas valve for your awareness.

How do I know if my boiler gas valve is bad?

If your gas valve is making strange noises or your boiler is unusually noisy, it’s a sign that the valve is broken or faulty. If the valve is defective, it will probably make a lot of rattling and humming noises. If this is the case, you should have a qualified engineer look at it to get it running again and ensure it’s safe. Any boiler malfunction can be dangerous, mainly if it involves gas. Modern boilers lock out and display a fault code when they detect a problem.

It would be best if you didn’t attempt to reset your gas boiler. A reset might sometimes make the boiler operational for a few moments before it locks out again. You should only reset your boiler after the problem has been fixed. You can contact a Gas Safe engineer to repair your boiler. Also, did you know that our team has created a blog titled is a leaking condensate pipe dangerous? We seek to keep you updated on topics like these and to ensure that you are safe wherever you are.

Is my boiler dangerous if there is a fault with the gas valve?

A boiler malfunction could be dangerous, especially those that have to do with gas. Most boilers have a lock-out feature that activates and displays a code when it detects a problem. This lock-out function is installed in modern boilers for two reasons. In some cases, the boiler locks out to protect crucial components from damage (for example, if the water supply runs low, the pump has to work overtime).

But, when a gas valve fault is the cause of the lock-out, it is to prevent the possibility of gas leaking into the burner. In this case, the goal is to make the boiler safe; continuing to use it could be very dangerous. You shouldn’t reset your boiler for this reason. Occasionally, resetting the boiler might make it work for some time before the printed circuit board (PCB) realizes the fault is still present and locks the boiler out again.
