Why Is My Pilot Light Yellow or Orange?

A yellow or orange pilot light can be a sign of a carbon monoxide leak and should not be ignored. But how do you know if carbon monoxide is seeping into your property or whether the strange glow from your pilot light is something else entirely? Without boiler cover, you may feel like you have no alternatives but to ring an expensive repairman but there are a few things you can do first. To help you out, we’ve written this little guide:

Why Is My Pilot Light Yellow or Orange?

Is there a breeze hitting your boiler?

Even a slight breeze on your boiler can cause air to get into your gas supply and this may change your pilot light from its normal blue to a yellow or orange colour. This is one of the more common reasons and can be easily fixed by eliminating the draft and making sure any vents and flues are clear of blockages.

Is the pilot valve adjusted correctly?

The pilot valve dictates how much gas is used by the pilot light. Too little gas can cause the pilot light to flicker and change colour. To adjust this, look for a screw near the pilot light. Turn this until the flame turns blue. Make sure you follow your boiler’s safety instructions before attempting this fix.

Make sure your pilot tube is clean

Dirt and grime can accumulate within the tube where the pilot light sits over time. This can disrupt the air and gas balance, making the flame change colour. We would recommend that you get a Gas Safe engineer out to clean the tune rather than doing it yourself and make sure you avoid any do it yourself YouTube videos as rupturing the tube is a distinct possibility.
