Why does my boiler pilot light keep going out?

Hear this out loudPauseUsually, a problem with the thermocouple causes the pilot light to go out. The thermocouple is the small copper rod that the pilot light hits. Common thermocouple problems include: Dirt/soot on the thermocouple– Any buildup on the thermocouple can block the flame, preventing it from being properly heated.

Why does my boiler light keep going out?

Older boilers may have a permanent pilot light which needs to stay lit in order to light the larger burner within your boiler. If this light keeps going out there could be a faulty thermocouple that is cutting off the gas supply. Alternatively, there could be a deposit build-up or a draught blowing the light out.

Is it bad to have a boiler problem?

A sudden issue with your boiler is never ideal. There are few things more inconveniencing than having to go without the heating and hot water you need for your home. Below we list some of the most common boiler issues and outline their potential causes.

What should pilot light look like on old boiler?

If you have an older boiler that is powered by gas and contains a pilot light, check this. This should be burning a bright blue; if this is not the case it will need to be re-lit (we recommend asking a professional to do this, but instructions can be found online if you wish to attempt it yourself).

Why does my boiler not fire when hot water is on?

There are a few major reasons why your boiler won’t fire for central heating and hot water, the most common of them being issues with: 1 The power supply 2 The gas supply 3 The boiler timer 4 Trapped air in the radiators 5 A frozen condensate pipe 6 A faulty diverter valve 7 The pilot light 8 The pressure 9 A faulty boiler burner

Why is my boiler not producing hot water?

If the pilot light has gone off, this means that your boiler will not produce hot water. If you have an old boiler, you might be able to spot the pilot light through the frame of the unit. In this case, it may be possible to see if the light has gone off.

Can a gas boiler pilot light go out?

However, older combination boilers, which can be found in rented apartments or antique homes, can go out. If you have a modern pilot light that’s gone out, you should contact a professional to relight it. But, if you have an older gas-boiler pilot light, you can relight it with these simple steps.

if the pilot flame looks strong after relighting it this may be ok, if its weak there could be a blockage as breezer suggests, there is usually a thermocouple device that enters part of the pilot flame that keeps the pilot gas feed flowing, if this is faulty that could be the problem.

What happens if the pilot light is not working?

The pilot light will ensure that the gas is constantly being burnt and producing the heat we desire. However, if the pilot light is not working then the same amount of gas will still be fed through the pipe and will continue to accumulate – which of course is dangerous.

Where is the pilot light on my furnace?

Locate the pilot light and look for the tip of a copper rod very nearby. That’s the thermocouple. Can’t Find the Pilot Light? If you’re having trouble locating the pilot or thermocouple, double-check to make sure your unit actually has a standing pilot light.

Why does my gas light keep going out?

There are three reasons why your thermocouple might be malfunctioning: A broken or burned out thermocouple won’t detect the flame properly, effectively closing the gas valve until you replace it. Replacing a broken thermocouple is cheap and relatively easy if you’re mechanically inclined.

Why does the pilot light keep going out on my boiler?

If something is obstructing the flue, the pilot light can go out as the burnt gas has no way of escaping. The gases will build up and extinguish the flame. A faulty or blocked gas valve could also be the problem.

What do you need to know about pilot light?

The pilot light flame needs to completely envelop the top of the thermocouple rod so it knows the flame is on. If the thermocouple isn’t lined up correctly, it won’t read the flame, and will shut the valve for the gas. I’m not touching it. Help me!
