There could be a number of reasons why your boiler won’t light. Most boilers use a pilot light to ignite. This is a small blue flame that burns underneath the boiler at all times and lights the burners that provides power to the boiler when the heat is turned on.

If the pilot light goes out, you can relight it. Learn how here. However, if your pilot light keeps turning off, the problem may be with the thermocouple. Learn more about this here.
