I have a potterton neta heat boiler which every few minutes makes a clicking noise and the flame keeps going right down then back up again. It stays alight its just annoying and not sure its operating right.

I called a corgi chap and he wasnt sure of the cause!

Any ideas what may cause this?

Take the one screw out and pull the front cover off and check the relay on the panel
