Hi all
been out to this boiler today with customer saying the pilot light keeps shutting off at various intervals. I've never worked on this boiler before and there was no MI's present so hopefully someone can help me.
What seems to be happening is that when the pilot is lit the boiler will work ok on a demand for heating or H/W. However it also seems to be firing up and shutting down repeatedly even when there is no demand at all. Obviously this causes the temperature of the boiler to rise as the heat is not being taken away from the boiler and therefore the O/Heat stat kicks in and shuts off the pilot etc. Now the presure is fine and the fan & pump seem to work ok so not sure if this is maybe a stat fault or maybe the P.C.B? Is it normal for this boiler to cycle with no demand for heat?
Hopefully some of you can help me out as I don't like having to scrap perfectly good boilers due to my lack of knowledge!
