Hello
When central heating reaches temp burner cuts off but then continues to ignite then go out until i turn the boiler off. I then have to wait until cold before lighting again.
I have just fitted a new PCB fan board but problem still there. I have been told it may be the CH thermister?. Many thanks if you could help.

I have the same problem with my boiler. Had several engineers out to no avail. Did you get your problem resolved? Do you know what could cause it? I think I've had pretty much every part in my boiler replaced and it is still happening.
