Our boiler has decided to switch off irregularly. Unfortunately it is in the garage which cannot be reached from indoors!
I go out and press the reset button and everything is good for the next few hours. We have had a boiler service and had new "2 bits that can cause this".
I do not know enough about o/f boilers tp try to work what is wrong. Any help would be greatly appreciated - a list of reasons for shutting down even.

Thanks Roger. May not be the same, but gives us a line of attack. Thanks again

I have the same problem and it is caused by the difference in the feed pipe temperature and the return pipe temperature ours is too great a difference so boiler thinks there is a problem and shuts down am waiting for british gas to sort it think it maybe diverter or pump
