Flame failure switch trips after approx 1 hour operation on central heating, resets ok every time.

Had new ignition board due to other problem and this problem apparent befor change, also new sensors fitted.

Does switch act as a trip as well as a reset? is faulty switch the possible problem?

It sounds like your boilers overheating. possible causes are cr*p in the boiler , a blockage or the bypass could be blocked. Hubby was corgi reg when we lived in England. In France now
