hi. just wondering when fault finding on a boiler ( in general)where ch or hw is on off on off and not requiring reset then overheating or flame detection issues not the problem as the boiler would go require resetting if any of these two occurred so would be looking at other issues causing on off on off problems ie boiler cycling, pcb,thermisotrs etc. just trying to get a grip on on what i can eliminate when fault finding on off on off problems. cheers
