if your boiler works o.k if you leave it off for a period of time , it sounds like you do have a pcb problem , but check what voltage you are getting to the boiler , i had a similar prob' some time ago max voltage to property should be 253 volts . in my case got 260 volts pcb would overheat & shut down .cool down & than work for a while e.t.c .
