Potterton Range none condencing boiler, when running hot this works ok but when calling for heat nothing happens.
Before the heating side packed in their was a buzzing noise coming from the timer clock, which when banged started the heating up again until now. No buzzing noise and no heating but hot water working ok.
I suspect that the clock could be faulty and wanted to know how do i put a loop in to bypass the heating side to test if this is the problem.
Any ideas on what could be causing it and if it is the timer are they hard to replace. THANKS IN ADVANCE.
