My 3 year old Ravenheat boiler won't fire up. The fan, pump etc have all been tested and all seems o.k.
If I wire the pump to a separate supply the boiler fires up and works as normal.
I think there's possibly a fault in the control thermostat switch.
Anyone any ideas before I buy one or get someone to look at it?
