Over the past couple of years I have had to replace the circuit board costing £100 and £150 respectively. This first time was in the heating control circuit and then second caused by the pump not cutting out after 8-10 mins. I replaced the board and everything is fine. I kept this latest board and wonder if there is a circuit diagram anywhere so I could find the faulty component and replace it? After all that circuit, could only be and ON/OFF switch which is more than likely to be a faulty condenser but I don't knwo which one.
Any clues?
