    It would help if you gave information on the model and year of the Aga. A photo of the entire board, both sides may enable someone to deduce the purpose of the diodes.

    Are you sure the diodes are faulty. They are covered in dried gravy.:) If they are connected to a transformer they could be rectifiers to generate DC for a control circuit. If so, 1N4007 would do. If open circuit, then you will need to determine the right way round to connect.

    Hi, its a Rayburn 400kpf model. About 6 yrs old. It just stopped working. No power to the burner. But power everywhere else to the Rayburn. I just noticed that on the PCB board the diode on the right looks damaged.
