Diode

Hi all, i m new here so please be gentle! I've got a circuit board. And a diode looks damaged, thank you.

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.
