Thanks for the replies. I won't be able to search for a circuit diagram for a few days since I'm currently on holidays. I took another look at the board and the diode in question is identified on the board as "CR 1", "CR2", and "CR3". I believe "CR" stands for control relay. I took a picture as well:

I circled the 3 diodes and I circled the row of capacitors that are directly connected to the Anode of the diodes.

EDIT: I just looked up "CR" and according to one source it stands for "diode".
