Most techs are aware of one or two common mainboards used in GE Arctica and Profile type fridges. The most common I suggest you have in stock as part of my GE Fridge Survival Kit ( see http://appliantology.org/blog/1/entry-730-ge-refrigerator-repair-survival-kit/)

However, the other day I came across another similar board that I wasn't familiar with, or so I thought. Main Board Part no. WR55X10832 I didn't think I'd seen that version before until I found one in my old board collection (I keep many old boards to... uh... to.... uh... hell, I don't know why I have them).

This meant I had replaced this board before and I hope I replaced it with the same board as opposed to the board I keep on stock. Well, I never got a call back on a board replacement so maybe I did but it seems as though I would have remembered this strange part number....

Anyhow, the following is a GE mainboard cross-reference... just make sure to always check the part number even if you think you know the board as they all look quite similar.
