Haha, so I wrote all that for nothing. Well, maybe somebody can benefit.

A diode is a lot more sensitive to heat than a capacitor so it could very well be fried.

Diodes can be pretty generic but there are several different types of diodes. Odds are it's just "regular" (versus Schottky or Zener) with the most important factor being current handing ability.

I can't see the bottom of my board and I don't want to take it apart but most likely it's just a small current normal circuit diode which is pretty generic. That is if it's relatively small and black. If it's on the power circuit for a motor though it could have a higher than normal current rating. Can you see any markings on it? Sometimes the width of the traces on the board can give you an indication of the amount of power flowing through it.
