This board is for the controller on a house water heater.
In the center of the picture, notice the yellowish color in the vent grooves on the top of the capacitor. That color is not a reflection from the yellow wire near the capacitor. The color is actually in the groove. The same color is on the cap on the right side of the picture too, but it does not show up as well. I don't think I have ever seen something like this before...
Generally speaking, is that a sign of venting?
