I’ve rescued a number of bits of electronic kit which have been out in the rain. The wet doesn’t usually affect the electronics once it has dried out. What it does do, however, is make the chassis go rusty on the inside where it’s not powdercoated or plated. In your case, it might also have drenched the insulation, which is like a dense rock wool in an oven. Worth checking if it’s likely to be a problem.
