Must LNB be sealed?

The little round plastic cover on my LNB is rotting away and is no
longer keeping water out. Would water getting in the LNB cause damage?
Coincidentally or not, I am also having trouble getting any signal. I
don't want to move the dish yet before I make sure.

toast!

Without the cover you might find wasps in there. If water isn't
running into the LNB it will probably be fine.

If you're talking about a BUD feedhorn, then some water getting
in there probably won't hurt it, although it's not a good idea.
As mentioned above, insects might also get in, which is undesirable
(for you, not for the insects).

If you're talking about a Ku LNBF or anything similar, then yes,
water getting in could hurt it. It might work if dried out again,
but then again it might not.
