One of my STREN 75 (AquaPro) feeders has a problem with the lower motor. The motor that distributes feed to the pond has quit working all of a sudden. No hurry on repairs, as we are freezing up here anyway.

Can anyone give me some advice on repairs and/or unit disassembly? There are a lot of screws in this thing. Any idea what might be the problem?

Thanks,
Ed
