Hello, I have a thomas 2660C-E32 aeration pump that will not run longer than a minute & smells really hot then shuts down. I know it's thermally protected & designed to shut off when hot, I was just wondering what would cause it to overheat? It has the overworked electric motor smell & a humming sound before it shuts down. It started after the system was running then on a hot day the cooling blower fan died, so the pump shut off when it was hot, I replaced the fan with two & the system ran for a week now this? just looking for info if I need a new pump.
