Drain Red Light going off on Geothermal - suspect blown drainage pump

Geothermal has been working great for some time now, unfortunately red drain light now coming up and unit shutting down. Doing construction here yesterday and saws kept blowing the fuses in the house. I suspect I fried the motor in the small drainage unit that sits on the floor next to the geo. It is about the size of a big shoebox and has a black bottom and a white top. Does anyone know what that unit is called and where I can pick one up. Many Thanks.

It may be a condensate pump...that is what it sounds like anyway....
