Chiller Died - What to do now?

[Jaws]

Well, one of the worst things that can happen this time of year has happened. My chiller isn't working. It's still on all the time, it tries to pull the temperature down but it just ends up heating the water now instead of cooling it. It tries for about a minute or two with no luck and then makes a big clunking sound like it always did when it shuts off and it's done. Despite the fact that I oiled the fan heavily when I had it apart yesterday and the fan worked perfectly when I put it back together but has since stopped. When I watch it I notice that it does start moving the fan very slowly when it’s turning on but barely. I’ve tried giving it a boost by spinning the fan manually with some forceps or something. It spins fairly easily with help but then stops again. The temperature is steady at 85 and the lights aren't even on yet. What can I do? HELP!
