Sorry to bring up a long-dead thread, but My JBJ chiller just stopped this morning. It had been working well (great actually) for over a year and then this morning I can't even get the display to light up...it's just dead. Did you ever find out what was wrong with yours? I'm not too happy because the tank it is cooling is a 125 in a greenhouse and it NEEDS the chiller to stay at 80, without it I'm looking at 90+ when the sun really comes out. No losses so far (I've got all doors open and fans running), but I need to do something pretty quickly...Thanks!
