Chiller help

Does it make any noise when it's powered up? Check to see if the fan is spinning and you should be able to hear/feel the compressor spinning too. If the fan and the compressor are spinning and the chiller is not cooling the water, your refrigerant has likely leaked out. You would need to get the leak fixed and the system recharged. I think JBJ still does repairs on their equipment, it's real pricey to ship a chiller though. Maybe you can get lucky and find a place that does automotive AC and get it done there.

Couple things I can think of off hand are either a thermostat failure (doesn't correctly read the water temp) or a low pressure safety shutoff.  The latter keeps you from burning up the compressor if you run low on refrigerant. Does it display an accurate temp?  If so, the second option seems most likely as I doubt these would have two separate temp senders.

Sounds like a low pressure safety shutoff could be an issue then. Can you tell if your unit has test/fill connections on the refrigeration loop?  If you have ever looked at your car AC you might know what these look like - metal snap-fit connections typically. I ask because, if you do, it's possible to get compressed cans of refrigerant that you can snap on there to refill the system easily. Which might be worth a try. You would have to crack the case open for this so not sure it's up your alley. Unfortunately it seems a lot of these don't have the test/fill ports and the lines are just crimped off at a fill T... which means a more expensive trip to a refrigerant specialist (insert sad face here).
