Welcome to 2 hours help.

Up to 48 hours trouble shooting and coaching on repairs $38 additional if you approve it at that time.

Tell me a lot about your technical background please so that I can coach you most successfully.
I need a well focused, well lit, photo of the unit wiring diagram, taken from straight on, and a few pictures that show the internals of the control panel, along with some distance shots of the chiller itself.
I can mark those up with trouble shooting instructions, and begin work on it in the morning.
Use the 'attach files' link at the bottom left of your reply box to attach the pictures.

Hello again, that was a good choice, it is very easy to freeze one of the chillers and break tubes inside the chiller barrel causing a lot of costly damage, not to mention down time.
Good luck with it.
