Fountain Diagnosis Assistance
If there are any HVAC or similarly certified (or certifiable) folks around feel free to chime in. I made all of the connections and turned on the soda machine (Cornerlius Omega 8 valve manufactured by Wilshire) last night, and after the high-pressure line explosion (clamp came loose and shot the dogs with carbonated water) and 'Christmas Story' incident (CO2 froze the regulators and I touched my thumb to one; had to rip the skin off to remove it) everything worked fine. The compressor came to life and formed the ice bank in about 4 hours, the soda water was nicely ice cold from all eight heads.
Five hours after initial startup, the service light came on. This light only comes on if the redundant ice bank control (Ranco 016) is tripped- which only happens if the temp gets into the ~20 degree range to prevent compressor freeze up. The redundant control and service light can be reset by allowing the ice bank to thaw to above 50 degrees. I let the machine sit for 20 hours and it has finally thawed enough to shut the service light off- however, the compressor still will not turn on (the agitator is still working properly, though). I'm thinking that the primary control (Ranco 018) is bad and should be replaced, but the unit is brand new and looks fairly solid-state. Thinking it might have sat too long (it was waiting to be installed for ten years) and might simply be stuck. I believe it operates in the same fashion as a thermostat . . . might go ahead and take off the primary and see if the switch is stuck anyway. Save $60.

I'm NOT a refrigeration tech, but spent 25 years with a dairy, living with systems of all sizes.
IIRC, a low gas condition can cause the compressor to run and not shut off. Since it was in storage so long, there might have been a tiny gas leak. Good luck. Les

There could be a leak, but I wonder if such a low level of refrigerant would still allow the ice bank to form? It froze within specs (3-4 hours in a 75 degree room).

All of these HUGE brains around here and still no answer?!
Here's what I've found thus far- I can shut the light of by opening the contact on what I believe is the primary ice bank controller. I'm going to crack open the secondary controller and try to shut the light off that way, and I believe that as soon as the secondary control is open the compressor should immediately turn on since the back-up is there to prevent it from running too much. Really wish you all would just start drinking enough diet soda and other such nasty concoctions so that you'd be enticed into installing your own home machines and I'd be able to have a bit of dialogue going here.

It's back up and running after I manually reset the backup control by taking both leads out of the ice bank and warming them by touch. Now the compressor is running again and all is well- if the service light comes back on then the problem is definitely a bad primary control.
Only shocked myself twice while poking around in there . . .
