Well, nothing is working and I don't have a clue what to do next. The ice trays get cold, but not COLD. I can't scrap this thing. It was my father-in-laws and it has been in their family since my wife was born. Any other suggestions would be welcomed! Should I start shopping around for a new top? Thank you guys for all the help you have given me. I appreciate it! Sorry I had no notifications for this thread for a couple days. I tried viewing the forum on my phone and that seems to have marked all threads as "read" for some reason. The CK compressor requires oil pressure in order to build refrigerant pressure and function. This is operated by a valve inside the unit with some moving parts that could become stuck. Could you make a video of the compressor starting up; and for about 5 minutes of running? Move the camera around the compressor dome and the evaporator as well. After about 5 minutes, video from the top of the compressor to pick up the sound as you turn the power off. It would be helpful to hear the sound from it during these times.

Why not CK's? There has to be a way to do it, right? The sulphur dioxide refrigerant used in a CK does not break down to create non condensible gases. CA's use methyl formate which is very different.
Yep, it's a totally different animal from a CA. All CA's eventually develop some level of NCG buildup because of the chemical properties of the refrigerant. There are really only three ways I can think of, for an SO2 system to have noncondensible gas buildup. One would be a mistake during servicing. Someone could have accidentally put a small amount of some high pressure refrigerant such as R407C in the system by accident (gauge hoses charged with liquid from the last job etc.); or nitrogen could have been put in etc. That would not be your case since the machine was not serviced when this happened. Another would be a leak in the low-pressure side of the system. The SO2 units run in a vacuum while at frosted temperatures. Any small leak (while running) would cause it to draw in air. If this were the case, you would have a refrigerant gas leak while the unit is stopped, and the pressure is up to 50 or 60 PSI throughout the system. Unless you've noticed a strong odor of SO2, this possibility is extremely unlikely. The last explanation is due to some sort of thermal damage to something in the motor, due to the failure of the relay. Some material could have degraded and released some gases into the unit. I would not know mow likely this would be. If the motor was damaged in this manner, I would expect it not to function at all. This would therefore be highly unlikely. Before the relay was changed, you took current readings and saw 3.2 amps if I remember. Have you taken a current measurement with the new relay in place? It would be interesting to see what sort of difference there is now. Does the new relay include a capacitor?

Is the a way to relieve the "blockage" from this unit, since I can not purge it?

Sorry, I didn't see the last reply. It is still at 3 amps. I can here the "fluid running" sound when I start it up. The ice try gets cold immediately then stops cooling after a few minutes.

If there is anybody that can help me fix this unit, please respond. I am willing to travel to a legitimate repairman to get this fixed. Anyone who could lead me in the right direction would be appreciated.
Thank you

Hopefully someone closer would be able to assist, but if that doesn't happen - strap her on a pallet and send this way.
