The freezer doesn't work. When it is 'freezing' at the beginning it stays near ambient temperature. The vacuum pump seems to work although we had to replace the oil after a relatively short while. What seems weird is the coolant compressor seems warm, but doesn't seem to be running.

I did extend a run that seemed almost done until the morning so I could go to sleep. It looked like some water made it down to the pump the next morning, but we cleaned all that out. The no-freezing part we noticed on the next run before the vacuum would be on. I need to allocate some time to troubleshoot. It seems like a fairly simple system, much like the lyophilizers I have used at lab.
