[Histonet] Is my Leica CM 1850 cryostat haunted?

We have a Leica CM 1850 cryostat that about once every three weeks to a month, turnes itself off! Has anyone else experienced this? How do I fix it?

Initially, we thought someone after hours was turning it off, maybe someone in housekeeping or a passing med tech. That was not the case.
Later our Biomedical people replaced a capacitor or something in the bowels of the cryostat thinking that may be faulty and contribute to the problem. That did not help either.
Still later, the cryostat was put on its own circuit (No help), and then after that, we tried an uninterruptible power source thinking minor power fluctuations were the cause (no help either).

Anyone know how to fix this problem?. It is disconcerting to walk into the lab in the morning and the cryostat is at room temperature and the OR is going to have a busy day.
