check the manual - maybe someone (long time ago) set up an auto defrost?

 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.
