hi all histoneters 
i have learned alot from your posts and i need any suggestion about a cryostat that was
working perfectly until the power cable is pluged off accidently. then after about 2 days i put it again in the power and all is working with its motor sound but no refregration and room temp. not decrease under 20 degrees!!! i let it for aweek but no change!  unfortene the technical service may take long time till it come to see the proplem as it is in a national university ( routine work) and i hope i could do that. any suggestion please?
