Flashing decimal places flashing at specimen head display temperature. Manual States specimen had refrigeration disconnected. After manual override and verified operation of compressor circuit after jumpering jp1 and s1 in position 3. Circuit does run compressor and fan. After resetting back to position zero and jumpering jp1 again. Same condition persists. Flashing decimal points at plate temperature read out. Any Ideas how to correct this condition to allow for normal plate refrigeration operation? Thanks!

There are two solenoids behind the lower front panel (upper right) of the Leica CM1520 cryostat. One of the solenoids, I presume, is for the defrost circuit. Can anyone tell me what the second solenoid is for? Does anyone have a service manual or any service literature?

Unit sat 3 years. Turns on , microprocessor seems ok. Unit sometimes cools , but not to set -25C . Other times starts and does not cool at all. Is this a condenser problem or a possible sensor/main board issue ?

We have a pretty new Leica CM1950 and the device has a blinking red wrench on the panel. The PM has just been done recently and the device has no apparent issues other than the blinking light. Is there a way to reset this and make it go away?

A client has four Leica CM1950 cryostats. The two older ones are leaking refrigerant in the object cooling system. One has a very slow leak, but the other one is leaking faster and faster. It appears to be in the flexible liquid line. I checked the service manual, but couldn't find a part number. Does anyone know the part number? Has anyone replaced these?
