Hi, working on the CM1900. Driving me crazy.
First problem: bad CFM. Replaced it. Second problem: bad starting circuit on one compressor. Replaced that. Third problem: bad compressor. Replaced that. Now the problem Im having is that the neither of the 3 solenoids are opening up. No voltage going to them in normal operation but do get voltage during test mode. Got a solid 24 VDC input to the circuit board. No voltage at the output. Please help! Thank you so much!! RE: Leica Biosystems - CM1900
how do you charge the refrigerant on a leica cryostat system with 404a and what should the pressures read on the liquid and suction lines
RE: Leica Biosystems - CM1900
We are a research lab at Vanderbilt University that has problems with a Leica CM1900 cryrostat. Our repair specialist has taken ill midway thru repair of our CM1900 cryostat. he has removed and repaired the coarse adjustment motor but has not been able to return it to the instrument. Is there anyone who can recommend a repair service in Nashville TN??
Handwheel on Leica Cm1900 cannot make the full cycle. It is blocked. I could not find answer in the troubleshooting section. Your assistance will be much appreciated.
