Specimen head refrigeration disconnected
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!Reply

Leica CM1900. Solenoids not getting power
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!!Reply
