Hi. We have a Sorvall Discovery 100 (not SE). The temperature control system seems off. When we set the temperature to 4C it overcools (the Peltiers are continuously powered to cool). However, if we set the temperature to 15C it switches off the cooling. This suggests the high and low pots need adjusting. Can someone tell us which pots control the high, low and range for cooling. (Note: We have found that VR25 controls the overall temperature reading on the display and have calibrated that reading to an external probe inserted into the rotor once cooled).
If not does anyone have a circuit diagram or service manual they can upload as pdf or email?
Thank you for your help. RE: Sorvall - Discovery 100
