What to do if my Drucker Diagnostics 642VFD-Plus rotor does not spin freely?
- DDavid HuffmanSep 7, 2025
If the rotor of your Drucker Diagnostics Laboratory Equipment does not spin freely, ensure the unit has power and the lid latch is turned completely clockwise to its stop position. The latch makes contact with a switch underneath the front top of the cabinet. If this switch is not activated, the light will not turn on and the machine will not run. Also, check for any obstructions in the rotor chamber. If there are no obstructions, contact Drucker Diagnostics for further assistance.
