Why is my Drucker Diagnostics 642E Laboratory Equipment lid not opening?
- MMegan WilsonAug 6, 2025
The lid may not open due to several reasons: * **No power**: Check the line cord, the circuit breaker on the underside of the centrifuge, and the wall outlet. * **Lid knob ajar**: Rotate the lid knob fully clockwise before pressing the ‘OPEN’ button. * **Lid lock active**: Press the ‘OPEN’ button to deactivate the lid. * **Lid tray unplugged or defective/PCB damaged**: Requires service. * As an alternative, you can remove the ‘OPEN/CLOSE’ sticker and slide the lid latch lever toward the front of the centrifuge to unlock the lid and access the rotor.
