21 R error 24

Thermo Scientific Sorvall™ Legend™ Micro¬† 21R Microcentrifuge error 24 at power up. Are there any fixes besides replacing the control board and display?

Does anyone have a copy of the service manual?

Turn centrifuge off, manually open lid by pushing a heavy paper clip through small hole that is in front of the lid, look down inside the latch so you can see the lid switch, switch centrifuge on..push lid switch down with a small screwdriver then release...then down again then release. Remove 4 screws to lift off top case then remove latch assembly and check micro switches.
