Most common repairs + troubleshooting for the Eppendorf 5424R Centrifuge at Acme:

1. LID ERROR (Centrifuge lid cannot be locked or released): This error occurs when the centrifuge lid cannot be properly locked or released. The suggested action is to try closing the centrifuge lid again or switch the centrifuge off and then back on​​.
2. NO RPM/Err 6 (Error in the speed measuring system or drive overheated): Indicates a problem with the speed measuring system or an overheated drive. The device should be left on until the error message disappears, which could take up to 6 minutes​​.
3. Err 7 (Drive fault): This error message suggests a drive fault. If this error appears, the run should be repeated, and if the error message appears again, the centrifuge should be switched off and then back on again after more than 20 seconds​​.
4. Err 8 (Drive overheated): Indicates that the drive is overheated. To resolve this, allow the drive to cool down for at least 15 minutes​​.
5. Err 18 (Major deviation in speed check): This error suggests a major deviation in the speed check. The rotor needs to be stopped and then tightened​​.
6. Err 19 (Electronics error): Indicates an electronics error. The recommended action is to switch the centrifuge off and back on again after more than 20 seconds​​.
7. Err 20 (Too high temperature deviation from set value in the rotor chamber): This error indicates a significant temperature deviation from the set value in the rotor chamber. To resolve this, check the settings and ensure unhindered air circulation through the air slots​​.
8. Err 21 (The temperature sensor on the condenser is faulty): Indicates a fault with the temperature sensor on the condenser. The centrifuge should be switched off and back on again after more than 20 seconds​​.
9. Err 24 (Cooling unit fault, e.g., overheated): This error message indicates a fault with the cooling unit, possibly due to overheating. Allow the centrifuge to cool down and repeat the run​​.
10. General errors (No display, The centrifuge lid cannot be opened, The centrifuge cannot be started, Centrifuge shakes when it starts up): These are various operational issues, including power connection problems, issues with the centrifuge lid not opening, or the centrifuge shaking upon startup. Solutions involve checking the power connection, fuses, and ensuring that the centrifuge lid is closed and the rotor loaded symmetrically​​.
