Access Fuses/Remove Cover on Beckman Microfuge 20R

I have a Beckman Microfuge 20R that I believe has a blown fuse. It's not possible to access the fuses without fully taking the cover off of the centrifuge, and I can only get the cover part way off at the moment. Has anyone replaced a fuse on this model of centrifuge? Or been able to fully remove the cover for other maintenance/repairs? I've searched around a lot and can't find any good info published online anywhere.

What part of the cover are you talking about? The front panel screws are readily accessible from the front and underneath the front panel. Don

I think you're referring to the 22R centrifuge, which does have a separate front panel that's easy to access. I have a 20R, which has a full cover that comes off together as a single piece. I can get the cover partway off, but it seems like the placement of some of the internal parts is what is preventing me from taking it fully off.

You are correct. I believe that the biggest issue with getting the cover off is that there are cable clamps and ties that are meant to keep things held in place. most of them can be carefully cut free. Most of BCI's benchtop centrifuges were made to European standards so generally there is NOTHING loose inside of the covers. Cutting them free should not cause any harm as the drive motor is no where near the front cover cabling. Don

I got your query so what you have to do to access the fuses or perform maintenance on your Beckman Microfuge 20R, you will need to fully remove the cover. Make sure to check for any latches or screws securing the cover that need to be fully disengaged. If you are unsure, refer to the user manual for step-by-step instructions on cover removal and fuse replacement. If you still have trouble, contacting Beckman Coulter's technical support would be best. They can provide specific guidance for your model and help with any difficulties you encounter. Always prioritize safety by ensuring the centrifuge is powered off and unplugged before starting any maintenance.

After retiring from BCI after almost 33 years as a Field Service Engineer I can tell you that product support has strict instructions about not telling customers how to gain access to the insides of ANY product they sold because of possible liability issues if someone injured themself following their instructions. Also, with rare exceptions the operator's manuals did not provide that information either and I never was allowed to do so over the phone either. It had nothing to do with generating service income but it sure did have everything to do with keeping my job. Don
