As the title states, I am trying to repair a completely dead centrifuge.  Fuses are good and power gets to the connectors on the board, but there is no display, fan doesn't turn, no signs of life whatsoever except the green LED on the frequency control board flickers every so often, but that's it.  

I assume that the correct fix is to replace the frequency control PCB, but has anybody had any luck repairing them?  Thanks.

I have the same issue on a unit i am repairing.  Did you ever solve this?

Also do you find that the click noise maker goes off as the units capacitors are finally running out of charge following a power off?

Any advice or help is appreciated.

 

Thanks,

Tom

Hello.. yes I repair the boards.  The symptoms you describe indicate board issues.  I would also check your motor bearings.  These often need replacement/rebuild.

I am offering you a source that can help with repairs on the board.  I advertise where to reach me, as I find it easier to verbally describe my findings as opposed to typing it all down.   I have invested much of my time in repairing and research of these boards, and am not opposed to helping others repair.
