Tip & How-To about Eppendorf 5415d 5415-d Centrifuge W/13200 Rpm Rotor Model F45-24-11
This unit gets a power supply issue once it is getting a bit old and either returns an error code or does not boot.
On the mother board there are two electrolytic capacitors near the 7805 regulator that have probably dried out. You can confirm this with an ESR meter to measure the cap values in capacitance and resistance. Replace the two caps and retest.
The motor drive power module will need to be unbolted and peeled back to access the underside of the caps to desolder them.
