on checking the PCB I found the resistors R114 R35 and R2 totally burn out; I want to have their value to try to change them

I have recently repaired one of our centrifuges. changed slow charging resistor, 15VDC Voltage source and some connectors. I have given it a go at different RPM levels, it is turning, everything looked fine. Then, last day i got a call from the lab assistant. She is saying that rotor turns but we can't separate the samples (blood). What could be the cause of this. Are there any things that i might do to fix this or is it them doing something wrong? Thanks.

Hi there, One of my machines' giving me the "err 1". I have looked it up from trobleshooting part of the service manual and it says that i should either change the "mP board" or "keyboard". Does anyone knows a way around this. All my displays are functioning, i have controlled the tacho using the test function and it works well aswell. Thanks.
