Thank you for your reply!I wishI had a service manual!!!
With that said,I set the centrifuge to 4*C from 25*C. It only took 30 mins to acheive 4.4*C. It maintained for 3 hours, uninterreuptedbefore closoning time. No rotor installed to do this vacuum check. No errors or faults popped either.
I believe it may be the rotor itself. I will acquire the rotor today from the researcher, as she keeps it locked in her office.
Moving forward, what more canI do at this point? Especially, if the TEMP 503 comes back.... I have no other way to get the part number than to remove the "fuge" from the lab to diasassemble it to find the pump (I assume) and to get the part number from it.
If you could provide any more guidance and/or serive manual that would speed up my reaction time on this work order.
