Agilent 1100 autosampler repair/disassembly

So I have an Agilent 1100 HPLC that has been working great, but I dropped by the lab over the weekend and the autosampler (sitting idle, model no. G1313A) was making a loud noise. I turned it off and back on a few times, the noise persisted, but the status indicator is normal and the logbook doesn’t show any errors. I reached out to Agilent and they said that it sounded like a fan was going out but couldn’t be sure since there were no errors displayed.

Does anyone have experience with repairing a fan going out on their autosampler, or any experience disassembling the autosampler somewhat extensively? I’d like to take it apart and inspect to make sure nothing is caught in the fan and causing it to drag but I’m hesitant to even try due to my inexperience with it. I’ve been reading through the manual and looking on other forums and youtube, but haven’t been able to find what I need yet.


Page 146 goes through replacing the fan, looks pretty standard.

I will add that eventually all things break, need maintenance, or need to be replaced with analytical instruments. Sooner or later you will have to tear something down, and you will not be experienced doing it until you do it. Take lots of pictures and stay organized, you will be fine!

If you really screw it up, you can call an Agilent tech out to fix it.
