Repeated failure of primary fuses on Agilent MC 5975C

We are having repeated failures (3 now) were the MS just shuts down.  I can replace the fuses, but I wondering why this continues and if this is indicative of a bigger problem.  I would like some advice how to troubleshoot.  Thanks!

  • Hi Jennifer,

    Soccerdad is correct. Rough pumps as they age will start to draw more current through the AC board on the MSD. The slow blow fuses will run hotter and near their limits. The rough pump replacement should cure the fuses blowing. I would replace the pump as soon as you can as the extra demand can be a strain on the AC board. The new Pfeiffer Duo Rev G is the supported replacement G3870-80055 .
