⚙ Eppenorf Mastercycler Repair

☷ February 4, 2010 ☷

Keywords: power failure
Did your Eppendorf Mastercycler Gradient 5331 suddenly go dead? And it isn't the fuse? And it IS plugged in?

Two of ours have failed in this manner, but the repair costs only about $10.
For the benefit of anyone who may have this same problem, it was the inrush current limiter.

This image shows the location of the current limiter, here labeled SL15 20004 (Amtherm, Inc.)
