PCI CL-650 chiller issues

[fishmaster]

First, check that you are using the correct fuse (amp rating recomended by the mfg). If you are using one too light, you'll continue to blow fuses because you chiller is drawing more amps that the fuse is designed to handle. If your fuses are correct, I would think you have an electical problem within the chiller. I would get it looked asap as the fuse is designed to blow to prevent more damage to the unit or a fire. Continually feeding fusues through it will only increse the chances of something bad happening.
