PCI CL-650 chiller issues

[christyf5]

So lately my chiller has been blowing fuses like they are going out of style. At first they would last about a week or so and then I'd come home on friday to find it had blown. I thought it might be due to the heat in the room with the warmer weather but in my old house the temperature in the basement routinely got to 35C (woodstove) and the chiller never had any problems. Then I thought it might be that it was too close to the wall so I moved it. I've also installed a fan to help with circulation at the back of the unit. Still no go. Now the chiller is fine for a few hours then dies at some point. The unit is a couple of years old. I attempted to take it apart, managed to get the cover unscrewed at the bottom(it comes off as one piece) but because of the way its put together you can't actually take it off (lame). Anyway, I shone a flashlight in there, theres hardly any dust or anything that would be causing issues with the fan and when the chiller does actually run I can hear the fan going.

Any suggestions???
