I am guessing you mean the "new" mini. I don't own one, but service a few. The pumps fail due to the low rent cooling fan employed. Check that the fan is free of debris on a regular basis. It is my understanding that some folks are plumbing in a small cooler and losing the fan completely. I have not tried this yet, but it is on my list. Use the correct fluid..... and yes, they fail with annoying regularity.
