Yeah, maybe I have a dud refrigerator?

The current when running, even with the rear jumper thing set to "low current" position, is definitely greater than 2.5A. And it does not exhibit the high startup current that you observe. It's steady as can be.

I did contact the distributor when I initially hooked it up and he said to set it to the low current mode. Followup questions were ignored. The manufacturer did not respond when I wrote them for clarification and opinion.
