Attention Avanti Thermo Electric Cooler Owners!

The search function has been my enemy here recently and I can't seem to find any information relating to any necessary modifications to these units in order to make them cooleradors. I'm having some wild humidity fluctuations and the door is rarely opened.

Here's the specs:

It's a 16 bottle thermoelectric

It has an internal fan that is always on, but from the parts diagram above, it doesn't look like it has any direct air flow from the outside
I have 1lb of heartfelt 65% beads that are pretty thoroughly soaked
I have new batteries in a freshly calibrated hygrometer

Any thoughts on this model? I read at least a dozen posts on this and the former CS where people claim to have no problems at all with the unit. What could I be doing wrong?

Thanks for any help you can provide!
