Dometic RM2310 - nothing, zip, zilch, nada

I bought this little 2-way refer a few months ago from a sailor. He'd only used it as a spare beverage fridge, unmounted, and via 110V. It was working swell when I bought it. Brought it home, placed in on my covered porch with a heavy rubber cover and let it sit. Sat outside through the winter - expecting to put in into the Silver Olive this spring.



I brough it inside today and plugged it in... nothing. (I'm not really prepared to hook it to LP - as the lnes in my AS were removed prior to my ownership.)



Sigh. A bad work day enhanced by this.... any suggestions?
