Our Carver 455 has the original refrigerator, which is still working after 22 years but may need replacement in the near future. Anyway, First Question: we are away from the docked boat (near Tarpon Springs, Fl) a couple of months at a time, and we are wondering if it is better for the refrigerator to leave it on, or turn it off, wipe it out and leave the doors open. We're worried that if it is off for a long period, it might do more harm than good, but we know nothing about this either way. Advice??? Second Question: how the hell would we get the old one out and the new one in? We have a fully enclosed bridge and aft deck with glass windows and solid sides, and the doors of the aft cabin are too small for a refrigerator to fit through. The only opening that appears big enough is the center windshield glass section. HELP!!!
