Usually,I try to cool the frige a day ahead of time when we go camping. I run an extension cord out to the trailer ( 2001 Eagle 14 SO ) I did realize that the battery needs to be connected in order for it to work this way. Lately, even with the battery connected, the frige isn't working when switched to 120V. When I open the door to the frige controls, it is warm in there like something is running but the frige isn't cold. It does work on propane. I haven't tried pre cooling on 12V DC. There are 2 fuses by the frige controls, I checked them visually and they look good. What am I missing ? I did clean the connections on the battery to correct a previous not charging issue. It has worked previously on 120V. Is there another fuse/ ckt breaker ?
Appreciate any help.
