The freezer was frosting, but nothing in the refrigerator section. I shut it off and tried again with the same results. I then disconnected the generator and plugged the extension cord back in and the refrigerator worked perfect. Could there be an issue with the generator?
Hi John and Kim, I doubt there's anything that could be wrong with the generator that causes partial operation of the refrigerator. But it's possible that the generator might have been running, but no AC getting to the refrigerator - a breaker tripped, or a problem with the transfer switch that switches AC from shoreline to generator. In that case, the refrigerator might have been running on 12V. Of course, if your battery is ok and propane was on, it should be cooling but the 12V/Propane side of the refrig could have a problem that you've not noticed if you usually run on AC.
When you were testing, did you allow enough time for the refrigerator to get cold? On a hot day, it may take quite a few hours before the refrigerator compartment starts to feel cold, although the freezer compartment usually gets cold pretty quickly.
Another possibility is an air leak to the refrigerator compartment. If the door were not completely closed, the freezer would get cold but the refrigerator would stay warm. If after you checked it, you closed the door completely, that would also explain why it started cooling.
