Dometic Fridge issue

[vicn2000]

I bought my 1986 Excella in Oct and put it in storage. The owner before me had recently installed a new fridge and it worked fine when I bought it. I put my trailer in storage and just pulled it out for the road....but now my fridge wont get cold. The lights come on on the control panel.....but that's it. Since this is my first Airstream I'm hoping it's something simple to fix.
Does anybody have any ideas? I'm tired of drinking hot beer

If the lights come on, you are getting 12 volts. The only thing I could think of would be the module card. Are you leaving it on overnight ? Is it a two-way or three way. Will it run on propane?
