Refridgerator Problems- 1993 Dometic s1621 not cold

We had a 94 and the fridge was dead when we bought it. I lucked out and the rv parts house had taken 1 from an auction and sold it to me for $350. I think it's almost not worth it to get an old one fixed. The old ones are fussy and have to be perfectly level to run right. Watch Craigslist, I see them all the time in our area. Good luck!
