we have a DN 501 E.  we had an AC guy come out and say there was no leak and added freon for us.  it was cooling nicely after that.  It is now no longer cooling again.  can't find any service people or companies out here so we are at a loss.  Idk if it needs a new compressor, refrig deck, or what!!! It's located at a pool where we live and we have been losing all those sales, very sad!

     i have a dixie narco 501E and recently found out it is not cooling.  i hear the compressor going and i can feel a cool "wind" from the bottom of the refrigeration deck, but sodas won't cool.  it did freeze over once before last year but worked ok after that.  i don't know how long it's been like this because it's in our mobile home park and the pool is only open during the summer months and that's where it is.  any idea what it could be?  every tech i call local wants to charge just to come out and look at it.  I just need to know where to start.
