OK thanks guys I have changed the board to the Dinosaur from PPL. Now the controls all work , stays on ac, but the refer. doesn,t cool. been on for 24 hours, the a/c element is hot but no cooling. How do I test the thermister. Dinosaur says that if the thermister tests then I might need a thermister adjuster.
Thnaks for the tip on thr $89 deal.

You do NOT test the Thermister. You wire the 120 element DIRECT to 120 power for 24 hours. IF the refer does NOT get below 40 degrees and below 10 degrees in the freezer, your Cooling Unit is bad. Doug
Great advise again from Doug I might ad that you should check the freezer part vs the fresh food area. When mine acted up I had great cooling in the freezer and not much in the fresh food. As doug suggests you need to direct wire the element to 120 and see if it cools. When I had my trouble same refer as you I called dinosaur direct he sold me the board and another part I forget the name and then he walked me through the adjustments on the other part I just can't remember all the details as it has been a couple of years.
