Buggy program in Dometic Air conditioner

Well Engineer or PC guy. BOTH have the same problem in logic as it relates to RV's. The control board is NOT a "computer". There is NO programmable logic aftermarket. I read you first post about AC problems. You are trying to use your knowledge on RV components. Apples and oranges. Now, the Freeze thermistor does NOT--NOT allow the evap to freeze up. It STOPS the ice from forming BEFORE it causes a air flow restriction. Once the Thermister senses the freezing temps on the tubes of the evap it shuts off the Compressor. It should NOT stop the Fan IF the set temp has been reached and on AUTO. If the Fan is on Hi or Lo, then fan will run regardless of what the wall tstat does or the Freeze Thermister does. THIS is why the Upper control board would be at fault if the fan cuts off when on AUTO/COOL and the fan shuts off when the Compressor shuts off AND THE SET TEMP HAS NOT BEEN REACHED. Are you positive that the set temp has not been reached and the compressor and fan are shutting off because the AC has cooled and done its job? Doug
