On a previous post I emntioned my fridge was was cool and freezer was not cold enough to freeze all fans are working, damper working, evap coils frosted with just a little more build up in the middle,defrost heater working and a new defrost thermostat ,everything cleaned. but i noticed that the compressor seems only room temp to the touch but running also the lines coming out of it are only room temp,that don't seem right I thought one was supposed to be cold and compressor should be hot/warmer. could I just be low on freon or maybe something with the mother board,I would hate to pay a service tech for something I could do myself. HELP:(
