Dear AppliancePartsPros,

It started off with my refrigerator getting warmer and warmer. Contacted a local repair man and he diagnosed it over the phone(the best he could without charging me). He thought it was the thermostat in the fridge. Replaced it and still the same problem. Had him come to my house because now the freezer was starting to get warm and the fridge was not cooling. He now diagnosed it as the diffuser. Replaced it and the fan started running in the freezer. This is connected to the diffuser. Now the freezer is nice and cold again but the refrigerator is still warm. The temp started out at 60 degrees and it dropped to 50 degrees but it won't get any colder. What is wrong? Did I screw something up when I put it back together? I also can't feel any cold air coming out of the diffuser. I need help!!
