Scott W Oak Ridge , TN June 21, 2022 Appliance: Model KITCHEN AIDE Freezer cold; fridge warm (50 degrees). I installed a new air diffuser. I ordered it on Friday afternoon and it arrived the next morning. It took only a few minutes to install. My fridge is now holding at 34 degrees. This helped me avoid buying a new $2,000 fridge.
