Jennifer T Athens , OH August 08, 2018 Fridge warm but freezer still working well. We decided to replace both the thermostat and the timer but I believe the problem was the thermostat. The frost was not exactly obvious until we began to take the unit apart. The repair was quick and easy. It took longer than I would have liked for the fridge to turn back on after the repair so be aware of that and don't worry. Our fridge was a little different than the one in the video but everything went well and the video explained it all. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
