freezer/refrigerator too warm not ice build up. Low refrigerant usually results in cooling problems e.g. Is the compressor running continually trying to cool the fridge down? Do not be confused by the model number of the refrigerator at the top of the pages as the manual is also for your model. The error code list and meanings are on the next page in the service manual. Just to eliminate any other problems that may be causing/contributing to what is happening, try running the Self-diagnostic function during normal operation and check for any error codes. Some fridges have had anywhere from service bulletins to class action lawsuits about this issue. IFixit Staff Suggestion: View the freezer ice building up wiki for other tips regarding evaporator frost buildup. Replace the sensor, it is a cheap attempt (DA32-10104N) before going to the control (DA94-02679D), i am not 100% sure but i want to say they had to increase the defrost times and there is not a way to do that yourself but have to have a new board with the new programing. I would do this before replacing assembly as its the least likely and pretty pricey part. Honestly, these fridges are finicky and i have fixed this issue by just replacing the back panel as an assembly (DA97-12608A) If it were door gaskets you would have condensation on the walls and shelves before it made it to the evaporator. Your heater is fine, no ice near it and the hi limit is attached so we know it is good as well. Judging from the picture it would seem like either the defrost is not long enough or the temp sensor is out of spec. The fridge works fine otherwise…some freezing of the upper ice maker a few times a year…but general cooling is working…so I’m hopeful that there’s a simple MacGyver fix here that will keep me from clearing the contents of the fridge and defrosting every 4-6 weeks in the summer months. Something is happening to quickly accumulate ice in the upper portion…assuming it’s a leak of sorts? The noise is starting to brew again today, so this week I will be back into the fridge for a defrost…any recommendations for a more permanent solve? Thoughts on a copper wire wrapped around the heating element and extended to the upper portion to conduct some heat up there to avoid the ice build up? Sorry if this is a naïve question, but is low freon a potential issue here? If so, how to diagnose and/or recharge? As you can see from the attached picture, the bottom portion seems just fine, so it’s not the drain jamming up, for which I’ve seen some parts that can be bought to conduct more heat to the drain hole. We live in Wisconsin, and during the dry winter months I seem to get more longevity out of the fix…but when the humidity rises in the summer we are now opening up the back panel every 4-6 weeks to defrost the ice build up with a steamer.Ībout a year ago we had a Samsung tech out to our home and he replaced the heating element that runs along the sides/bottom…parts and labor ~$200. Fan noise is our first clue to the ice build up, and with a lot of online research I’ve learned how to remove the shelves, pull the back panel, and defrost the ice build up on my own…often in less than an an hour. We have a Samsung french-door, twin cooling refrigerator (RF28HDEDT model) that has ice build up in the back wall of the refrigerator.
