We are having an issue with a Kenmore SXS refrigerator MN: 253.54629406 that keeps defrosting up. At first when we came out there we found it frosted up. The heaters and bi metal were working so we replaced the ADC board and forced into to defrost and heaters came on. Customer called back one week later and said same problem. We went back out there and thought the board we replaced the new ADC board, because we could not force it into defrost plus cold control, wiring assembly and dampener control and bi metal.Customer called back and is saying refrigerator works fine for a week then freezers up(same issue) Any help would be appreciated. Thank you.

Thank you for your question. On this particular unit you have replace what I would have replaced. Since that didn’t fix the problem I am wondering if you have frost anywhere else in the freezer? Is the frost on the evaporator over the whole thing like a typical defrost issue? Is the frost just on the top or bottom of the evaporator? Is the fresh food section colling properly? I ask those questions because if your evaporator fan is not running you could have frost build up on the top of the evaporator. If the air return is freezing over the bottom of the evaporator could be getting frosted over. If there is frost on the food in the freezer or ice building up in the freezer section you could have an air leak from the door seal and or the ice dispenser. Also, does it possibly look like a sealed system failure? Do you have a partial frost pattern on the evaporator? Is there an ice ball at the top? Also is the unit running for at least 24 hrs prior to arrival? Also has the unit been tipped on its side? Please, if you can let me know what you find.
