After a bad experience with Sears service on a dryer (the timer broke for a second time a month out of warranty and they flipped me off), I turned to doing my own repair work when possible and so far have been successful. After delivery of this new fridge (10653606201 S/N SM38275XX.) (I left out the last two digits for security), in my new house, I realized the plumber left out a bridge connection under the sink for an icemaker or the outdoor faucet. (I am on a slab...no room for stupid errors) I carefully replumbed my cold water side to take care of the problems myself. After all the hookups with the heavy duty hoses, the icemaker would not function properly. Sears put in a new control board and icemaker parts and everything was fine for about two years. Two weeks ago, I needed a lot of ice for two large coolers for meat and produce transport to a remote cabin. I used the rapid ice cycle. No problem there, about what seemed 20 to 30 pounds of ice in a couple of days. Wife called the cabin the next day and said that the fridge side was 58 degrees. When I got home the left upper vent was not producing air flow. Went thru several two or three hour power off cycles and the air flow would work for about 30 minutes and quit. Freezer was fine with air flow and icemaking and holding at zero degrees. The return vent seemed to be working, although barely able to hold a kleenex. (DO NOT KNOW IF THAT IS NORMAL) Repairclinic.com diagnosed the diffuser as the culprit, but out of stock and having to wait two weeks. Diagnosis sounded logical, however. If my research is correct the diffuser works with the electronic thermostat to open and close the diffuser vent to more closely regulate temperature (than a manual vent control) i.e. opening the door a lot, or not much at all. I do hear a winding up whirring type sound, as though a motor is trying to open the louvers and it recycles itself a lot, seemingly in failure, probably in my guess from either or both a component failure and freezing from the diffuser unit. This is information I only collected today, which seems to reinforce the initial diagnosis. It seems as though the control panel is OK but considering the wait time on components, I thought it in my best interest to post here for any additional opinions. To settle the household down a bit, yesterday I put a stick type pen in the louver so that we could use the fridge. Of course even with minimal air flow, this morning it was below freezing, until the door was opened several times. That is where I surmized that there is a scalable air flow linked to the control board thermostat and the diffuser interacting. Hopefully I have supplied enough information to the helpful moderators here to get additional opinions. So, right, wrong, or doing something stupid, have no problem with responses, but nevertheless, please respond.
