Well I just came from a living nightmare.....Kenmore bottom mount, french doors...Utah board....lots of ice...when I say lots of ice, I mean lots of ice, 4 inches or more thick covering the freezer baskets and evap. Freezer doors have been left open on many occasions. But at first I thought defrost problem...could not put that #*#$& utah board into diagnostic mode...I danced with those keys for seemingly hours....I hate those things....so instead, I steamed and steamed ...ice cream, yogurt, fruit and vegetables lodged in the ice like fossils from a different era. Crap is everywhere....finally get to the evap cover....removed it lots of frost and ice...ice was very thick, especially around the fan and top of evap. Then all of a sudden, the fridge cut off and the heater turned on. Eureka! Defrost not a problem, it was caused by ambient air and the rime ice blocked defrost drainage causing clear ice to form.
So I started steaming, and using hot water....by now I'm covered with vanilla Ice cream, bean juice and water. Finally finished.steaming...I mean finally as in I seriously just got home right before posting this message. But before I left, I like to check temps just in case there is another issue....Temps dropped rapidly until it got around 29 degrees. Then it wouldn't budge....took back panel off again and top two lines heavily frosted...others..nothing. Maybe I didn't give it enough time...put cover back on, closed door, waited another 20 minutes....same.thing. By now I'm so tired and hungry I contemplated eating the vanilla ice cream coating my shirt and licking the bean juice off my pants. On top of it, this was some sort of group home or something, and everybody left....so did I.
