kitchen aid model KBLS36FMX01.
the unit will not keep a steady temp. in the freezer or fresh food. I changed the evaporator motor because it was faulty but it has been going nuts with temp variations in both compartments and the user interface has a mind of it's own with the display cutting on and off. I know it turns off if the door is open too long. it seems to have good air flow and the baffle motor appears to be alright. I don't hear the evaporator motor changing speeds as needed. I have been told that the brain is not available. It has to be sent off to be repaired. Has anybody run into this problem?
