Kitchen Aid Refrigerator Issue

Hello everyone, i have a Kitchen Aid model KSF26C4XYW03 refrigerator that twice in the last 2 weeks has stopped running. I called Kitchen Aid the first time and they said all I have to do is reset it by disconnecting the power for several minutes and then re-connecting. This does fix the problem, but since this has done it twice within 2 weeks there must be an underlying cause. Would anyone have an idea as to what is actually causing the unit to stop working until being reset?

Thanks in advance for any help,
