I have a kitchen aid fridge that is just over 5 years old that kept freezing up and stopping the fan.
Lea appliance repair came and thawed out the fridge, charged $200 to do that, and it didn't help. They came and replaced the computer board, $600, didn't help. They ordered a temperature sensor, that they said is on back order. I have been waiting 5 months for it, having to thaw out my fridge on a weekly basis. I have tried calling Lea many times and they have only picked up once to tell me the part is still on backorder. My husband just looked up the part and it is a available online from Sears. $59. Unfortunately I just ordered a new fridge that is being delivered on Thursday. I guess we will have 2 now.
