With some help from my brother over the phone I figured out that the condenser fan motor was bad so the system was over heating and shutting down. I found Appliance Parts Pros online, found the part I needed right away but then called to ask about their return policy, just in case the new fan motor didn't fix the problem. Needless to say, I was very impressed so I ordered the part on a Sunday evening and it was delivered on Wednesday. I had the new motor installed the same evening I received the part and the fridge is working like new again. A friend told me of a local store that would have the motor I needed and I wouldn't have to wait. I looked the part up online and found that the part, plus sales tax, was $60 more expensive than the cost of the part from Appliance Parts Pros, including shipping. It was worth waiting two days.
