This air handler was complicated to install. The directions refer to parts and pieces that are not identified in the diagrams so unless you have an extensive knowledge of refrigerators, it's hard to follow. The pieces did not fit together well either. It took me several hours to install and when all was said and done, the original problem was not fixed. I'm having a refrigerator repair company come fix it next week. Additionally, I ordered this item due to a recall on the current fridge I own but I still had to pay for the part and labor was not included. I guess recalls for Sears are different than how car companies handle recalls, covering all costs. At one point I tried calling Sears for assistance and they wanted to charge me $50 to talk on the phone about a part of the directions that was confusing. Overall I was very dissatisfied with the product and the customer service. I will certainly keep this experience in mind when we get a new fridge.
