I first watched U-Tube tutorials for an hour that addressed the defect and demonstrated the typical repair formats. There could be 4 separate components that required careful testing to determine which part had failed. I called GE service and they sent a technician to inspect my refrigerator and diagnose the problem and identify the defective component which was the evaporator fan motor. I watched the tech. take apart my freezer and saw the technique. That step cost $100.00.
The tech wanted to replace the motor but did not have the part on his truck. He advised me that he would return in 3 days with the motor and complete the repair. The labor cost to do the repair was $80.00 and the part cost was $57.60, after application of a 20% GE on-line discount coupon. I told the tech I would call GE if I wanted them to complete the repair.
I then went on-line to shop the part. I discovered that AppliancePartsPros.com was the least expensive at $43.00 for the part which included sales tax and shipping expense. I ordered the part in the morning from APP.com. The following afternoon the part was delivered to my home. I obtained one day delivery service as part of APP.com standard delivery schedule. The replacement motor seemed to be correct. I remembered how the GE Tech disassembled the inside back of my freezer to inspect the defective motor. I remembered the U-Tube tutorials on how to install a new motor. I was able to remove the defective motor and replace it with the part from APP.com. Once the work was completed my refrigerator operated correctly.
All of these appliance repairs require some mechanical skill and intuitive ability to analyze and comprehend how a component is situated, functions and connected within an appliance. Spend time and patience watching the various U-Tube tutorials describing how to repair a given defect. Making a correct and accurate problem or component diagnosis is about 85% of the task and will prevent expensive and time consuming guesses as to what part needs replacement. Remember, that you lack the training, experience and information that the manufacturers' technicians have when they arrive at your home to perform a needed repair.
