Lower dish rack: Two racks are listed. What is the difference? Both say they can be used on the above GE dishwasher model. Your part numbers are AP2040277 and AP2040288.
Answer Hello Gene! Unfortunately, we do not have the information available to tell the exact difference of the two racks listed. After further researching your model with GE, the correct lower rack is part number WD28X10284. Thanks.
