Harold, I'm sorry you are having this problem with the refrigerator. Unfortunately, the model listed is not showing to be a valid model number. However, if the freezer is not cooling, the first thing to check will be to, see if the compressor is running. If the compressor is running and if there is no frost on the back wall in the freezer, it would indicate a problem in the sealed system or with the compressor itself. If the compressor is not running, it could still be a problem with the compressor but it could also be with the starting device on the compressor or the cold control. Now, one other possibility will be if this model has a fan motor next to the compressor. If there is a motor there and if it does not run, it will cause the compressor to overheat and stop running and the unit will stop cooling. In this case, the motor will need to be replaced. A technician will need to make the checks for the compressor and sealed system, if the problem leans in that direction. You can call 1-800-469-4663 to schedule a tech to come out. I hope this will help you.
