Compressor on - fan stops after 5 minutes

Hi and thanks for visiting my post - I have a Kenmore Super High Efficiency 9000 unit and the cooling fan stops after about 5 minutes. I pulled the capacitor and headed down to the local electric supply house and was told it is ok. The consensus was that it needed a new relay switch which I installed and after 5 minutes the fan quit again. Just to be sure, I exchanged a capacitor from another unit and no change. The fan motor seems to spin freely and does not get hot. I can swap it for the fan on the other unit but I think it has to be something else.

Any diagnostic ideas would be greatly appreciated.

Thank you,
Peter

What is the power reading at the fan terminal after the fan stops?

most likely the fan motor, if you really have an identical unit I would swap out the fan motor to do a 100% test. Might not want to put this one in the other unit until you see what this one does though might save you some time. On a average day I can typically swap out a condensor fan blower motor in 22.8 minutes if there are no overgrown sticky holly bushes around it.......
