The lady told me her cousin was an electrician and tried to fix it,
Someone relative is always a electrician or better yet a engineer.
I had to fix a refrigerator one time for a guy that was a retired engineer.
When I got there he had some theory as to why it was not cooling correctly.
I don't remember just what his theory was, but he was wrong.
The evaporator fan stopped running and needed to be replaced.
So then he had to make it more complicated then it was and try to figure out why the fan had quit working and such, lol...
Just let me replace the motor and move on. After all the refrigerator is like 20 years old. You can think about why the motor quit after I leave.
When I left he was still examining the old fan motor trying to figure out why it no longer worked.
