Refrigerator Evaporator Fan is not Running

Hi,
I have below problem in my Refrigerator:

Compressor Running
Condenser Fan is Running
Evaporator Fan is not running.

I tested Evaporator fan by disconnecting and connecting with 120V and fan is working fine.

What could be the issue ?. What else I can check ?

Freezer and Freeze both are warm and not getting cold at all. While I was at Evaporator Fan, I checked Evaporator coil and it was hardly cold (May be 50 Degree F)

What could be the issue ?

Possible board under front kick plate bad, but is that available new has to be rebuilt. https://circuitboardmedics.com/12050506-defrost-control-board-repair/

Do you think it is in defrost mode and staying in Defrost mode ? If yes, how can I test it is indeed board and nothing else ?

How about refrigerator is low in Freon Gas ?

Looks like I have closed system issue. Leaking Freon. Not worth trying to fix it. Going to buy new one.

Thank you for everyone help here…This Forum is great.
