Hi,

What fan is it? The refrigerator fan motor? Or freezer fan motor?

Here's the service manual: https://www.dropbox.com/s/9o69um9xpjx9z8i/LMXS30776S.pdf?dl=0

Refrigerator fan testing is on page 50
Freezer fan testing is on page 52

Here's the refrigerator fan motor for your model:

Here's the freezer fan motor for your model:
EAU61524007 Motor,dc


Here's the control board for your model: EBR78643401

Let us know how it goes.

Both freezer and refrigerator fans not running but if I push the reset it will work for 2 minutes, it's only and I changed the control board and still not running

I'm not Sure if the door switches control the fans or not or any other sensors control the fan I really confuse

The only thing you can do now is get a multimeter and start volt testing the fans per the service manual.

Or have LG come out and do it for you.
