My LG LFX25991ST freezer was not cooling. There are 2 evaporator fans, one of which, the middle one, is not working. I replaced this fan and it is still not running. Does this fan only run at certain times? I open the bottom freezer door and hold the switch. I never see the fan spinning.
See if LG’s support page for your refrigerator offers any help. Here’s a link to it: LFX25991ST
