LG French door LFC21770ST Freezer cold/fridge warm
« on: September 29, 2021, 10:06:48 PM »

Unit is 13 years old. Freezer is cooling great but fridge is warm. Took a chance and ordered a replacement motor for the evap fan (seems to be a common source of failure). Watched a few videos on replacement and I have a stupid question. In this model am I looking for the fan in the back of the refrigerator or the freezer? I've seen both.


I've spent the last week digging up irrigation valves to fix a leak, so probably the freezer. My knees are done.

Located in freezer and replaced. Removed refrigerator interior panel to check for any blockage. Ran self tests - no codes.

Compressor fan works during self tests, but runs sporadically during regular operation. Replace compressor fan or something else?

I don't have time to look at this, but this may help you out some if you don't have it.
