Fridge started making a loud whirring noise, seeming coming from the ice maker area. Sounds like a high speed, motor or compressor sound.
Noise stops when opening the doors
I defrosted and turned down water pressure with no success.
I check the auger fan assembly. Fan is free spinning with no interference. I also tested the ice maker and dissembled it to check the 12v motor and condition of the gearing. There appears to be no wear. It tested quietly.
The fact the noise goes away when I open the doors has me thinking it could be narrowed down further. Any ideas?
