I have a GE refrigerator (model GTE21GSHBSS). For a few months, there is an occasional rattling in the back of the fridge. I don't think anything is loose as I checked the screws/drain pan, so I'm wondering if it is the compressor. I had an appliance repair person out but they couldn't figure it out as it wasn't making the noise when they were here.
A video of the rattling is here: https://files.fm/u/wpgwf6peu#/view/3vjk3grp8
If anyone can let me know the next course of action, it would be appreciated.
