I have a 12 year old Maytag refrigerator freezer. Any food that sits in the freezer for too long takes on a stale odor so I decided to clean the freezer per the manufacturer's instructions.
When I turned the freezer back on, there was the smell immediately. It's coming directly from the fan that blows into the freezer. It doesn't appear that this duct area comes apart without a lot of disassembly. The screw comes out but the plastic housing is affixed to the bottom of the freezer. Even if I did clean it, I don't think the smell is coming from that area alone.
I did clean the defrost pan below the refrigerator but that didn't make a difference.
Can anyone suggest where to look for the root of the problem?
Thanks
