I have this appliance, manufactured in 06-05. A loud fan (or motor) type of noise cycles on and off, but not on any type of regular schedule. It can get quite loud, sounding like it is struggling to work. Also, when I open the refrigerator door, the front of the wall that separates it from the freezer can be pretty warm to the touch. I am curious if that is normal, as I haven't noticed it until recently. Also, do you have a recommendation for that motor/fan sounding part? Is this a sign that I should just plan to replace the whole appliance soon?

I got great advice (and the parts) from you guys when the ice maker broke a few years ago, so thanks for that!
