Hello,

I'm looking for some direction or help with my KitchenAid side by side. There is a rattle about every 15-20 minutes lasting about 15 seconds each time, coming from the inside upper portion of the refrigerator. After some trial and error in service mode, I am able to replicate the noise when I activate service test 121, which the tech sheet attributes to "Damper Operation". A few hours searching the internet later, I cannot find any part or video that speaks to the damper operation or this service test code.

I'm above average handy and looking to tackle the job myself, preferably with the help of YouTube, but I can't figure out where to start. Can someone help me with this elusive "Damper Operation" error?

Thanks much

Air damper control opens and closes to let air into the fresh food compartment. Probably a stripped gear tooth causing the noise. To access it remove the air cover insert/grill (release the 3 tabs and it pops out). Remove the two mounting screws in the air cover:
