We have a KRFF305ESS00 Kitchenaid refrigerator. This 25 cu ft unit has a refrigerator compartment with french doors over a top-loading freezer pull-out bin. It is 4 years old. No ice maker or water line.

Periodically there is a two-times-per-second knocking sound that runs for 10 seconds to a minute. It will abruptly start and stop. The noise is not related to the expected quiet hum of normal fridge cycling.

The attachment is a recording of the noise.

Do you have any idea what this might be? We live in a remote location and it is hard to get service.

If it’s a simple replacement, I’d be willing to try it myself.

I heard it, is the noise coming from inside the refrigerator section? If so, that sounds like possibly the air damper is the culprit.

Here's the air damper assembly for your model:
