Kenmore side by side refrigerator R134A

I bought a condo with a Kenmore side by side refrigerator in it - R134A. Although the fridge and freezer work well, since the day I moved in more than 1 year ago, a loud knocking noise comes from the back of the fridge with inconsisent regularity. It can be loud enough and for long enough (minutes) that it wakes me in the middle of the night; it can also occur during the day and can be for just a few seconds.

Any suggestions?

Hearing knocking noises on the back of your refrigerator can definitely be a bit spooky, and definitely needs to be fixed. I have taken some time to research your question here on the Manage My Life website and I noticed that someone else had asked a similar question with a posted response from an expert. I attached the link below for you to view. I hope the link that I provided is helpful.

I can understand your concern. The information you have received is correct. This is a normal noise that is associated with the 134A refrigerant. Sometimes adjusting the drier will help but I strongly recommend having a technician make this adjustment. It's very easy to kink or even break the tubing, while making this adjustment. If this were to occur, it will be a major repair. I'm listing a site you can access, to have a technician come out. Here is a link for the website:
