Fridge Fan is loud

I have a 2012 xlr 35x12 and when the refridge fan kicks on, it seems to have a pretty loud whine. Is that normal?

Seems to be a problem. As a tech, I go to the local computer store and buy a 12 volt computer cooling fan, less than $20, and replace them. Customer service rather than wait on factory to ship another junk one.

Loud Fan Solution

Like others, I couldn't live with the cheap muffin fan on the back of the Dometic DM2652 in my Sunseeker cycling on and off. I sourced a couple of 120mm computer 12V fans with built-in thermostatic control from my local computer store (Gelid Silent 12 TC). These fans are bigger than the original 90mm fan and run at a variable speed depending on temp (from 750RPM at 22C to 1500RPM at 42C).

After pulling the fridge, I removed the single 80mm fan and the thermal switch that was clipped to the heat exchanger tube. Just for fun I hooked the new and old fans up to a 12V battery. The new fans were virtually inaudible compared to the original!

I used 4 small angle brackets, screws and a bit of construction adhesive to attach the new fans to the back of the fridge. I also attached the thermal sensors for the fans to the same spot that the original sensor was (pics 1 & 2). Power is still supplied via the same red wire with the inline fuse but I added a shutoff switch in case I really need to conserve power (pic 3).

Now instead of the noisy fan cycling on and off at about a 1 minute interval keeping me awake at night, I have the continuous, but much quieter hum of the 2 variable speed fans. Added bonus, the fridge runs colder than before as well!

Hope this helps others get a better night sleep.
