I have a new 5th W with a Dometic Refrigerator model DM2862LBFX that has a noisy fan. The loud humming noise starts after the refrigerator has been on for a while. When it cools off outside late at n...

Cheap sleeve bearing fans get noisy, and will do so faster if the impeller blades get caked with dust. Also a Horizontal running plane will cause sleeve bearing fans to wear faster.
Solution get a dual ball bearing fan of the same size, but fluid dynamic bearing fans can be quieter and more efficient.
Don't know what size? well neither do I, but likely 120MM. Pull the covers off, have a look. If you can get a pic of the fan and the top of it where the part numbers are, we can figure out what CFM rating it is and order a better replacement. Computer Muffin Fans vary greatly in noise made for amount of air moved and current consumed to do so. A variable speed fan is nice so one can turn it up just high enough to move the most air at the most tolerable volume.
Silverstone Fm121 if it is a 120MM fan. 33 to 110CFM. 0.09a to 0.4a, nearly silent to 39DB.
I fan like a Noctua NF-f12 moves 53 CFm for 0.05a and has a 6 year warranty.
Replacing it can be as easy as removing 4 screws, cutting two wires then resplicing them onto new fan and returning screws.
