Could also be a bad switch. VERY easy to test and/or replace that side fan if bad (search Noisy Norcold for pics). It's a standard cooling fan used in computers (12v I believe). (View Post)
I think you're correct Scott about the exterior (aux) fan on the side grill. I'm guessing one of the three glass fuses protects the stock fan under the coils on the frig itself. (View Post)
Check out "Fuses for Newbies for the location of the fuses on the Norcold. Not sure which of the three protects the fan on the Norcold itself. (View Post)
Thanks Michelle, but I got the idea from Tony on this forum. BTW, make sure you put some tape on the door and T@B where the drill chuck might rub against it. (View Post)
