While you think the fan solved your problem, it does not. Your Norcold has a built in defrost timer system that shuts the refer OFF every 49 hours until the Temp Thermister reaches 39 degrees. Then it comes back on. This shut down allows the ice/frost build up to slowly melt and drain out the back to the rear drain pan. Your fan helps speed up this process. Doug
Well, my fins used to frost up, and since having the clip-on fan, they don't any more, so I consider the problem of fins frosting up solved.
