Hi all! This month, we’ve got questions on various RV appliances. Remember to send your RVing questions to This email address is being protected from spambots. You need JavaScript enabled to view it..
Hi Mark,
We’ve noticed an increase of icing on our fridge-cooling fins. It is the original Norcold fridge in our 1996 Itasca Sunrise. Food remains cold at a midrange setting and the freezer seems to keep things frozen sufficiently, so there is nothing to complain about other than a concern about the icing. We do clean out the fridge and freezer routinely. The icing is occurring while we’re hooked up to shore power and doesn’t seem to be any different whether it is set for normal operation or high humidity. We only run on gas infrequently. Wondering if there is something we should be doing differently.
Thanks,
Phil
Hi Phil,
Usually, when an RV refrigerator starts forming more frost but still cools normally, I’d look at the door gasket. It doesn’t take much of a leak to let humid, warm air into the fridge and that will definitely increase frost production.

Visually inspect the door seal for any tears or obvious problems. Clean both surfaces. Now, close the door with a dollar bill inserted between the door seal and the body of the refrigerator. You should be able to pull it out with some resistance, but in areas where the seal is not making, it will be very easy to pull out or entirely loose. Usually, there’s no way to fix a door seal, you just have to replace it. It’s not a very hard job to do.
