Freezer frosting up?

Frost is caused by excessive humidity in the air. When you open and close the freezer, this air enters the freezer and the moisture condenses on the freezer wall as frost. The only real way to minimize it is to run a dehumidifier in the FW.

That's a good thing it's working. Most of these devises are not frost free like your home refrigerator. I have to defrost mine about every 3-4 weeks depending on build up. The more you open the door and how humid it is all contribute to how often you need to defrost.
I have several insulated bags that I put the cold/frozen stuff in so I can get it defrosted as quickly as possible with out it melting. I like to use a fan on a stool to speed up the defrosting.

Casinojunkie,I have been fighting this problem for years, even with different RVs. My current RV is a 2012 and i bought it new. I have put posts on this forum and followed all the advice, but still have the problem. My gaskets are new, I try to minimize the length of time I have the doors are open-I think i have tried everything. I will follow this thread in case there is something new. Good luck.

Derh20 mentioned gaskets. Check yours. Also check the tilt -- fridge feet should be adjusted so that, when you almost-close the door, it closes itself that last inch or so.

When my fridge frosts up prematurely it's always because it was open a crack overnight. For example, something got caught in the door seal and it didn't close tightly, or the fridge (or RV) was not at the proper angle. A 'dented' seal could do this, too.

What others have said about the gaskets. We purchased our trailer in 07 and noticed a lot of frost in the freezer. NorCold reefer, upper freezer. The gaskets were all okay but I noticed a type of thick white plastic tape? on the corners of the freezer compartment, opposite the hinge side. This plastic tape was covering small holes used when the door hinges would be reversed to have the door open the other way. I removed the thick tape and used a very thin tape to cover the holes and the frosting problem went away. It takes very little to break the seal and have air leakage causing frosting. Hope this helps, good luck.

I agree with the gasket and other leaks around the door, as others have suggested. You should check for other leaks as well. I had a ridg/freezer that had leaks in the rear of the cabinet. To check for such leaks, remove the outside cover, to allow sunlight in the rear of the cabinet. Stand in front of the cabinet with the door open, and drape something over yourself to block light. (I used a black garbage bag.) Look for light. If you find any, seal them. good luck.

To solve the fins from getting full of ice within two weeks, what we do now , we run the frig a bit "less cold",and now every thing seems perfect this is a Nordcold 821 Ronald.

You can check the door gaskets with a dollar bill to see how easy it slips through. I had one area where it did not seal well. I removed the black latch on the refer itself not the door and removed about .060 of the back and re installed, this tightened the door seal. In addition to the gasket there is a drain tube out of the back into an evaporator pan, sometimes these crack of the plug on the end is missing and can let humidity into the refer which cause frost build up.

Lots of great reply's but after you have checked the gasket for air leaks you are still dealing with a old style refrigerator that does not automatically defrost. You have to manually defrost it. How often has a few variables like how often do you open the door how high the humidity is. I defrost mine about every 3-4 weeks depending on conditions.
