Norcold 1200

I have a 2003 Fleetwood Southwind 36RS with the Norcold 1200LRIM refrigerator. Lately, I have started noticing a lot of condensation on the inside top of the fridge part but not the freezer part. Freezer is great and the fridge cools great as well, but the fins ice up quickly. I just replaced the thermistor but still icing up. I tried to add some thin stick-on seals to see if this would help the door seals work better. Just tried this so not sure if it is gonna work or not. I there an easy way to see if the unit is going into a defrost cycle? And any tips or help would be greatly appreciated. Again, the unit works great, just a bunch of water on the inside and the fins icing to the point that you cant even see them. Help!!

Here’s a thread of mine from 2009 ( my first year here ). It fixed this issue.

Sounds to me like a leaky door seal letting moist air inside. It ends up condensing on the cold surfaces, mostly the fins. Have you tried the dollar bill test? Close a fairly crisp $1 bill between door and frame and pull it out slowly, gauging the resistance to movement. If its pulls through without any drag, your door seals are no longer tight.

Hi there. Thanks for the reply. I did try the dollar test and there seems to be some resistance so i am not sure if the seals are bad or not. I have noticed that I do not hear the rear cooling fans cycling on and off, so this could be an issue as well. It cools great and the freezer is cold, but I have not actually checked the temp with a thermometer.

External fans are there to enhance airflow/draft to remove heat from absorber tubes and condenser fins.
Removal of that heat is necessary for freezer and food compartment to get COLD


Icing up of fins in food compartment is due to warm wet air coming in contact with the cold fins


Nothing to do with whether external fans are working or not
