Do the dollar bill test (bill between seals/frame door closed and pull it out---should be tight/have resistance
Do it in Several places


Clean seals/frame so you get good clean contact between the two

IF seals are not making good contact you can 'reset' them:
Place cottonball under seal in each corner
Then WARM entire seal using hair-driers (do not overheat but need to get the whole seal warm)

Then close door and let the warm seals cool///resetting them

If seals are good...dollar bill test then it could just be the warm humid air replacing the cool air when you open fridge doors---especially if you lookie-lou


Model of fridge??????????????


Is it time for your medication or mine?

LOL.... I'm not a youngster, 63 years old here. However, this is my first RV. Thanks for the info.


Ah but to me 63 IS a youngster.. I remember Fridges you had to defrost.
And RV fridges... You still do.

On one thing that will cut down on the frost in the freezer.

KILL or Rip out the ice maker and use a countertop (Portable).. I did.

More ice (up to 26 pounds a day) and less moisture in the freezer due to that "Warm (more than 32 degrees) water thing I mentioned.

And when the counter top unit went compressor up.. All I needed to fix it was a browser.. a phone, a car, a plastic retangle (Credit/debit card) and a knife (to cut the tape on the box).

You need all those for the Built in ice maker too but TOOLS. lots of TOOLS and you may need to remove the fridge to replace one part.


Home is where I park it.

To: wa8xym - I remember my mom defrosting the freezer when I was growing up. She set up a small fan in the door and would scrap the frost and ice out.

No ice maker in the freezer in my RV.

Good lord. Everyone over 40 remembers defrosting their freezer.

I'm not QUITE that old. but... My mother tells me that her father made one of the first Refrigerators in California.

He was a refrigeration engineer workign on the big Fishing processing boats (They moved the fish processing onto boats back than so the fleets could catch more fish not having to return to port to offload)

He converted an ice box to a Fridge.

Alas I never met him. he died just weeks before I was born.
I do recall Grandma however.

I have a Norcold 1200 4 dr and I just shut it off, put the food in the big cooler and it defrost and water runs out the tray to the outside. Only takes a couple of hours. I do have to soak water up off the freezer bottoms though. Good time to clean it. We added one of the small fans on the rt side fin area and it has helped a lot. That was the area where the ice started all the time.

Guess you have an older 1200 model....no 'defrost' cycle?
S/N 83170 and lower doesn't have that

S/N 83171 and higher has a 'frost' management power board.
Shuts down cooling cycle every 40-48 hrs
When Food Compartment fin temp reaches roughly 32*F (41-42*F Air temp) the frost management restarts cooling cycle

Freeze temp plate will reach rough;y 22*F...so food stays frozen/no defrosting in freezer

Ah you youngsters.
Yes it is normal
Modern RESIDENTIAL refrigerators have heaters in them (Defrost elements) so first they cool then they heat.. That way you don't need to defrost so often

RV units don't have the BTU's to spare so they just cool and like Refrigerators of old when you open the door and warm air rushes in...

or when the ice maker (Which by the way may have a heater built in) cycles and warm water rushes in.. Frost forms on the cooling plates.

What can reduce it

Well I had a 3 fan version of this.. Wish I'd have had a 4 fan but that's another item

Fridge fan

It mounts in front of the fins and did a fairly good job on the area it blew on. Thing is my fridge was wider than the assembly (Why I needed the 4th fan)


How do you wire this item? I’m having same issue of frosting
