Norcold fridge

[Zeroprotocol]

Recently bought a new trailer and it has a Norcold NR03IHM fridge in it. Everything works as it should except I’ve noticed the freezer gets frost build up on the top of the freezer near the door. I figure the door needs to be adjusted and I can’t see any way to do this. I’ve currently got it set to cold level 3 of 5. Do you think switching to level 2 might help?

I’ve check the manual and it says frost build up is normal but it doesn’t give any temperature ranges for the 1-5 settings.

Sorry it’s an N8XLT fridge.

My suggestion would be to put a thermometer in the fridge and one in the freezer. Then you will see what it's doing and you can adjust accordingly.
