Freezer frost buildup

[2toGO]

Our 2020 3121RL has a Samsung residential fridge that lately is creating a lot of frost in the freezer section. We use it 8-9 days at a time, FL locations most recently, it’s never full of frozen goods to block air flow, temp is set @ recommended -2F, freezer door gasket is clean and not damaged, just don’t understand why the sudden onset of frost buildups. Doesn’t seem to happen as much when in GA & TN. Anyone having same issue? Suggestions to resolve most welcome…THANKS!!

My first guess would be that something is going on with the automatic defrost system. Samsung may have a way to force a defrost cycle. I’d see if you can find details in manual on how that’s done.

I found the list of things to check below, and also a video on checking the defrost heater element.
Since you are seeing more ice build-up in FL - I would guess it has something to do with the freezer door weatherstriping. More humidity in Florida + leaky seals = more ice build-up. Press the EASY button - check and clean the weatherstriping first before moving to the other items. The video is interesting but you may not need to do this much work.

Much more humidity in FL than in GA and TN also.

I had a similar issue, likely that you’re pulling in outside/room air. Have you done the dollar test around the seal? It’s likely the door is not sealed at the top when closed. I actually used washers to shim the attach fittings to door to get a good seal. Mine works perfectly now, not sure whether the door gets bent or the slides get out on tolerance but shimming will do the trick.

Same thing happened to mine. Shimed the door and no more frost.
