Even frost through the compartment points at air getting in; a solid build around the rear vents points at the defrost circuit. Check the door closes squarely and that nothing on a shelf is holding it fractionally open. Do not chip at ice around the vents. ### Why clearing the ice is not a repair People defrost the cabinet manually, it works for a few weeks, and it comes back. That is not a failure of the defrosting — it is confirmation of the diagnosis. Whatever put the ice there is still doing it, and on a column the second build is usually worse because the drain is now involved too. The useful thing to record is how long it took to return, because that number separates a door problem from a defrost problem better than anything anyone can see. The door is not sealing On a column carrying a trim panel the hinge has been taking that weight for years, and a door slightly out of square lets humid air in continuously. The defrost circuit is not completing Heater, cut-out or control. Ice grows on the evaporator until air stops passing it, and the cabinet then fails for a reason that looks unrelated. The drain has frozen and backed up Water that cannot leave refreezes where it stands, and on a column that is at the bottom of the evaporator where nobody sees it. Look at where the frost sits Even through the box, or concentrated at the vents. Two different repairs. Close the door and watch the seal A gap you can see at one corner is the whole explanation. Note how quickly it comes back after clearing Days means a door. Weeks means defrost. Ice on the walls, the shelves or around the vents What it usually means Two causes only: air getting in, or defrost not completing On a tall column the ice builds from below and shows late A heavy door out of square is the commonest way air gets in What to do in the next ten minutes Look at where the frost is.

Yes, until the airflow is affected. Once frost reaches the vents the cabinet will start losing temperature and then it is the more urgent problem. ### Should I unplug it and defrost it fully? It will help temporarily and it will not fix it. If you do, photograph the coil before the ice goes — where it was sitting is the single most useful piece of evidence in this repair. --- **[Read full article: Frost building up inside](https://electroluxmiami.support/symptoms/refrigerator-frost-buildup/)**
