Symptom
Electrolux frost building up inside
A no-frost cabinet that is building frost is telling you one of two things: moist air is getting in, or the defrost cycle is not completing. On a 33-inch column the geometry makes this worse than on a small box — the evaporator is tall, ice builds from the bottom upward, and by the time anything is visible on the top shelf there is a great deal of it out of sight behind the rear panel.

Three ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
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.

None of it needs tools, and all of it makes the visit shorter.

01
Look at where the frost sits
Even through the box, or concentrated at the vents. Two different repairs.
-
02
Close the door and watch the seal
A gap you can see at one corner is the whole explanation.
-
03
Note how quickly it comes back after clearing
Days means a door. Weeks means defrost.
How it shows up
What people describe when they call
A shortcut
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem before anybody opens anything, which is why it is worth photographing before it clears.

About Electrolux frost building up inside
What to do in the next ten minutes
Look at where the frost is. 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.

Questions about Electrolux frost building up inside
Is it safe to keep using?
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.
