Symptom
Viking frost building up inside
Ice at the back wall, on the evaporator cover, or around the drawers. It is a defrost condition, and left alone it eventually blocks the airflow and produces the warm-refrigerator call as well.

Five 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 defrost heater
Gone open, so the ice never gets cleared between cycles. It is a contained repair and a common one.

The defrost thermostat or sensor
The heater works and is never asked to. Same symptom, different part.

A door letting humid air in
In this climate that is a real source of frost rather than a footnote, and it costs nothing to correct.
Refrigerator door & panel alignment from $165 -
A blocked drain
Melt water that cannot leave freezes where it stands, and then the drain is doubly blocked.

01
Where exactly is the ice
On the back wall, at the evaporator cover, or around a drawer. The location is diagnostic.
-
02
The paper test on the seals
Humid air is a frost source here in a way it is not in a dry climate.
-
03
Does it return after clearing
Frost that comes back within days is defrost. Frost that does not is a one-off — a door left open, or a power interruption.
-
04
Look for water where it should not be
A blocked drain often shows as water under a drawer before it shows as ice.
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.
If there is no code at all
The data plate is inside the cabinet, upper left wall or behind the grille. All models

About Viking frost building up inside
The fastest diagnosis is the code
Check the door seals first. Warm humid air getting in is where a good deal of frost comes from in this climate, and it is free to check — the paper test again, all the way round.
Two problems in sequence
A defrost circuit that has stopped does not announce itself. Ice builds gradually, nobody notices, and then one day the airflow between compartments is blocked and the refrigerator goes warm while the freezer is perfect. Those are one condition arriving in two stages.
Where humidity comes in
Every door opening in this city brings in air carrying considerably more moisture than the manual assumed. A seal that has hardened turns that from a footnote into the main source, which is why the door is checked before the heater.

Questions about viking frost building up inside
Should I defrost it manually?
It will get you working again for a while and it is worth doing if the airflow is already blocked. It does not fix anything, and the ice will come back on the same schedule it came the first time.
Is frost normal in Florida?
A little more than elsewhere, yes — every door opening brings humid air in. What is not normal is ice that builds steadily and returns after clearing, and that is a defrost circuit rather than the climate.
The refrigerator side is warm and there is ice at the back.
Those are the same problem seen twice: ice has blocked the path the cold air takes between compartments. Clearing the ice will help temporarily; the defrost circuit is the actual repair.
