The short answer
A Azure A cabinet that ices repeatedly after being cleared is reporting one of two things: a way in for humid air, or a way out for meltwater that is blocked. Both are owner-checkable on this family, and the order below is set by how these outdoor-rated undercounter cabinets are built rather than by generic refrigerator advice.
What you observe on these models
- A sheet of frost on the rear interior wall — A sheet rather than a dusting is the airflow-closing kind, and it is the version that ends as a temperature complaint.
- Ice under the lowest shelf or basket that returns after clearing — Meltwater that cannot leave.
- Items nearest the rear wall are frozen, the rest is not — On an outdoor-rated undercounter cabinet that is the load touching the cold surface rather than a control fault.
- NEAR MISS — no ice, but the cabinet will not hold temperature — That is a cooling-failure page, not this one.
Causes, most likely first on A
- Room humidity and how often the door opens — Every door opening exchanges the cabinet air for room air, and the water in that air stays behind. A cabinet opened constantly in a humid room ices for no other reason. Ranked first here: outdoor air is the humidity source and it is not going away. Ranked first here rather than further down, because a three-configuration undercounter line gives this cause more opportunities than any other on the list.
- A door seal drawing humid room air — Warm room air meeting a cold surface deposits water, and at these temperatures that water becomes ice at the point of entry — which is why the ice is always worst nearest the leak.
- A set point below what the load needs — A cabinet set colder than it needs to be will freeze its contents and frost its walls, and on a narrow-band cabinet the margin for this is small.
- A defrost cycle that is not completing — Frost that returns as a sheet rather than a dusting means the cycle that should clear it is stalling, and the sheet closes the airflow path down as it grows. Last on this list, and the item that every cause above it can imitate exactly.
Check in this order, and why that order
- Clear the ice completely, with the power off, and note the date — You cannot diagnose ice you cannot see the growth of. Defrost with time rather than heat, and never chip at it — the tubing under the surface is thin-walled.
- Check the seal at every point of the door line — A strip of paper closed in the door and pulled at intervals will find a slack point. On a glass door, check the hinge side, which is the side people never check.
- Find and clear the drain — The front grille and the bay behind it; the cabinet is drawn out of its enclosure before any interior panel comes off. A drain that has blocked once will block again, so clear it properly rather than poking at the opening.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before clearing ice or removing any panel. Never chip, lever or heat ice off an evaporator or an interior wall: the tubing beneath is thin-walled and a puncture ends the cabinet.

When to call a technician
Call when ice returns quickly after a full defrost and the seal, the drain and the set point are all ruled out, because at that point the defrost arrangement or the sensor that governs it is the remaining candidate. Call immediately if you find ice where a line enters the cabinet, or if clearing the ice has exposed damaged tubing. Before ordering anything, match the plate against the A variant table above. The family is a three-configuration undercounter line, and parts that look alike across a brand's other lines often do not fit it.
