The short answer
An integrated column that will not hold temperature is usually failing at its door: the weight of the furniture panel has pulled the appliance door out of alignment, so the gasket lifts and warm humid air enters all day. Restricted ventilation in the joinery comes next, then blocked internal vents, and the sealed system is last.
What you observe
- Condensation on the inside walls and the door — Humid air is entering continuously through a gasket that is not sealing.
- The compressor runs almost without stopping — It cannot satisfy its sensor against a continuous heat load.
- Cold at the top and warm at the bottom — Internal vents are blocked rather than the whole column failing.
- NEAR MISS — heavy frost behind the rear panel — That is a defrost fault, and a full defrost has to come before anything else.
Causes, most likely first on this brand
- A furniture door pulling the appliance door out of alignment — First on an integrated column: the panel is heavy, the hinges and rails settle over months, and the gasket then lifts at the top corner where nobody looks.
- Restricted ventilation in the joinery — Second. A flush-installed column takes air at the plinth and exhausts it at the top, and joinery altered after installation can close that path without anyone realising.
- Internal vents blocked by food — Third, and the cause of a cold top with warm drawers: the cooling is distributed through vents at the back, and a row of tall containers starves everything below them.
- A stalled defrost or a sealed-system fault — Last. Ice behind the rear panel blocks the fan's path, and past that the diagnosis needs instruments and is not owner work.
Check in this order, and why
- Test the appliance door gasket with paper at the top corners — This is the leading cause and it takes two minutes to prove.
- Check the ventilation path at the plinth and above the column — Joinery closed after installation is a common and invisible cause.
- Look at the internal vents and what stands in front of them — A cold top with warm drawers names this at a glance.
- Only then treat it as defrost or sealed-system — Both mean panels off or the column drawn out of its opening.
What an owner can safely check
- Move perishables to another refrigerator or a cooler — A refrigerator holds food safely at forty Fahrenheit, four Celsius, or below.
Tools: cooler, iceAbout 25 min
- Test the gasket all the way round with a sheet of paper — Pay particular attention to the top edge and the hinge side.
Tools: paperAbout 15 min
- Clear and vacuum the plinth grille and check the top vent — Both ends of the airflow path have to be open.
Tools: vacuum, torchAbout 25 min
- Re-arrange the contents clear of the internal vents — Leave a gap in front of every vent at the back.
About 20 min
- Defrost fully if there is frost behind the rear panel — Cooling returning afterwards confirms the defrost system.
Tools: towelsAbout 90 min
Before you open anything
Safety
Switch the column off at its breaker before removing the plinth grille or any interior panel — a capacitor can hold a charge after the power is off. Never chip or heat ice off an evaporator. An integrated column with a furniture door fitted is front-heavy and must never be drawn out of its opening by one person; the door will tip it.
When to call a technician
Call when the gasket seals, the ventilation path is open at both ends, the vents are clear, a defrost has been tried, and the column still will not hold temperature. Re-hanging a furniture door to correct the appliance door's alignment is installer work, because the panel position is set against the whole kitchen run. A condenser that stays cold while the compressor runs is a sealed-system call.

What this page does not cover
This page describes fully integrated refrigeration columns as a class rather than a single model. A family- or model-specific page carries what is deliberately absent here: furniture door weight limits, rail and hinge specifications, niche and ventilation dimensions, and defrost component identifiers.
