The short answer
On a True Residential freezer, a freezer that runs without holding temperature is usually losing the battle rather than broken: a lid or door that no longer seals, a condenser that cannot shed heat, or a room that has gone too warm for it. Check what it is fighting before you suspect what is inside it. A built-in column is trapped in joinery, so its airflow path runs through a grille someone else installed, and that grille leads the ranking.
What you are actually seeing
- The outside of the cabinet is warm at the sides — Normal on some cabinets, but with the other signs it means heat is not leaving.
- Packages at the top are thawing while the bottom is solid — Air is not circulating, which points at the air path rather than the compressor.
- Ice cream is soft but the cabinet is plainly running — The classic first sign, long before anything thaws.
- NEAR MISS — water on the floor with the contents still frozen — That is a drainage fault and it has its own page.
Causes, most likely first on this freezer
- Warm air walking in continuously past a seal that no longer touches — Ranked first on True Residential: a built-in column door is heavy and carries its own furniture panel, so any hinge wear shows first as a seal that does not meet at the top. On this one, remember that it is a built-in column in joinery, so its air path belongs to the cabinetry as much as to the unit.
- Condenser coil blanketed in dust, lint or grease — Second: it is the single most effective thing an owner can do, and a coil that has never been cleaned is the norm rather than the exception.
- Where the freezer stands is now the problem — Third: heat has to go somewhere, and a cabinet crammed against a wall or standing beside a heat source has nowhere to put it.
- A fault on the refrigerant system itself — Ranked last here, deliberately: it is the least likely of these and the only one that is not an owner job, so everything above it is worth clearing first.
Check in this order, and why
- First — shut the lid or door on a strip of paper at several points and pull — It is free, it takes ten minutes, and it settles the commonest cause before you touch anything else.
- Then — look at the coil behind the grille or at the back of the cabinet — If you cannot see metal between the fins, this is your cause.
- Only then — feel whether the condenser is warm and listen for the compressor cycling — Only after the seal, the coil and the room have been dealt with, which is why it comes after everything above it.
What an owner can safely check
- Clean the sealing faces and test the seal all the way round — Wipe frost and crumbs off both the gasket and the face it meets, then test with a strip of paper at top, bottom and both sides.
Tools: cloth, paperAbout 15 min
- Give the cabinet air and get it away from any heat source — Pull it clear of the wall, clear whatever is stacked on top or beside it, and check the grille is open.
About 15 min
- STOP before testing anything electrical with the power on — The checks above are all cold checks. Anything that needs power applied is where an owner check ends.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before any panel comes off, and let a capacitor discharge before you reach in. A freezer full of food is extremely heavy — empty it before you move it, and walk it rather than dragging it. Never chip frost off with a knife or a screwdriver: the evaporator tubing is soft, and a puncture turns a cheap fault into a scrapped cabinet.
When it stops being an owner job
Call once the seal, the coil, the clearance and the power have all been cleared and the cabinet still will not hold. Call sooner if the compressor buzzes and stops repeatedly, if there is oil visible around the tubing, or if the cabinet is warm at the sides and the coil is clean.

What this page does not cover
This page is written for the True Residential freezer as a class, not for one family or one model line. Where a family-specific page exists for your unit it is linked above and it is the more specific answer. Deliberately not here: part numbers, wiring colours, torque figures and any measured value, all of which differ by family.
