What this usually is
The usual answer on this unit is a lid or door seal that is not making contact, with not enough clearance around the cabinet to shed heat behind it. Both are about heat getting in or not getting out, and neither is a parts job. The first checks here are free and they settle most cases.
What you actually observe
- A chest unit is icing up far faster than it used to — Moist air is getting in, which is the seal or the way it is being used.
- The outside of the cabinet is warm to the hand — Heat is being rejected into a space that cannot carry it away.
- NEAR MISS: it freezes fine but leaks water — That is a defrost or drain fault and belongs on the water-leak page.
The ranking: most likely cause first
- A lid or door seal that is not making contact — A seal that has taken a set, or a lid propped by a packet, lets moist room air in all day. The unit ices up fast and still never gets down to temperature. First, and the whole order below follows from it: a freezer is opened less often than a fridge but stays shut on whatever was in the way, so a seal fault runs for weeks before anyone notices.
- Not enough clearance around the cabinet to shed heat — A freezer pushed into an alcove, boxed in with storage or backed tight against a wall cannot reject its heat. Second on this unit, because a standalone freezer ends up in a garage, a utility room or a cupboard, and it is stored around rather than installed.
- Frost build-up on a manual-defrost unit — On a manual-defrost freezer, frost on the walls is insulation. Third on the list, and worth the look because manual defrost is a job that is put off until the unit stops working, which is precisely this fault.
- A sealed-system or compressor fault — A refrigerant leak or a worn compressor produces exactly the same warm cabinet as everything above it, at many times the cost to put right. Bottom of the list, deliberately: it is the least likely cause and the only one that is not owner work, so it is ruled in last and only by a technician.
What to check first, second, third
- Close the lid on a sheet of paper at several points and pull — Free slide anywhere means a gap, and a gap explains everything above.
- Look at what is stacked around, behind and on top of the unit — Boxes on the lid and against the back are the commonest single cause here.
- Look at the thickness of the frost on the cabinet walls — A layer thicker than a finger is already costing you performance.
Owner-side checks, step by step
- Test the seal with a sheet of paper right round the lid, then wash the sealing face — A soiled seal and a set seal behave the same and only one is free to fix.
Tools: a sheet of paper, warm soapy waterAbout 15 min
- Clear a hand's width around the back and sides and take everything off the top — Then give it a full day before judging the result.
About 15 min
- STOP AT THIS POINT if the fault is on the sealed system — Refrigerant is licensed work and the tools for it are not owner tools.
Safety first, and it is not boilerplate
Safety
Unplug the freezer or switch off its breaker before removing any panel or grille. A capacitor can hold a charge after the power is off. Never chip frost away with a knife or a screwdriver: refrigerant tubing runs behind the cabinet walls on most units and a puncture ends the appliance. Do not use a heat gun or an open flame to speed a defrost.
When to call a technician
Call once the seal, the clearance, the coil and the frost are all clean and the cabinet still will not hold, because what is left is the control or the sealed system. Call sooner if the compressor clicks and gives up, if you smell burning, or if the unit trips a breaker.

Scope of this page, and where to go for more
This page covers the White-Westinghouse freezer as a class, not one family or model line. Where a family- or model-specific page exists it is linked here. Deliberately not here: thermostat part numbers, refrigerant charge figures and any sealed-system procedure, all of which differ by family and belong on the page for that family.
