The short answer
Work out which machine you have first: a static cabinet with a cold plate and a frost-free one with a vented panel fail in different ways. After that, a dusty condenser or a cabinet pushed against a wall is the leading cause on both. A tired door seal comes third, and a thermostat or sealed-system fault last.
What you observe
- A cold plate on the back wall inside — A static cabinet. No defrost system to stall.
- A vented panel in the freezer instead — Frost-free, so a stalled defrost is possible.
- Dust matted across the coil at the back — Heat cannot leave. Common to both types.
- The seal no longer grips a sheet of paper — Warm air leaking in continuously.
- NEAR MISS — warm after a big shop — Normal recovery. Give it a day.
Causes, most likely first on this brand
- Condenser dusty, or the cabinet pushed against a wall — First because it applies whichever machine you have, and because an entry-level cabinet rejects its heat from a coil on the back skin that nobody ever cleans or leaves space around.
- Stalled defrost on a frost-free cabinet — Second, but only if yours is frost-free: frost blocks the vented panel, airflow stops, and the fresh-food side warms while the freezer stays cold. On a static cabinet this cause does not exist.
- Door seal tired or the door not closing — Third: entry-level hinges and seals give up sooner, and a door that rests a fraction open warms the cabinet continuously without ever looking wrong.
- Thermostat or sealed-system fault — Last. At this price point a refrigeration fault is usually the end of the cabinet, so establish everything above before authorising any work.
Check in this order, and why
- Read the rating plate and look at the layout — It decides which of the causes below can apply.
- Pull the cabinet out and look at the coil — Free, and it applies to every machine of this kind.
- On a frost-free cabinet, look for frost behind the panel — A frost slab names a stalled defrost.
- Test the door seal with a sheet of paper — Left until here because it rarely explains it alone.
What an owner can safely check
- Find the rating plate inside and note what it says — Photograph it. Any parts enquiry will need it.
About 15 min
- Unplug and clean the coil and the floor beneath it — Brush and vacuum, then leave a gap behind the cabinet.
Tools: coil brush, vacuumAbout 45 min
- On a frost-free cabinet, defrost it fully and retest — Cooling normally afterwards points at the defrost system.
Tools: towelAbout 60 min
- Close the door on a sheet of paper and pull — It should drag all round, not only in places.
About 15 min
- STOP HERE before testing thermostats or defrost parts — All of them sit on live terminals inside the cabinet.
Before you open anything
Safety
Unplug the refrigerator before removing a panel or reaching behind it; a capacitor can hold a charge after the power is off. Never chip frost off a cold plate or an evaporator with a blade — the tubing is thin and a puncture releases refrigerant under pressure. Keep a refrigerator at or below forty degrees Fahrenheit, which is four degrees Celsius, and discard food that has been warmer for too long.
When to call a technician
Call when the coil is clean, the cabinet has air behind it, the seal grips and it still will not hold temperature — the thermostat, the defrost parts or the sealed system is then the answer. Give them the rating plate details rather than the brand name, because that is what identifies the parts. Ask for the cost against a replacement first.

What this page does not cover
This page is written for the brand and the appliance class, not for one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and you should start there. Deliberately absent: thermostat and defrost part identifiers, clearance dimensions, refrigerant charges and fault-code meanings, all of which differ between the static single-door, frost-free top-freezer and under-counter families.
