What is happening, in three sentences
On the FFFDS group a warm cabinet with an audible compressor points first at heat rejection — if the condenser cannot shed heat to the room, the refrigerant never condenses and nothing gets cold however long the unit runs. The seal is the second place to look and the evaporator the third. That order is set by what you can inspect without opening the cabinet.
What you actually observe
- The freezer section still works but the fresh-food section does not — Cold is being made and not distributed, which points at the air path rather than the sealed system.
- Condensation or sweating around the door frame — Warm room air is reaching the cold surface, and the seal is the usual route.
- The machine starts, runs briefly and stops again — A short cycle with a click at each end usually means the motor is going out on its overload instead of running.
- NEAR MISS — only the ice is soft and everything else is fine — A freezer section that is merely too warm while the fridge section is right is a control or damper question, not a cooling failure.
What it usually turns out to be, in order
- Condenser coil choked, or no clearance around the cabinet — Heat leaves the refrigerant at the condenser, and a coil packed with dust or a cabinet pushed tight into a recess cannot do it. Ranked first on FFFDS: every model under this stem has the part, so it is the one cause that cannot be excluded by knowing which code you own.
- Evaporator iced over, so the air path is blocked — Frost belongs on the evaporator; a solid sheet across it does not. It ranks second on FFFDS rather than first only because the cause above it is quicker to exclude, not because it is rarer.
- Thermostat, sensor or control set wrong or reading wrong — A dial knocked to its warmest position, or a sensor reading colder than the cabinet really is, both stop the machine asking for cold. Third on this family, and the rank where the cause stops being obvious from the doorway.
The diagnostic order
- Where to begin on FFFDS models — Three of the causes above can be excluded without a tool, and this order puts every one of them ahead of anything that needs the cabinet moved or a panel off.
- Look at the condenser and at the clearance around the cabinet — Dust on the coil and a tight recess produce the same result, and both are visible without a tool.
- Look for a frost sheet on the freezer rear wall — A solid layer rather than a dusting confirms the airflow cause before anything is dismantled.
- Check the setting, then watch whether the machine cycles — Set it to the middle of the range and see whether the compressor responds within a few minutes.
Before you touch anything
Safety
Pull the plug or open the breaker before any panel comes off — a capacitor can hold a charge after the power is off. Pulling an FFFDS cabinet out to reach the back is the other half of the hazard: it is a heavy, top-loaded box on a hard floor, so walk it out rather than dragging it, and keep the door shut while it moves so the weight stays where you expect it.

When to call a technician
Call once the owner-side checks above are clean and the cabinet is still wrong. Call without finishing the list if the fault is on the sealed system — if you can see oil at the compressor or at a tubing joint, or you smell burning — because oil outside the tubing means the system is open, and every hour the unit runs after that costs more to put right.
