The short answer
A built-in AGA that will not cool is usually not breathing. Clear the front grille and check nothing has been fitted across it. A heavy panelled door that no longer self-closes is second. A cabinet aperture tighter than the unit was designed for is third, and a fan or sealed-system fault is last.
What you observe
- The front grille is covered or matted with dust — The unit has no other air path.
- It got worse after a kitchen refit — A plinth or panel fitted across the ventilation.
- The door rests ajar instead of self-closing — Worn hinges under a heavy furniture panel.
- The cabinet runs continuously and stays warm — Heat is not leaving the enclosure.
- NEAR MISS — warm after a big restock — Normal recovery. Give it a day.
Causes, most likely first on this brand
- Front grille blocked or matted — First because it is the only air path a built-in has. Dust mats across it over a year or two, and a fitted plinth can close it entirely, which suffocates a perfectly healthy machine.
- Heavy panelled door no longer self-closing — Second, and specific to an integrated installation: the furniture panel adds weight the hinges must carry, and once they wear the door rests a fraction open all day.
- Cabinet aperture tighter than specified — Third: the opening is designed with clearances around and above the unit, and a joiner who lined it or built it tight leaves the machine no room to shed heat.
- Condenser fan or sealed-system fault — Last. Its tell is a cabinet that will not cool with a clear grille, a closing door and a proper aperture, and it needs a technician.
Check in this order, and why
- Look at the front grille and clear it — Free, and it is the top cause on this class.
- Check nothing has been fitted across the ventilation — Refits and new plinths are a common trigger.
- Open the door part-way and let go — A door that does not swing shut is the second cause.
- Feel whether warm air leaves the grille at all — Left until here because it points at the fan.
What an owner can safely check
- Remove and clean the front grille thoroughly — Vacuum the mesh and the space behind it.
Tools: vacuum, soft brushAbout 30 min
- Check the plinth and any panel across the front — Ventilation openings must stay open after any refit.
Tools: torchAbout 20 min
- Open the door part-way and check it swings shut — A door that rests open warms the cabinet all day.
About 15 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 if it will not cool with a clear air path — Fan and sealed-system work is a service call.
Before you open anything
Safety
Isolate the unit at its spur or unplug it before removing the grille or any panel; a capacitor can hold a charge after the power is off, and a built-in appliance is often fed from a socket hidden behind cabinetry. Never open a sealed refrigerant line. 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 grille is clear, the ventilation is open, the door self-closes and seals, and the cabinet still will not hold temperature — the condenser fan or the sealed system is then the answer. Call a kitchen fitter instead if the aperture or the plinth is strangling the unit, because that is joinery rather than refrigeration.

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: aperture and clearance dimensions, hinge and fan part identifiers, refrigerant charges and fault-code meanings, all of which differ between the built-in column, under-counter and integrated families.
