The short answer
On an AGA refrigerator, not cooling or not freezing most often comes back to cabinetry closing off the grille the cabinet breathes through, with a blocked or fouled condenser, or no clearance to reject heat close behind. The mass of the door and the precision of the built-in installation put alignment and levelling at the top of the list, because a cabinet that is out of level takes the door, the seal and the drain with it. That puts the first move in your hands rather than a technician’s: work the checks below in order and stop at the first one that explains what you are seeing.
What you are seeing
- What this fault looks like, and which observations point somewhere else.
- the compressor runs far longer than it used to, or never stops at all
- food in the door warms first, and anything at the back stays coldest
- the back wall of the fresh-food section is either heavily frosted or completely dry and warm to the touch
- Not this fault: if the cabinet is cold but the ice supply has stopped, the fault is in the ice system rather than in cooling
Ranked causes on this platform
- Ranked for an AGA refrigerator, which runs a probe-driven electronic control with a service display behind the grille. No measured frequency exists for this address, so the order is platform judgement rather than a share.
- Cabinetry closing off the grille the cabinet breathes through — Why: A built-in rejects all its heat through one grille, so a decorative panel or a fitted plinth across it starves the condenser completely.
- A blocked or fouled condenser, or no clearance to reject heat — Why: Every other component can be perfect and the cabinet will still fail to hold temperature if the heat has nowhere to go.
- An evaporator fan that is not moving air — Why: On a forced-air cabinet the fan is the only thing carrying cold to the fresh-food side, so it fails as a warm fridge with a cold freezer.
What to check, in order
- The order follows the ranking above: most likely and cheapest first, nothing needing a meter until everything else is eliminated.
- Cabinetry closing off the grille the cabinet breathes through — Because: a built-in rejects all its heat through one grille.

Checks you can safely do yourself
- Isolate the appliance before any panel comes off, and stop at the first step that explains the fault.
- Check the grille is clear and unobstructed across its whole width and that the cabinetry above it is vented as designed. — Tools: a torch — Time estimate: a quarter of an hour
- Clear the grille and the coil, and give the cabinet clear air on the sides and behind before changing anything. — Tools: a coil brush and a vacuum — Time estimate: a quarter of an hour
- Open the freezer and press the door switch by hand; listen for the fan and feel for airflow at the vents. — Tools: nothing — Time estimate: a few minutes
- Stop condition: Stop there: the next step means metering live terminals or opening a sealed system.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off. Never open a sealed refrigeration circuit; refrigerant work is licensed work and a punctured line ends the life of the cabinet. A loaded cabinet is heavy and top-sided — move it with two people and empty the door first.
When to call a technician
Call a technician when the cabinet still will not hold temperature after the airflow, seal and control checks are clean, when the evaporator ices up again within days of being cleared, or when the compressor is hot and silent rather than running. Sealed-system work is licensed work and is not an owner repair under any circumstances.
