The short answer
A retro Agostino that runs warm is usually set rather than broken. Turn the dial colder, leave a thermometer inside overnight and judge it then. A cabinet pushed flat to the wall is second, a door that rests ajar third. A sealed-system fault is last and, on this kind of cabinet, usually ends it.
What you observe
- The dial is on a middle setting and food is warm — The numbers are not temperatures.
- It is fine in winter and poor in summer — The same setting, a much harder job.
- The cabinet is pushed flat against the wall — The back cannot shed its heat.
- The door rests slightly open instead of latching — A heavy retro door on tired hinges.
- NEAR MISS — warm after a large shop — Normal recovery in a small cabinet.
Causes, most likely first on this class
- Dial set too mild for the room — First because the numbers invite exactly this mistake. A middle setting is not a temperature, and in a warm kitchen it leaves the cabinet well short of where food needs to be.
- Cabinet pushed flat to the wall — Second, and driven by the styling: these are bought to look good and sited accordingly, which closes the air gap the back of the unit depends on.
- Heavy door no longer latching — Third: a substantial retro door with a decorative handle puts real load on its hinges, and once they tire the door rests open by a fraction all day.
- Sealed-system or compressor fault — Last, and decisive here. Parts and service for a cabinet like this are hard to come by, so a refrigeration fault is usually the end of it rather than a repair.
Check in this order, and why
- Put a thermometer inside and leave it overnight — The only honest reading from an uncalibrated dial.
- Turn the dial colder and repeat the measurement — Free, and it settles most of these outright.
- Pull the cabinet clear of the wall — The second cause, and it costs nothing.
- Check the door latches and stays shut — Left until here because it rarely explains it alone.
What an owner can safely check
- Leave a thermometer inside overnight and read it — Record the number before changing anything.
Tools: thermometerAbout 20 min
- Turn the dial colder and leave it a full day — Judge by the thermometer, not by how it feels.
About 20 min
- Pull the cabinet forward and leave air behind it — Clean any coil or skin at the back while it is out.
Tools: soft brushAbout 30 min
- Open the door part-way and check it latches shut — Then test the seal on a sheet of paper all round.
About 20 min
- STOP HERE if it will not hold temperature at its coldest — Sealed-system work needs a technician and a licence.
Before you open anything
Safety
Unplug the cabinet before removing a panel or reaching behind it; a capacitor can hold a charge after the power is off. Never open a sealed refrigerant line, and never run the cabinet from a long thin extension lead. Keep a refrigerator at or below forty degrees Fahrenheit, which is four degrees Celsius, and discard food that has been warmer than that for too long.
When to call a technician
Call when the dial is at its coldest, the cabinet has air behind it, the door latches and seals, and a thermometer still reads too warm — the thermostat or the sealed system is then the answer. Ask about parts availability before authorising work, because on a cabinet of this kind they are often the deciding factor.

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: dial calibrations, clearance dimensions, thermostat part identifiers and fault-code meanings, all of which differ between the retro upright, under-counter and worktop families.
