The short answer for the AUF models
On the Agostino AUF refrigerator models, a cabinet that runs but will not get cold leads with a door gasket that no longer seals rather than with the cause the brand-generic article opens on. The spine for the AUF family lists a few codes from the same series, which means one design with variants rather than several designs.
What you observe on these models
- Food is spoiling sooner than it used to — A refrigerator holds food safely at 40 degrees Fahrenheit, 4 degrees Celsius, or below. Above that, the change shows in the food before it shows anywhere else.
- The cabinet is warm but you can hear it running — The compressor hum is there. The air inside is not cold, and it has not been for a while.
- A sheet of frost has built on the back wall of the freezer — Not the usual light dusting — a solid layer that has been growing for weeks.
- NEAR MISS — the cabinet is silent and nothing is cold — That is a no-power or start-relay fault, and it belongs on a different page than this one.
Causes, most likely first on the AUF family
- A door gasket that no longer seals — A door that is not closing onto its seal is an open door as far as the cabinet is concerned. It is also the easiest fault on this list to confirm without a tool. Ranked first here.
- An evaporator fan that has stopped turning — Cold is made in one place and has to be carried to the other. When the fan stops, the freezer can still be cold while the fresh-food side is not. Second.
- A sealed-system or compressor fault — The expensive end: refrigerant loss, a restriction, or a compressor that turns without compressing. It is ranked last because it is genuinely the least common of the causes here.
- Body: The cause that moves up on these models is a door gasket that no longer seals; what moves down to make room for it is a condenser coil that cannot shed its heat, which is where the brand-generic article for this symptom opens.
Check in this order, and why
- Close the door on a strip of paper and pull it out at several points — First: Anywhere the paper slides free, the seal is not making contact.
- Listen at the freezer for the fan, then open the door and listen again — Second: On most cabinets the door switch cuts the fan. If the sound changes, the fan is alive.
- Put a thermometer in a glass of water on the middle shelf overnight — Third: It reads the cabinet rather than the door, and it separates a real fault from a door that is opened often.
Before you open anything
Safety
Nothing comes off this cabinet until it is unplugged or its breaker is switched off — a capacitor holds a charge after the power is gone, and a fan inside can start without warning. Never defeat a door switch to keep a fan running while you look: it is there to stop a blade turning next to your hand. A refrigerator holds food safely at 40 degrees Fahrenheit, 4 degrees Celsius, or below.

When to call a technician
If every check above comes back clean, the remaining answer is a sealed-system or compressor fault, and that is the one that needs a technician rather than an afternoon. Call immediately, and unplug the cabinet first, if you smell burning, see oil around the compressor, or hear a hiss with a sharp smell.
