The short answer
On Aviva ARBM the honest first answer is that a compact bottom-mount refrigerator that will not hold temperature is far more often a heat-rejection or airflow problem than a dead compressor. This is a cabinet whose cold is made in the lower freezer compartment and moved upward into the fresh-food space through a duct and a fan, and every one of those elements can stop the cabinet cooling while the machine still sounds perfectly normal.
What you observe on these models
- The cabinet is warm and the machine is plainly running — A unit that is working and never arriving is the presentation this page is about, and it is not the same fault as a cabinet that is silent.
- One part of the interior is right and another is not — A temperature that varies across the cabinet is an airflow report.
- The cabinet recovers overnight and drifts by day — That pattern points at the room rather than the machine, and it is the single most useful thing an owner can notice.
- NEAR MISS — the cabinet is silent and nothing is cold — That is a power, start-relay or control fault rather than a cooling fault, and it belongs on a different page.
Causes, most likely first on ARBM
- Blocked airflow inside the cabinet — Cold that is made correctly and then cannot circulate produces exactly the same complaint as cold that was never made: a warm cabinet with a machine that is plainly working. The duct that lifts cold from the lower compartment is narrow by design and is the first thing a tall item blocks. It leads the list on Aviva ARBM because these are compact bottom-mount refrigerators — a bottom-mount refrigerator line concentrates this fault in a way a full-size machine does not.
- A failed circulation or condenser fan — A fan that has seized, slowed or lost its supply removes the moving air the design depends on, and the fault appears as a cabinet that is cold in one place and warm everywhere else.
- A dirty or obstructed condenser — The condenser is where the heat leaves. Once it is blanketed in dust or fed its own warm exhaust, the circuit cannot reject heat and the cabinet warms no matter how long the compressor runs.
- How the cabinet is loaded — A cabinet packed to the vents, or loaded warm in one go, reports as a cooling failure for days before it is one. Last on this list, and the item that every cause above it can imitate exactly.
Check in this order, and why that order
- Start at the heat path: compare the two compartments against each other — which one is right tells you where in the airflow path the fault sits — The freezer drawer or door and the rear interior panel behind it, with the machine pulled forward far enough to reach the base bay.
- Look at how the cabinet is loaded and where the air returns — The fresh-food space is downstream of the freezer, so it is always the compartment that shows a fault first and the one that recovers last, so pull the load a hand-width off the rear wall and give it a day before concluding anything.
- Only then consider the sealed system — By this point four cheaper causes are eliminated.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off.

When to call a technician
Call when both compartments are wrong together, or the freezer is right and the duct is clear and the fresh-food space still will not hold. Call immediately if you can smell burning, if the machine trips protection repeatedly, or if there is oil rather than water in the machine bay — oil outside the tubing means the circuit is open, and every hour it runs after that costs more to put right. Check the plate before acting on any of this. ARBM is a bottom-mount refrigerator line, and the ranking above is written for that construction rather than for the brand as a whole.
