The short answer
On the ABB refrigerators this complaint is far more often about air than about the cooling system: the compressor is still running, and something has stopped the cold reaching the food. On these models a blanketed condenser coil is the first thing this page would have you rule out. The list below ends with the one cause on it that is not owner work.
What you observe on these models
- The freezer still works and the fresh-food side does not — A split like that points at air movement rather than at cooling.
- The appliance never cycles off — It runs on and on without ever reaching the setting.
- Frost has built across the freezer back wall — A sheet, rather than the usual light dusting.
- NEAR MISS — the appliance is silent and nothing is cold — That is a no-power or start-circuit fault and it belongs on a different page.
Causes, most likely first on this family
- Condenser coil packed with dust or pet hair — A blanketed condenser cannot reject heat, so the compressor runs longer and longer for less and less cooling until it never catches up. It leads because it is the likeliest of the set on these cabinets. The masked positions are trim rather than mechanism, so it holds across the line.
- Cold control or thermistor reading wrong — A failed sensor gives a cabinet that is steady at the wrong temperature rather than one that drifts, and that steadiness is the clue. Second: common enough on these models to come before anything below it.
- Start relay or compressor overload — An overload that keeps tripping means the compressor is being asked to work too hard, so find the cause of that load before replacing anything. Third on the list, where the likelihoods start to fall away.
- Sealed-system or compressor fault — This sits last for a reason: it is the least common cause of the complaint and the only one that is not an owner repair. Last of the set listed here, and the least likely of them on this family.
- Body: Against the brand-wide order, installation causes move up and wear causes down — the masked positions are trim, so the builds share an age band and the way the cabinet was fitted counts for more.
Check in this order, and why
- Pull the appliance out, take off the lower rear cover or the toe grille and look at the coil for a felt of dust. — It comes first because it matches the cause ranked first above.
- Leave a thermometer in the compartment overnight and compare what it reads against what the control is set to. — Next in order, following the ranking rather than convenience.
- Listen at the compressor for a short hum followed by a click rather than a steady run. — Last of the set, and only worth doing once the others are clean.
Before you take a panel off
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Leave the door switch wired as it is: it cuts power to the evaporator fan for a reason. Keep the doors shut meanwhile and move perishables to a cooler: a refrigerator holds food safely at 40 °F (4 °C) or below, a freezer at 0 °F (−18 °C) or below.

When to call a technician
Call once the vents, the seal and the condenser are clean and the cabinet still will not hold temperature: past that the checks are behind a panel. Call at once for a burning smell, a tripping breaker, or oil at the compressor.
