The short answer
The ARB roster records a single model, so nothing on this page has to be hedged across variants, and some entries leave the finish or trim position unresolved, so confirm your own code from the rating plate rather than from the shelf label. A refrigerator in this roster that runs without cooling is usually reporting an airflow restriction rather than a dead compressor. A refrigerator holds food safely at 40 °F (4 °C) or below, and a cabinet that has drifted above that while still running is telling you the cold is being made and not delivered.
What you observe on these models
- Condensation or ice along the door seal — Warm humid room air arriving where the seal is not closing. The frost marks the leak, which makes it the most self-diagnosing symptom on this list.
- It recovers after being emptied and drifts again once refilled — A cabinet short of capacity rather than broken, which points at airflow, seal or condenser rather than at the compressor.
- The cabinet is warm but clearly running — The compressor hum is there and the air inside is not cold. A running cabinet that will not cool is reporting a restriction, not a failure.
- The freezer side is cold and the fresh-food side is not — Cold is made in one place and moved to the other. When only one compartment fails, the route between them is the suspect.
Causes, most likely first on the ARB line
- Frosted evaporator blocking the air path — Ranked first on this roster: the evaporator sits behind the rear interior panel and a frost sheet on it stops airflow before it stops heat transfer, so the cabinet warms while the compressor keeps running normally.
- Vents blocked by stored food or an overfilled shelf — It ranks second here because it is free to correct, extremely common after a big shop, and produces exactly the one-compartment-warm pattern owners describe.
- Condenser choked or the cabinet boxed in — Ranked third on this roster: it worsens in hot weather and in confined spaces, so a cabinet that only misbehaves in summer is pointing straight at it.
- Start components or the sealed system — Ranked last on this roster: a compressor that will not come up, or a circuit that has lost charge, produces a cabinet that is not cold at all rather than one that is not cold enough.
- Body: The ranking here keeps the brand-generic order, and what the ARB line changes is the order of the checks beneath it: the roster leaves the finish and trim position unresolved on some entries, so the door and its seal are the part of the cabinet you have to confirm by eye.
Check in this order, and why
- Confirm the finish and door panel on your own cabinet — Some entries on this roster leave the finish and trim position unresolved, so the visible parts of the cabinet, the door and its seal included, have to be confirmed by eye rather than read off the code.
- Look at the rear interior wall for a frost sheet — A layer thick enough to hide the surface underneath explains the complaint on its own, and it means the defrost side is worth investigating.
- Clear the back of every shelf and find the vents — Leave a hand's width clear at the rear of each shelf, then give the cabinet a day before judging.
- Clean the condenser and give the cabinet air on every side — With the power off, clear the coil or compartment and pull the cabinet clear. Allow a day before judging the result.
Before you open anything
Safety
Switch off at the breaker before any panel comes off and treat the space behind it as live until proved otherwise. Defrost with the doors open and the power off, never with a heat gun or an open flame, and never by chipping at the surface. Keep meltwater away from the supply cord.

When to call a technician
Call when a full defrost, a cleared condenser and a clean paper test have all failed to hold the cabinet for a day, because that pattern eliminates everything an owner can reach. Call sooner if only one compartment is affected and the vents are already clear, because a damper or an interior fan needs a panel off. Either way, move the perishable load first: it will not survive the diagnosis.
