The short answer
The ARK roster records a single model, so nothing on this page has to be hedged across variants, and it is the only entry on that roster, so the rating plate confirms your cabinet in a single step. The distinction that matters here is between a cabinet that is not cold and one that is not cold enough. The second is far more common on these models, it is progressive, and most of it is owner-diagnosable; the first points at the start components or the sealed circuit and is a different repair.
What you observe on these models
- 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.
- Frost building as a sheet on the rear interior wall — A layer rather than the usual light dusting. Frost is an insulator and it blocks the air path at the same time, so it does double damage.
- The compressor never cycles off — The cabinet is no longer reaching its set point, so the control never tells it to stop. This is the clearest sign that a restriction is at work.
Causes, most likely first on the ARK line
- Frosted evaporator blocking the air path — It ranks first here because it explains the commonest version of this complaint, the one where the cabinet is cool rather than warm and the running never stops.
- Door seal not closing, or a door left ajar — Ranked second on this roster: seals fail gradually, which is why the cabinet seems to have been fine until it suddenly was not.
- Vents blocked by stored food or an overfilled shelf — Ranked third on this roster: cold air has to reach the compartment through specific openings, and a shelf packed to the back wall closes them as effectively as a failed fan would.
- Start components or the sealed system — It ranks last because every cause above it is more common and cheaper, and because arriving here first is how working cabinets get replaced.
- Body: Where this ranking departs from the brand-generic order is door seal not closing, which moves up on the ARK line because this roster is a single cabinet rather than a line, so the order is what that one machine makes likely and not an average taken across several.
Check in this order, and why
- 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.
- Close the door on a strip of paper at several points and pull — Anywhere the paper slides out freely is admitting air. Check the whole perimeter, not just the handle side.
- 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.
- Have the circuit assessed rather than guessed at — This needs gauges and a licence. Oil on the tubing at the back means the circuit is already open and it should stop running.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Never chip frost off the rear interior wall with a sharp tool, because the tubing behind it is thin-walled and a nicked tube turns a defrost into a replacement. A refrigerator holds food safely at 40 °F (4 °C) or below, so move anything perishable to a cooler before you start rather than after.

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.
