The short answer
Every model in the ABMA roster shares one capacity core and differs only in finish or trim, so the cabinet behind them is the same machine throughout, and its entries differ only in the trailing finish position. When one compartment is cold and the other is not, the cabinet has an airflow problem rather than a cooling problem, because on cabinets of this kind the cold is made in one place and moved to the other. That single observation redirects the whole diagnosis.
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 ABMA line
- Vents blocked by stored food or an overfilled shelf — Ranked first on this roster: it is also the cause most likely to come back, because the habit that caused it has not changed.
- Frosted evaporator blocking the air path — Ranked second 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.
- Condenser choked or the cabinet boxed in — It ranks third here because it produces a continuous-run complaint with nothing visibly wrong inside the cabinet, which is why it is so often missed.
- Start components or the sealed system — Ranked last on this roster: reaching it honestly is a useful result, because it turns the question into repair or replace rather than keep looking.
- Body: Where this ranking departs from the brand-generic order is vents blocked by stored food or an overfilled shelf, which moves up on the ABMA line because this roster is two or three closely related cabinets, so the order follows how those particular machines are built rather than an average across the brand.
Check in this order, and why
- 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.
- 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.
- 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.
- 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
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.
