The short answer
The AUFM roster covers a small group of closely related cabinets, and its entries differ only in the trailing finish position. 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 AUFM 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.
- Evaporator fan not running — Ranked third on this roster: a fan that was chirping before it stopped had been meeting frost, which means there are two faults to resolve rather than one.
- 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 AUFM line changes is the order of the checks beneath it: 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
- 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.
- Listen for the fan with the door switch held in — Press the door switch and listen inside. Silence where there should be airflow points at the fan or its supply.
- 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.
