The short answer for these models
Warm cabinet, compressor audibly running: on the ARC line that combination narrows the field immediately. This family spans a range of model numbers rather than a single cabinet. The ranking below is set by how these cabinets are built, and it differs from the generic order in which cause sits first.
What an owner actually sees
- Food at the door is spoiling faster than food at the back — A door-side gradient usually means the seal is losing cold air rather than the cooling system losing capacity.
- The cabinet recovers overnight and drifts warm during the day — A machine that is only just coping. It points at heat rejection or at how often the door is opened rather than at a failed part.
- The cabinet is warm while the compressor is clearly running — You can hear or feel the unit working, yet nothing inside comes down to temperature. That pairing rules out most no-power faults before you touch anything.
- NEAR MISS — water pooling under the crisper with normal temperatures — That is a blocked defrost drain, covered on the water-leak page for this family, not a cooling failure.
Causes, most likely first on the ARC line
- The compressor start device — Ranked first here because the pattern the owner describes — runs, stops, tries again — is the classic signature of a start relay on its way out rather than of anything in the air path.
- Thermostat or control board — Second. On these models the control is a simple device with a sensing element, and when that element loses contact with its mount the control reads the wrong temperature and satisfies early.
- Condenser airflow and dust — Third. A coil packed with dust or a cabinet pushed back against a wall both produce the same outcome, and on this family the coil is easy to reach from behind.
- Door seal and loading — Fourth. Overloading blocks the internal vents on cabinets of this size, and a seal that leaks adds moisture that ends up as frost.
- Sealed system — Last. It is the only item here that cannot be checked from outside the cabinet, and the only one that is licensed work.
The order to work in on these models
- Establish which part of the cabinet is warm — A whole-cabinet failure and a one-compartment failure have almost nothing in common, and this question separates them in seconds.
- Leave it a full day and measure again — Cabinets of this size need hours to recover, so an immediate re-check after any change tells you nothing.
- Inspect the seal and the evaporator area for ice — Now worth doing: if the temperature has not moved, the fault is not in the loading.
- Check the fan and the condenser last — Both need a panel off or the cabinet pulled out, so they sit at the end of the owner-side sequence.
Before any panel comes off
Safety
Before a panel comes off, unplug the appliance or switch off its breaker; a capacitor can hold a charge after the power is off. Sharp edges and a fan blade sit immediately behind most covers on cabinets of this build, so work with the power isolated rather than with the door switch propped. Refrigerant work is licensed work and is out of scope for an owner. While the cabinet is warm, treat the food by the clock rather than by the look of it: a refrigerator holds food safely at 40 °F (4 °C) or below and a freezer at 0 °F (−18 °C) or below. Above those, move anything perishable to a cooler with ice and keep the door shut.

Where owner work stops
Call once the owner-side checks are clean: seal, loading, clearance and a visible look at the evaporator area. Call immediately if you see oil at the compressor or smell burning, because oil outside the tubing means the sealed system is open and every further hour of running makes the repair larger. On the ARC line the line between the two jobs is the panel: what you can reach with the cabinet emptied is owner work, what needs the machine dismantled is not.
