The short answer
The ACFM roster covers a small group of closely related cabinets, and it records the same code twice, once with an unresolved leading character, so those pairs of rows are one cabinet rather than two. When a cabinet here runs continuously and still will not freeze, the compressor is almost always working and something is standing between it and the load. The candidates are a seal that is letting warm air in, frost insulating the cold surface, and a condenser that cannot reject heat, in roughly that order.
What you observe on these models
- The outside of the cabinet is warm to the touch — Some warmth at the sides is normal on cabinets that use the shell to reject heat.
- Water pooling under the load — Frost that has begun to melt between cooling runs.
- It recovered after being emptied and then drifted again — A cabinet that can hold a small load and not a full one is short of capacity rather than broken, which points at airflow, seal or condenser rather than at the compressor.
- The cabinet is cold but the load has gone soft — Ice cream and soft fruit give way first because they sit closest to the safe-storage threshold.
Causes, most likely first on the ACFM line
- Lid or door seal not closing — It ranks first here because it is the only cause that both explains continuous running and produces the frost pattern owners describe, and it costs nothing to test.
- Frost blanket on the cold surface — Ranked second on this roster: manual-defrost cabinets reach this state routinely and the fix is a defrost rather than a part, which is why it is worth ruling in early.
- Condenser dirty or the cabinet boxed in — Ranked third on this roster: heat has to leave the cabinet somewhere, and a condenser choked with dust or a cabinet pushed tight against a wall gives it nowhere to go, so the machine runs continuously and still loses ground.
- Loss in the sealed system — It ranks last because every cause above it is more common and cheaper to put right, and because getting here first is how owners end up replacing a working cabinet.
- Body: The ranking here keeps the brand-generic order, and what the ACFM 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.
- Close the lid or door on a strip of paper and pull — Do it at several points around the opening. Anywhere the paper slides out freely is a leak, and that is where the frost will be.
- Look at the cold surface and measure the build-up by eye — A layer thick enough to hide the surface underneath is enough to explain the complaint on its own. Defrost fully and see whether the cabinet recovers.
- Clear the condenser and give the cabinet air on every side — With the power off, clean the coil or compartment and pull the cabinet clear of the wall. Then give it a day before judging.
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 use a sharp tool to break frost off a cold surface: the tubing behind it is thin-walled, and a nicked tube turns a defrost into a replacement. A freezer holds food safely at 0 °F (−18 °C) or below, so move the load to a cooler with ice before you start rather than after.

When to call a technician
The owner side of this fault ends at the point a panel has to come off. Defrosting, re-seating a seal, clearing the condenser and giving the cabinet air are all yours and cost nothing. Anything behind a fastener, anything involving the control sensor, and everything on the sealed circuit is a service call.
