The short answer
A freezer that is running while its contents soften is almost always losing the argument with warm humid air rather than losing its refrigerant: the lid or door, the frost load, or the air it has to dump its heat into. On these models the two CL rows differ by one capacity digit and nothing else. All three of those are owner-checkable, and the sealed system is the last thing to suspect rather than the first.
What you observe
- Contents softening while the unit runs continuously — Cold is being made and is not keeping up, which is what separates this from a dead unit.
- Heavy frost building far faster than it used to — Humid air is getting in, and each new layer of frost makes the next one easier.
- The lid or door needs a hard push to close — A seal fighting frost build-up, and the cause of the symptom above it.
- The cabinet sides are hot to the touch — The unit cannot dump its heat, which is a clearance or a dust question.
- NEAR MISS — silent with nothing cold at all — That is a power or control fault rather than a cooling one, and this page does not cover it.
Causes, most likely first on the CL models
- Lid or door seal and closure — First on these models. A seal held open by frost, by a packed load or by a hinge that has dropped lets humid air in constantly, and a freezer loses that argument faster than a refrigerator does.
- Frost load inside the cabinet — Second, and it follows directly from the first. Frost on the walls is an insulating layer between the contents and the cold surface, so the unit runs longer to achieve less.
- Clearance and condenser dust — Third. A unit in a garage corner or against a wall has nowhere to put its heat, and dust on the coil has exactly the same effect as no clearance at all.
- Ambient temperature and loading — Fourth. A large warm load put in at once, or a unit standing somewhere very hot, gives a cabinet that never catches up through no fault of its own.
- Sealed system or compressor — Last, and the only one on the list that is licensed work rather than owner work. No counted corpus covers these models, so this ranks mechanisms rather than measured shares.
Check in this order, and why
- Read the digits on the plate before you judge anything by feel — The two rows in the table differ in size, and a bigger cabinet takes longer to recover from the same fault, so the size decides how patient to be with every later step.
- Check the seal with a sheet of paper right round — Anywhere it pulls out freely is where the warm air is arriving, and it is the top cause here.
- Judge how much frost has built and when it last defrosted — A freezer holds food safely at 0 °F (−18 °C) or below, and heavy frost is what stops it getting there.
- Clear space around the cabinet and clean the coil — Both sides and the back need air. Dust is an insulator and a corner is not clearance.
- Defrost it fully, then judge it again over a day — A unit that holds temperature after a full defrost has named its own fault.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never chip frost off with a knife or a screwdriver: the walls of a freezer carry tubing directly behind them and a puncture ends the appliance. Do not put a heat gun or a naked flame near the liner, and do not stand in melt water with the unit plugged in.

When to call a technician
Call when the seal passes, the frost is gone, the coil is clean and the clearance is right and the contents still soften, because what is left is the sealed side. Call sooner if the cabinet frosts heavily again within days of a full defrost, which points at a seal or a control rather than a habit. Call at once if you see oil where the tubing runs, because that means the system is open. Say which of the two sizes you have when you call, because the larger cabinet changes how long a result takes to read.
