The short answer
This page covers a single model, so every unit in service is the same machine. That is why, on the BC models, this complaint comes back to a condenser coil blanketed in dust and lint before anything else — and why the order below departs from the brand-generic one.
What you observe
- Frost builds as a sheet on the back wall of the freezer — Not the usual light dusting — a solid skin you can knock with a knuckle.
- The freezer still holds while the fresh-food side climbs — A split like this narrows the list sharply, because it points at airflow between compartments rather than at cooling itself.
- The compressor never seems to stop — It runs and runs without reaching temperature, which is the same fault seen from the other side.
- Condensation or a damp smell inside the fresh-food compartment — Warm air is reaching the cabinet, and it carries moisture with it.
- NEAR MISS — the cabinet is cold but water is pooling under the crisper — That is a drain fault, not a cooling fault, and it is covered on the leak page for this appliance.
Causes, most likely first on the BC line
- A condenser coil blanketed in dust and lint — Ranked first here — it costs nothing to rule out and it is the cause most often found on a cabinet nobody has pulled out in years.
- A cabinet standing somewhere it cannot shed heat — Second here — it is free to correct and it makes every other cause worse.
- A compressor start relay or overload that has given up — Third here — it usually announces itself with a repeated click rather than with a quietly warming cabinet.
- Body: With one model in scope there is no spread of builds to hedge against, so a design-inherent fault ranks above an age-related one and the list below says so plainly. The visible effect is that a cabinet standing somewhere it cannot shed heat takes a place that a compressor start relay or overload would otherwise hold.
Check in this order, and why
- Pull the cabinet out and look at the coil at the back or behind the toe grille — A grey felt across the fins is the answer; a coil you can see the metal of is not.
- Look at what is around and above the cabinet — Against a radiator, boxed into a cupboard, or with the top packed to the ceiling — all three hold heat against the condenser.
- Listen at the compressor for a click every few minutes with no run that follows — A click-and-silence pattern is the start circuit; a steady hum is not.
- Body: One model means one layout, so the order below is the order of the panels you would open, and there is no second build to hedge against. The checks below are in the same order as the causes above them, so a clean result sends you one step further down rather than back to the top.
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. Do not chip ice off an evaporator with anything metal: the tubing behind it is thin-walled, and a puncture turns a cheap repair into a sealed-system job.
Models in the BC family — Every model this page covers, exactly as the model line is recorded. Nothing outside this table is a model number, and nothing on this page claims to cover a model that is not in it.

When to call a technician
Call once the owner checks above come back clean, and call at once if the fault is on the sealed system — refrigerant work is licensed work and the tools for it are not owner tools. Oil at the compressor, or a burning smell from the back of the cabinet, is a stop-now condition: every hour it runs after that costs more to put right.
