What this usually is
On the BD models this complaint is most often a defrost cycle that stops completing rather than anything deeper. This page covers a single model, so every unit in service is the same machine. The order below is settled by how this line is built, not by what is true of the brand as a whole.
What the owner actually sees
- Ice cream has gone soft but frozen food is still solid — A freezer a few degrees warm reads exactly like this before anything thaws.
- 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 unit is silent and nothing is cold — That is a no-power or start-circuit fault, and it belongs on a different page.
What it usually turns out to be, in order on the BD line
- A defrost cycle that stops completing — Ranked first here — it produces exactly this complaint — a running unit and a warm cabinet — while every other symptom stays normal for weeks.
- A leak or restriction in the sealed system — Second here — it is the least likely of the list and the only one that is not an owner check.
- A cabinet standing somewhere it cannot shed heat — Third here — it is free to correct and it makes every other cause worse.
- A compressor start relay or overload that has given up — Fourth 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. Against a ranking that ignored how these are built, a leak or restriction in the sealed system moves up and a compressor start relay or overload moves down — that is the whole departure.
What to look at first, second, third
- Empty the freezer, leave the door open and let the cabinet stand warm overnight — If cold returns afterwards and then fades again over days, the defrost system is the cause and nothing else needs testing.
- Leave this one to a technician — It is confirmed with gauges on a system that must then be recovered and recharged, which is licensed work.
- 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. Each check answers the cause above it, in the same order, so a clean result moves you down the list rather than sideways.
Switch it off first
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Leave the door switch wired as it is, and never run the cabinet with a panel off to watch it work.

Where owner work stops
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.
