The answer first
On the BC family, a cabinet that runs but will not hold temperature usually comes down to condenser coil blocked. Start with one thing: feel the back or the side panel while the unit is running.
What the owner actually sees
- The cabinet is warm and the unit is clearly running — You can hear the compressor working, but the air inside never gets properly cold and food in the door warms first.
- The compressor runs and never cycles off — A healthy unit stops for a while once it reaches temperature.
- A sheet of frost on the freezer rear wall — Not the light dusting that comes and goes, but a solid white sheet that grows back within a day of being scraped off.
- NEAR MISS: it cools but makes a loud new noise — If the cold is still there and the noise is what changed, read the noise and vibration page for this line instead.
The ranking, and why it is this one
- Condenser coil blocked, or starved of clearance — It ranks high here because it is the one cause the owner creates and the owner can undo: a cabinet pushed back against a wall, into a cupboard, or against a heat source loses its ability to dump heat.
- Door seal letting warm air in — On the smaller cabinets in this class the door is most of the front, so a seal that has gone hard or a hinge that has dropped costs a much larger share of the total cold.
- Stalled defrost, with the evaporator iced over — It ranks here because the failure is gradual: the defrost cycle weakens long before it stops, the evaporator collects ice over weeks, and the owner notices a warm cabinet rather than the ice that caused it.
- Sealed system or compressor fault — A sealed-system fault is the one outcome on this page that is not an owner fix at any stage: the refrigerant circuit is closed, licensed work, and nothing on it is a home check.
- Body: The prefix this family uses marks a single-compartment cooler rather than a combination cabinet, so there is no separate freezer space, no air being moved between two compartments, and no defrost cycle of the kind a two-door cabinet runs. Where that departs from the brand-generic order is condenser coil blocked, which moves up on these models because there is no fan moving air between two compartments here, so heat rejection at the cabinet wall and the door seal carry more of the load than they would on a two-door unit.
What to check first, second, third
- Feel the back or the side panel while the unit is running — Warm is right; scorching, with no clearance behind and a dusty coil, is the answer.
- Close the door on a strip of paper and pull it out — Do it at several points around the frame.
- Look at the freezer rear panel for a frost sheet — A solid sheet where the cold air leaves the freezer confirms the airflow path is blocked before any tool comes out.
- Body: The order follows the ranking above rather than the layout of the cabinet: each check either confirms the cause above it or removes it, and they are arranged so that the free checks come before anything that needs the unit moved or a panel off. With one configuration in the field, there is no variant that reorders these.
Safety first
Safety
Switch the power off at the breaker or pull the plug before any panel comes off, and keep it off for the whole job rather than switching back to test. There is mains voltage at the compressor terminals and at the start relay, and a capacitor there can stay charged with the cord in your hand.

Where the owner checks end
The line is the panel. Everything in front of it, cleaning, seals, clearance, settings and a manual defrost, is yours.
