Start here
The useful split on these models is between a cabinet that is slightly too warm and one that is not cooling at all. Slightly warm points at airflow, door seal, loading or ambient heat. Not cooling at all points at the evaporator being iced over, a fan that has stopped, or the sealed system. The BCD designation spans five model numbers in the table below. Which one you have decides the part number, not the repair — the fault below is the same across the line.
What you actually observe
- Cold at the back of a shelf, warm at the front — Air is arriving but not circulating. Usually a cabinet packed against its vents.
- Compressor runs for hours without a break — A unit that never satisfies its thermostat is losing heat-rejection capacity somewhere.
- Cabinet recovers overnight and warms during the day — The pattern of a unit that is marginal rather than broken — ambient, coil or seal.
- Condenser area thick with dust or pet hair — A finding, not a symptom, but it explains more warm cabinets than any single part.
- NEAR MISS — only one shelf is warm — That is circulation or a door being opened often, not a failure of the cooling system.
Ranked causes on these models
- Evaporator frost blocking the air path — Ranked first when the unit runs constantly and the back wall inside is iced. The cabinet warms precisely because the system is working — the cold has nowhere to go.
- Dirty condenser or no clearance behind — Second and the commonest maintenance failure on these cabinets. It is free to fix and it is checked before any part is considered.
- Door seal and gasket — Third. Close the door on a strip of paper and pull: if it slides out freely anywhere along the edge, the seal is not doing its job at that point.
- Start relay or compressor — Last. A relay clicking every few minutes with no cooling is the classic pattern, and it is a small part behind a cover that owners should still leave to a technician.
Check in this order, and why that order
- Separate never-cooled from getting-warmer — Gradual loss points at the coil, the seal or the room. Sudden total loss points at a fan, a frosted evaporator or the sealed system.
- Feel the condenser and the sides — A coil that is stone cold while the compressor hums suggests the system is not pumping; a coil that is hot suggests it is working and cannot shed heat.
- Unload and re-space the cabinet — Blocked internal vents are invisible until the shelves come out, and on small cabinets they are a common cause of uneven warmth.
- Then hand it over — Everything left — fan motors, defrost components, relay, sealed system — is measured rather than inspected, and on a live cabinet that is service work.
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. Treat a heavy cabinet as a two-person move — sliding one out over a tiled floor on your own is how doors get twisted and feet get broken. A refrigerator holds food safely at 40 °F (4 °C) or below, so deal with the food before the fault, and never use a heat gun or a knife to clear ice from an evaporator.

Where the owner line is on these models
The owner line on these models sits at the back panel. Coil cleaning, clearance, the door seal, the internal vents, the thermostat setting and the load are yours, and between them they explain most warm cabinets. Call when the coil is clean and the cabinet is still warm, when the compressor hums without cooling, when a relay clicks repeatedly, or when the evaporator ices up again within days of being defrosted. Anything involving refrigerant is licensed work, and on a compact cabinet it is also the point at which replacement usually wins on cost. A technician will ask which of the five BCD models you have before they set off, and the rating plate inside the cabinet is where that number lives.
