The short answer for this family
On the Criterion BCD refrigerator family a cabinet that runs without holding temperature is an airflow and heat-rejection problem far more often than a dead compressor, because an evaporator behind the rear panel of the lower freezer compartment is what this platform puts in the cold path. Only the last of the ranked causes below is outside owner territory. The table below lists the six models this profile covers.
What owners of these models actually see
- The cabinet is warm and the compressor is clearly running — You hear the compressor and the cabinet still drifts up. That combination points into the cold path, not at the compressor.
- Food at the front is soft while food at the back is hard — A split across the shelves says cold is being made but not distributed, which here is the duct carrying cold up from the lower evaporator.
- One compartment is wrong and the other is close to correct — On a bottom-freezer cabinet a warm fresh-food compartment over a still-frozen drawer points at the duct and the damper feeding upward, not at the compressor.
- NEAR MISS: the cabinet is silent and nothing runs at all — Silence is a power, start-relay or control fault, diagnosed in a different order. Start there instead of here.
Ranked causes for this family
- A defrost cycle that has stalled rather than failed outright — First wherever this family is frost-free: automatic, and the drain trough that carries the melt sits directly above the freezer floor, which is where this platform typically shows its faults. Ice builds over weeks, so the owner meets a warm cabinet rather than a frozen evaporator.
- The evaporator fan has failed or is being stopped by ice — Second, because cold is ducted up from the lower evaporator into the fresh-food compartment, so a blocked duct starves the compartment the owner uses most. A stopped fan gives a warm cabinet without the frost sheet the defrost fault leaves behind, and that is what separates the two.
- Blocked condenser airflow or a dirty condenser coil — Ranked here by how this cabinet breathes: the condenser sits at the back or underneath and needs clear air on both sides of it. Heat that cannot leave comes back as a cabinet that will not pull down.
- A door or lid seal that is holding the cabinet open — This platform carries a tall upper gasket plus a drawer gasket that seals on three or four sides rather than around a door. A drawer gasket seals on three or four sides rather than around a door, and a drawer loaded past its rail line holds it open without looking open.
The checking order on these models
- Confirm the cabinet is actually running — Listen at the back for the compressor and feel the condenser for heat. A cabinet not running at all is a different page. Confirm your own model against the table first.
- Look at the cold surface for a frost blanket — Open up and look at the rear panel of the lower freezer compartment. Frost turned into a solid sheet is the cause, not a side effect, and it decides everything after it.
- Listen for the evaporator fan with the door held closed by hand — Press the door switch in and listen. A silent fan and a frosted coil point at different causes and want different parts.
Before any panel comes off
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 tape the door switch shut and walk away, and do not open, cut or braze any part of the sealed refrigerant circuit: that is licensed work. A refrigerator holds food safely at 40 °F (4 °C) or below and a freezer at 0 °F (-18 °C) or below, so move perishable food out while you work.

When to call a technician
Where the line falls here is worth stating plainly. Call once the airflow checks are clean, because what is left on this family is the sealed system and the control board, and neither is an owner part. Call immediately for a burning smell, oil around the compressor, or a compressor that tries to start and cuts out every few minutes: oil outside the tubing means the circuit is open. On this platform the cabinet has to come away from the wall before most work can start, which is a two-person job on a loaded cabinet.
