The short answer
Start here. On this refrigerator, a cycle of days is the signature of a defrost problem, because that is roughly how long frost takes to bridge an evaporator. A full manual defrost is the test and the temporary fix; if cooling returns and then fails again on the same schedule, the defrost system is the answer and that is a service call.
What you actually see
- Food spoils faster than it used to — Milk turns a day or two early and salad greens wilt, which is the earliest honest sign that the cabinet has drifted warm.
- The compressor runs constantly — A hum that never stops means the machine is asking for cold it cannot make, not that it is working hard.
- The back wall inside is frosted solid — A sheet of ice on the inner rear panel blocks the airflow that is supposed to carry cold forward.
Causes, ranked for this refrigerator
- Defrost system not clearing the evaporator — Top of the list: a unit that cools well for a week and then warms over a day or two is describing a defrost failure rather than a compressor failure. Getting a definite answer here is worth more than a quick look at the three below it.
- Evaporator fan not moving air — Next: on a two-compartment unit the fan is what carries cold from where it is made to where you keep food, so a stalled fan reads exactly like lost cooling. If this is the answer, the rest of the list stops mattering entirely.
- Door seal not closing the cabinet — Then: warm humid air coming in never stops, so the unit never catches up and the symptom reads as lost cooling rather than as a door problem. Where this checks out clean, treat the next entry as the working theory rather than a possibility.
What to check, in order
- First — the evaporator for frost — Look at the inner rear panel of the freezer section. A smooth white sheet rather than light frost means the defrost cycle is not clearing it.
- Second — the evaporator fan — Listen at the fresh-food vents. Silence with the compressor running is a fan problem, not a compressor problem.
Checks an owner can do safely
- Step 1. Put a thermometer in the cabinet and leave it — A glass of water on the middle shelf with a thermometer in it, left for several hours, tells you the real cabinet temperature rather than the door-open temperature. A refrigerator holds food safely at 40 °F (4 °C) or below.
Tools: fridge thermometer, glass of waterAbout 20 min
- Step 2. Test the door seal with a sheet of paper — Shut the door on a sheet of paper and pull it out. Repeat every hand-width around the frame. Free-sliding paper marks the spot where room air is getting in.
Tools: sheet of paperAbout 10 min
- Step 3. Confirm the internal fan runs — Hold the door switch in with a finger and listen. The fan should be audible within a second or two. Silence with the compressor running points at the fan.

Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. The cooling circuit is sealed and under pressure: do not cut, bend, kink or unbraze any tubing, and do not attempt to add or recover refrigerant — that is licensed work and the tubing is not repairable with hand tools.
When this becomes a service call
The line is not about confidence, it is about what the next step needs. The moment the next step would be measuring a winding, discharging a capacitor or touching the refrigerant tubing, stop; those are licensed or trained tasks and the machine has to be running for them.

What this page does not cover
This is the general page. It applies to Black+Decker refrigerators broadly and deliberately avoids anything that would only be true of one family or one production run — board revisions, part numbers, code tables and torque figures all belong a level down. Where such a page exists it takes precedence over this one, and Related pages is where to find it.
