The short answer
Here is what the symptom means on a Black+Decker refrigerator: a clean stop with no warning points at the start circuit or the control rather than at the gradual causes that warm a cabinet over weeks. The owner checks here are short and mostly about listening; a click-and-pause pattern at the back ends them.
What you actually see
- The cabinet is cool but not cold — Drinks are drinkable, butter is soft, and the thermometer sits above 40 °F (4 °C) no matter where the dial is set.
- The compressor never runs at all — Silence at the back, a light that still comes on, and a cabinet slowly matching the room.
- The freezer section stays cold, the fresh-food section does not — A split like this points at air movement between the two compartments rather than at cooling capacity.
Causes, ranked for this refrigerator
- Start relay or overload protector failed — Ranks first because when the compressor tries to start and cannot, the overload cuts it out, and the pattern is a click every few minutes with no run. This is the entry most often blamed correctly and diagnosed carelessly, so take the extra minute.
- Thermostat or temperature sensor out of calibration — Second because the control on these is simple, which is a virtue until it drifts — the dial then means something different from what it says. Confirm it before moving on, because the entries below read differently once it is ruled out.
- Sealed system failure — Third because it is genuinely last, because everything above it fails more often and is cheaper to confirm; a sealed fault is what remains after they are ruled out. Rule it in or out properly here; a maybe at this position costs an hour further down.
What to check, in order
- First — the compressor start components — Note whether anything at the back is warm after an hour. A cold compressor body with a live cabinet means it never ran.
- Second — the thermostat setting and sensor — Set the dial to its coldest position and leave it a full day with a thermometer in a glass of water on the middle shelf.
Checks an owner can do safely
- Step 1. Listen at the back for a start-and-cut-out pattern — Stand behind the unit for several minutes. A click, silence, then another click is the overload cycling on a compressor that will not start, and that is where owner checks end.
Tools: noneAbout 15 min
- Step 2. 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 3. Clean the condenser coil — Unplug the unit. Brush and vacuum the coil at the back or under the base until you can see the fins. Do not bend them; a soft brush and a nozzle are enough.

Safety
Pull the plug or trip the breaker first. A capacitor can hold a charge after the power is off. Treat the sealed system as off limits: the tubing carries pressure, the compressor terminals carry a stored charge, and neither is diagnosed by opening it.
When this becomes a service call
The line is not about confidence, it is about what the next step needs. If the coil is clean, the seals hold, the fans run and the frost pattern is normal, the remaining candidates all need a meter or a gauge set on a running machine — that is service work.

What this page does not cover
One limitation worth stating up front: this page is written for the Black+Decker refrigerator range rather than for your particular unit. It does not name families, model numbers or control revisions. Where a page exists that does, it is more precise than this one and it is linked under Related pages.
