The short answer
A Black+Decker refrigerator showing this usually tells you one thing: water arriving with nothing harvesting points at the compartment temperature first and the module second. Confirming the compartment is genuinely cold is free; past that, the module is a part swap with a harness behind it.
What you actually see
- No ice at all after a full day — A machine that has made nothing in a day has either no water, no cold or no permission to run.
- Hollow or partly formed cubes — Half-filled cubes point at fill volume rather than at freezing.
- The ice maker fills but never harvests — Water goes in, the mould stays full, and nothing drops into the bin.
Causes, ranked for this refrigerator
- Freezer compartment not cold enough to harvest — The usual answer. a harvest cycle waits for the mould to reach temperature, so a freezer section running warm makes no ice at all rather than making it slowly. Rule it in or out properly here; a maybe at this position costs an hour further down.
- Ice maker module failed — The runner-up. a module that fills and never harvests is the one pattern that points here directly rather than by elimination. Getting a definite answer here is worth more than a quick look at the three below it.
- Fill tube frozen shut — Third. a slow drip after a fill freezes in the tube and builds until the next fill cannot get through, which stops production with everything else working. If this is the answer, the rest of the list stops mattering entirely.
What to check, in order
- First — the freezer temperature — Look at whether existing ice in the bin has fused into a block. Fusing means the compartment is warming between compressor runs.
- Second — nothing — this is what is left — There is no owner test beyond the pattern: water arrives, the mould stays full, and nothing ever drops.
Checks an owner can do safely
- Step 1. Look for ice in the fill tube — Shine a light on the small tube that feeds the mould. Clear any plug of ice with a warm damp cloth, never with a tool.

- Step 2. Listen for the fill valve during a cycle — A buzz at the back with no water arriving means the valve is being energized and is not passing water.
Tools: noneAbout 10 min
- Step 3. Confirm the ice maker is switched on — Check the wire arm or switch is in the run position and nothing in the bin is holding the arm up. This is the most common single answer.

Safety
Shut off, unplug, dry off — in that order. A capacitor can hold a charge after the power is off. Kneeling on a wet floor beside a plugged-in appliance is the one mistake on this page that has consequences beyond the repair.
When this becomes a service call
The line is not about confidence, it is about what the next step needs. If the ice fault turns out to be a freezer section that will not hold temperature, the cooling checks are the right page and the ice maker will recover on its own once they are done.

What this page does not cover
Treat what follows as the class-level answer for a Black+Decker refrigerator. It will not tell you which board your unit has, which part number fits it, or what a particular code means on a particular family, because those differ within the range. The family and model pages beneath this one carry that, and they are linked under Related pages.
