The short answer
The short answer for a Black+Decker freezer: no ice is usually no permission or no water rather than a broken maker. The first three checks are free and cover most of these; a module that fills and never harvests is the part that ends owner work.
What you actually see
- No ice at all after a full day — A machine that has produced nothing in a day has a hard stop rather than a slow one.
- Ice in the bin fused into a solid block — A block is melt and refreeze, which means the compartment warmed between runs.
- A sheet of ice on the compartment floor under the bin — Overfill puts water where cubes should not be.
Causes, ranked for this freezer
- Ice maker switched off or the arm parked — Most likely — every maker has an off position, and it is the single most common reason one stops — especially after the cabinet has been moved or defrosted. If this is the answer, the rest of the list stops mattering entirely.
- No water reaching the fill valve — Common — no water explains every no-ice complaint at once and costs nothing to check, which is why it sits near the top. Where this checks out clean, treat the next entry as the working theory rather than a possibility.
- Compartment not cold enough to harvest — Regular — a harvest cycle waits for the mould to reach temperature, so a compartment running warm makes no ice at all rather than making it slowly. A clean result here does not just remove one part; it removes everything that depends on it.
What to check, in order
- First — the on/off arm or switch — Empty the bin completely and check the arm swings through its full travel.
- Second — the supply line and shut-off — Follow the line from the cabinet back to the shut-off and confirm the valve is fully open rather than cracked open.
Checks an owner can do safely
- Step 1. Measure the compartment temperature — Leave a thermometer between packages for several hours. A freezer holds food safely at 0 °F (−18 °C) or below, and a harvest cycle needs that cold.

- Step 2. Check the supply valve and line — Follow the line back to the shut-off, open it fully, and straighten any kink behind the cabinet.

- Step 3. Listen during a fill attempt — A buzz at the back with no water arriving means the valve is energized and not passing water.

Safety
Two isolations, not one: power at the plug or breaker, water at the supply valve. A capacitor can hold a charge after the power is off. Standing water under an energized appliance is an electrical hazard first and a plumbing problem second.
When this becomes a service call
Draw the line by the tool the next step requires, not by how the freezer looks. If the ice fault turns out to be a compartment that cannot hold temperature, the not-freezing checks are the right page and the maker will recover on its own.

It names the fault, ranks the causes and gives the order to check them, and it deliberately does not name a board revision, a part number or a model-specific tolerance.
