The short answer
On a Danby refrigerator, why there is no ice, or bad ice comes down to a short list, and on this line the order is not the generic one. The diagnosis starts at ice fusing because it is not being used, because cubes sublimate and re-freeze into a block when the bin sits untouched, and that is a usage pattern rather than a fault. The first three checks below need no tools and no parts; the point at which this stops being an owner job is stated further down, as a condition rather than as a recommendation.
What you are seeing
- The bin is empty and the ice maker has not cycled in days.
- Ice cubes are small, hollow, or fused into one lump.
- Ice tastes or smells of whatever was last stored uncovered in the freezer.
- The ice maker cycles, dumps and fills, but the water freezes in the fill tube instead of the mould.
- Water pools in the mould and never freezes, or overflows the mould.
- Ice forms as a slab across the bin rather than as separate cubes.
- Note: Near-miss symptoms that mean a different fault: If the whole freezer is not making cold, the ice maker is a symptom — read the cooling page instead. If water is on the floor rather than in the bin, that is the leak page. If the cabinet has no ice maker at all, the complaint is usually frost on the freezer wall, which is a defrost question.
Causes, ranked for a Danby refrigerator
- Ice fusing because it is not being used — Why this rank: Cubes sublimate and re-freeze into a block when the bin sits untouched, and that is a usage pattern rather than a fault.
- A freezer that is not cold enough to trigger a harvest — Why this rank: The mould thermostat will not release ice until the mould is cold enough, so a marginal freezer produces no ice at all rather than slow ice.
- The wrong platform assumed at the start of the diagnosis — Why this rank: The Danby badge covers several unrelated platforms, so a large share of wrong turns here begin with a manual-defrost cabinet being treated as a frost-free one, or a portable machine as a plumbed-in one.
- A frozen fill tube — Why this rank: The tube is the coldest point in the water path, so it is where a slow fill or a slightly warm supply first turns to ice.
- The bail arm or the shut-off left in the off position — Why this rank: It is free to check, it is knocked up by a bag of frozen food, and it stops the ice maker as completely as any failure.
- Odour transfer from uncovered food or an old filter — Why this rank: Ice is a sponge for freezer air, so taste complaints are almost never about the ice maker itself.
What to check, in order
- Confirm the bail arm or the shut-off is in the on position and nothing is holding it up. — Order: First — Why: It is the cheapest cause on the list and it accounts for a striking share of no-ice calls.
- Put a thermometer in the freezer and confirm it is holding 0 °F (−18 °C) or below. — Order: Second — Why: A freezer above that will not harvest, and no work on the ice maker will change that until the temperature is fixed.
- Look at the fill tube where it enters the ice maker for a plug of ice. — Order: Third — Why: It is visible without tools and it explains a mould that never fills while the valve is working perfectly.
- Force a harvest with the manual test the manual gives, and listen for the valve buzzing as the mould fills. — Order: Fourth — Why: It exercises the whole circuit in one cycle and tells you which stage stops.
Steps a homeowner can take
- Unplug the appliance or switch off its breaker before removing the ice maker or any panel. — Tools: none — Time: a moment
- Check the bail arm or the shut-off, and clear any stored food that is holding it up. — Tools: none — Time: a moment
- Put a thermometer in the freezer, close the door and read it after several hours. — Tools: thermometer — Time: overnight
- Empty the bin completely and discard fused ice, then leave the bin out for a cycle and watch what the ice maker does. — Tools: none — Time: half an hour or so
- Melt a frozen fill tube with a hair dryer on low, keeping the heat moving and away from any plastic. — Tools: hair dryer, towels — Time: half an hour or so
- Replace the water filter with the correct part and seat it fully, then run and discard several batches of ice. — Tools: replacement filter — Time: half an hour or so
Before you start
Safety
Unplug the appliance or switch off its breaker before removing the ice maker or any panel. A capacitor can hold a charge after the power is off. Never use a knife, a screwdriver or a pick to break ice out of a mould or a bin — the mould heater and the water tubing are directly behind the ice. Shut the water supply off at the valve before disturbing any fitting.
When this stops being an owner job
Call when the freezer holds 0 °F (−18 °C), the bail arm is on, the fill tube is clear and the mould still does not fill, or when the mould fills and never harvests. Testing a valve and a mould heater means metering a live circuit, and that is where the homeowner part of this stops.

Generalized information
This page is generalized: it covers Danby across a whole refrigerator range rather than one family or one model, and where a more specific page exists it is linked here. It does not cover the Danby Designer, Danby Premiere and Danby One Plug sub-lines and their model-level pages, and it does not carry serial-range or model-group detail — check the rating plate before ordering any part. It is the compact and manual-defrost half of the Danby refrigerator range; the frost-free Danby cabinets are covered separately and linked above.
