The short answer
An ice maker that has stopped is far more often a water-supply or a temperature problem than a broken ice maker. On a compact cabinet the ranking below starts with the supply side because that is where the fault usually is and because it costs nothing to check.
What you observe
- The tray is empty and stays empty — Nothing is arriving, which points at the supply side rather than the mechanism.
- Small, hollow or partly formed cubes — Water is arriving but not enough of it, which is a restriction rather than a stoppage.
- NEAR MISS: cubes fused into one block in the bin — That is melt and refreeze from a door left ajar or a warm spell, not an ice-maker fault.
Causes, most likely first on this cabinet
- The shutoff arm or switch is in the off position — A wire arm knocked up by a bag of ice, or a switch left off after cleaning, stops the whole system silently. Ranked first on Danby Deisgner: a compact cabinet has little of everything - little thermal mass, a shallow condenser, a small drain and almost no clearance - so the first thing to go wrong is nearly always whatever its installation is asking too much of, and on the line whose plate is frequently mis-keyed, an owner working from the wrong manual compounds the original fault.
- A water filter at the end of its life — A clogged filter restricts flow enough to make small or hollow cubes long before it stops them entirely, and it is the most common cause of bad ice rather than no ice. Ranked second: it ranks here because it is common enough to be worth checking, but only once the free checks above are clean.
- The freezer section is not cold enough — Ice production stops when the compartment cannot reach its set point. Ranked third: it is in the middle of the list because it is cheap to rule out and expensive to assume.
- The ice maker module itself — The motor, the thermostat or the harvest mechanism inside the assembly. Ranked last: it is last because on an appliance this size the major components outlive everything around them, and replacing one often costs more than the appliance is worth.
Check in this order, and why
- Look at the shutoff arm or the control switch — Arm down, or switch on, is the position that allows production.
- Check how long the filter has been in — A filter past its interval explains small cubes, slow dispensing and off-tasting ice all at once.
- Check whether the freezer itself is up to temperature — Soft ice cream and a slow-freezing tray of water tell you this is a cooling fault and not an ice fault.
What an owner can safely check
- Set the shutoff arm down or switch the ice maker on and wait — Give it several hours before judging, because a cold start takes a full cycle or two to produce the first tray.
About 5 min
- Replace the water filter and flush the line — Fit the correct filter for the cabinet, then run water through until it is clear before judging the ice.
About 20 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before reaching behind the rear panel or removing the ice maker cover, and leave it off while your hands are inside: a capacitor can hold a charge after the power is off and a harvest arm can move under power. Turn the water supply off before you disturb any fitting, and do not use a metal tool or a heat gun to clear ice from inside the cabinet.
When to call a technician
Call once the supply side, the filter and the freezer temperature have all been ruled out, because what is left is inside the assembly. Call sooner if you find water where it should not be, if the fill tube refreezes within days of being cleared, or if the freezer section itself is not holding temperature.

What this page does not cover
This page covers Danby Deisgner as a family, not one model line. Where a page exists for the line named on your plate it is linked below and it is the more precise answer. Not here: the filter part number, the ice maker assembly number and the fill timing for your specific cabinet, all of which are model-specific.
