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
- Cubes that taste or smell wrong — Old ice absorbing cabinet odours, or a filter well past its service life.
- The ice maker cycles but drops nothing — The harvest is running dry, which again points upstream at the fill.
- 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 Designer: 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 a finished cabinet fitted into a surround loses the clearance the specification assumed.
- Water is not reaching the cabinet — A closed saddle valve, a kinked line behind the cabinet or a supply shut off during other work. Ranked second: it ranks below the causes above because it costs more effort, not because it is rare.
- 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 third: it sits here because it produces the same complaint as the cause above it and takes longer to confirm.
- 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.
- Trace the line from the tap to the back of the cabinet — Look for a closed valve and a kink where the cabinet was last pushed back.
- 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.
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
- Check the supply valve and straighten the line behind the cabinet — Open the valve fully, take the kink out and leave a gentle loop so the line is not strained when the cabinet goes back.
About 15 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 the Danby Designer refrigerator as a class, not one model or production run. Any family- or model-specific page for your unit takes precedence over it. 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.
