The answer first
An ice maker that has stopped is almost always a water problem rather than a broken ice maker. On this machine the first suspect is inlet valve not opening.
What you observe
- The bin is empty and the maker is silent — No cycle is being attempted, which points at a switch, an arm or a sensor.
- Cubes are small, hollow or half-formed — Water is arriving but not enough of it — a restriction rather than a stoppage.
- A thin sheet of ice across the bottom of the bin — Water reached the mould and overflowed, which is a fill or a level problem.
- NEAR MISS — no ice and the freezer is not properly cold — Fix the cooling first; the ice maker is a symptom and the cooling-failure page is the right one.
Causes, most likely first on a Sharp refrigerator
- Inlet valve not opening — The valve is electrically opened for a few seconds per cycle; when it fails, the maker cycles dry. Ranked first on a Sharp refrigerator: a maker that cycles and drops nothing has been given no water, and this is where the water stops.
- Water filter clogged, overdue or not seated — A filter at the end of its life passes enough water for a slow glass and not enough for an ice mould.
- Fill tube frozen — The short tube that carries water into the mould can freeze solid, so each cycle adds a little more ice.
- Freezer not cold enough to trigger a harvest — The mould must reach its harvest temperature before cubes are ejected, and a marginal freezer never gets there.
Check in this order, and why
- Listen for a short buzz and a fill sound at the back during a cycle — A buzz with no water means the valve is energised and blocked rather than dead.
- Take the filter out and run the dispenser with the bypass in place, if the machine has one — Reseat the cartridge firmly: a partial seat behaves exactly like a blockage.
- Look at the fill tube where it enters the mould for a plug of ice — A visible plug is the diagnosis and warm air is the cure.
What an owner can safely check
- Remove the filter, reseat it firmly, and run several litres through the dispenser to purge air — If flow improves with the filter out, fit a new cartridge — the old one is the restriction.
Tools: jugAbout 20 min
- Clear the fill tube with warm air or a cloth soaked in warm water, never with anything sharp — Warm the tube until the plug melts and the water runs into the mould rather than over it.
Tools: hairdryer on low, warm clothAbout 25 min
- STOP HERE if the next check needs a panel off or a meter on live terminals — That is where the owner checks end and a service call begins, whatever the ranking says.
Before you open anything
Safety
Unplug the refrigerator or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Leave the door switch wired as you found it. Never take a knife, a screwdriver or a heat gun to frost on an evaporator: the tubing behind it is thin, pressurised, and a puncture ends the appliance. Empty a loaded cabinet before you move it.
When to call a technician
Call once the supply, the filter, the arm and the fill tube are all clear and the mould is still empty, because what is left is the inlet valve or the module and both are behind fixed panels. Call sooner if you find water anywhere outside the cabinet. Sharp parts are generally obtainable through appliance parts distributors, which makes a repair worth pricing rather than writing off.

What this page does not cover
This page covers the Sharp refrigerator as a class, not one family or model line. Where a family- or model-specific page exists for your unit it is linked above and it is the better answer — read it first. Deliberately not here: part numbers, wiring colours, panel removal order and torque figures, all of which differ between families under one nameplate.
