The short answer
A Dacor refrigerator ice maker that has stopped is a water-path problem before it is an ice-maker problem, and on a built-in the supply side is harder to see and therefore likelier to be the answer. The state of the tray decides the branch: a dry tray is a supply diagnosis, and a tray holding a solid slab is a harvest diagnosis.
Causes, ranked for this Dacor refrigerator
- Supply stop closed or the line restricted behind the cabinetry — Why: On a built-in the supply stop sits in a cabinet or a wall box that is closed during other work and forgotten, and the line is easily pinched during installation.
- Water filter overdue or restricting flow — Why: A tired filter throttles the fill so the mould only partly fills, producing hollow cubes long before it produces none at all.
- Ice maker switched off or the arm raised — Why: Cheap to eliminate and frequently the answer, since the arm is knocked upward by anything stored beside it.
- Frozen fill tube — Why: One short fill leaves standing water in the tube which freezes, and every fill after that lands on the plug, so the fault compounds and never recovers on its own.
- Ice maker module, mould heater or inlet valve — Why: Last, because everything above imitates it for far less; a solid slab rather than a dry tray is what actually points here.
What to check, in order
- look into the tray and note whether it is dry, holds water or holds solid ice. — Because: that single observation decides whether this is a water-path or a harvest diagnosis.
- confirm the ice maker is switched on and its arm lowered. — Because: it is free, it is common, and every later test is meaningless otherwise.
- test the water dispenser if one is fitted. — Because: water at the dispenser proves the supply into the appliance and narrows the fault to the ice branch.
- check the filter age and look for a plug of ice in the fill tube. — Because: these are the two causes that starve the fill without stopping it entirely.
Checks you can safely do yourself
- Look into the ice tray with a torch and record whether it is dry, holds water or holds solid ice. — Tools: a torch — Time: a minute
- Confirm the ice-maker switch is on and the shut-off arm is lowered, then wait for a fill attempt before concluding anything. — Tools: none — Time: several minutes
- Press the water dispenser, if fitted, and note whether flow is strong, weak or absent. — Tools: a glass — Time: a minute
- Replace the water filter if it is overdue and purge several litres through the dispenser afterwards. — Tools: a replacement filter — Time: several minutes
- Find the supply stop in the adjacent cabinet or wall box, confirm it is fully open, and thaw any plug in the fill tube with a warm damp cloth. Stop here: the valve and module need a meter. — Tools: a warm damp cloth and a torch — Time: the better part of an hour
Before you open anything
Safety
unplug-before-service freezer-0f
Kill power at the breaker before reaching behind the ice maker or removing a panel, and never clear ice with a knife, screwdriver or hot metal, since the fill tube and evaporator tubing puncture easily. A built-in column is heavy and fixed into cabinetry and must not be pulled forward by one person.
Where the owner fix ends
Lowering the arm, changing the filter, opening the stop and thawing the fill tube are owner work. Call a technician when the tray fills and never harvests, since that is the module or mould heater; when the tube refreezes soon after thawing, which means the fill is short rather than blocked; and when the compartment is above the safe holding temperature quoted above.
