The short answer
An ice maker needs three things: water arriving, a freezer cold enough to harvest, and a module that is switched on and not jammed. Nearly every no-ice call is one of the first two, and both are owner-checkable. Lift the mould and look. An empty mould means water is not arriving; a mould full of solid ice means the harvest is not happening, and those are opposite faults. On a Smith & Hanks refrigerator the cause that ranks first is fill tube or inlet valve frozen.
What you observe
- The dispenser also runs slowly — Water supply, which is the same fault seen from the door.
- The mould is empty and has been for days — Water is not arriving: supply, filter, valve or a frozen fill tube.
- NEAR MISS — water leaks from the dispenser area — That is a leak, and it belongs on the water-leak page.
Causes, most likely first on a Smith & Hanks refrigerator
- Fill tube or inlet valve frozen — A slow drip freezes in the fill tube, the next fill backs up, and a plug of ice grows until nothing reaches the mould at all. It ranks first on a Smith & Hanks refrigerator because a built-in installation breathes through a narrow cabinet cut-out, so anything airflow-related surfaces here long before it would on a free-standing machine.
- Water filter clogged or past its life — A filter at the end of its life restricts flow enough that the mould underfills or never fills, and the dispenser slows at the same time. Second on this platform: a slow dispenser alongside no ice is this and nothing else.
- Freezer not cold enough to trigger a harvest — The mould thermostat will not release ice until the freezer is properly cold, so a cabinet running a few degrees warm makes no ice while still freezing food. Ranked here because a freezer that is cold but not cold enough makes no ice while looking perfectly healthy.
- Ice maker arm or sensor in the off position — The wire arm or the switch that stops the maker when the bin is full is left up, knocked up by a bag, or reading a bin that is not seated. Last, and the reason to work down the list rather than guess: it is the free check that solves a surprising share of no-ice calls, so it comes before anything is dismantled.
Check in this order, and why
- Look at the fill tube at the back of the freezer for a plug of ice — A visible plug ends the diagnosis on the spot.
- Fill a glass at the dispenser and time how fast it runs — A slow dispenser and no ice together point straight at the filter.
- Put a thermometer in the freezer overnight and read it in the morning — A freezer holds food safely at zero degrees Fahrenheit or below.
What an owner can safely check
- Thaw the fill tube with a hair dryer on low, held well back, with the cabinet unplugged — Never use anything sharp or anything that gets hot enough to melt plastic.
Tools: hair dryer, clothAbout 25 min
- Replace the water filter and flush several litres through the dispenser — Run water through until it stops spluttering before judging.
Tools: replacement filterAbout 20 min
- STOP at the point where the next check means live terminals or a panel removed — Everything past that line is a technician's work, however likely the cause above it looks.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before reaching behind the ice maker or thawing a fill tube, and shut the water supply off before disturbing any plumbed joint.
When to call a technician
Call when the filter, the supply and the temperature are all ruled out, and sooner if the freezer itself is not holding temperature. On a beverage cabinet, ask for the seal and the drain to be checked at the same visit: the humidity behind one is usually behind the other.

What this page does not cover
What this page covers is the refrigerator class as Smith & Hanks builds it, not an individual family or model line. If a page exists for your particular family or model, it is linked above and it is the better answer — go there first when your model is named. Left out on purpose: part numbers, connector colours, disassembly order and torque values, because every one of those varies by family.
