The short answer
A Craftsman cabinet that has stopped producing ice is more often obeying something than failing at it, whether that is a raised arm, a warm setting or a specification that never included freezing. On this class the usual cause is a freezer compartment too warm to complete a harvest, with the fill tube frozen solid next to rule out.
What you actually observe
- Cubes weld into a mass after a hot day — Part-thawed ice refreezing is a temperature story.
- The bin stays empty day after day — A unit that makes nothing at all is a different list from one making poor ice.
- NEAR MISS: the whole cabinet is warm and the ice is only the first thing you noticed — Then the cooling page is the one to read, because ice is simply the most sensitive symptom.
The causes, most likely first on this brand
- A freezer compartment too warm to complete a harvest — An ice maker only ejects when the mould reaches its harvest temperature, so a freezer running warm simply holds a tray of water indefinitely. Ranked first on a Craftsman unit: a garage swings between a cold night and a hot afternoon, and the harvest is the first function to be lost on the hot end.
- The fill tube frozen solid — Water left standing in the fill tube after a slow fill freezes there, and every later fill then backs up before it reaches the mould. Ranked second here: the same swing refreezes standing water in the tube on the cold end.
- The shut-off arm raised or the sensor beam blocked — Ranked third here: a garage cabinet is loaded in bulk, which is exactly how an arm gets knocked up.
- Cubes clumped in the bin around a stalled auger — Ranked fourth here: last, and it is the classic result of ice that part-thawed on a hot day.
Check in this order, and why this order
- Put a thermometer in the freezer overnight and read it in the morning — A freezer holds food safely at 0 °F (-18 °C) or below, and an ice maker expects roughly that.
- Look at the fill tube where it enters the ice maker — A plug of ice at the mouth of the tube is visible with a torch and without removing anything.
- Look for the wire arm or the sensor window beside the ice maker — An arm sitting up, or a package across the beam, is the commonest no-fault cause on this page.
What an owner can safely check
- Set the freezer colder and leave it a full day before judging — A harvest that restarts on a colder setting was never an ice maker fault at all.
Tools: thermometerAbout 10 min
- Thaw the fill tube with a cloth wrung out in warm water — Never use anything sharp and never use a heat gun near the liner.
Tools: clothAbout 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 unit or switch off its breaker before any panel comes off, and close the water shut-off before disturbing any fitting on the supply line. Never thaw a fill tube with a heat gun or an open flame, because the liner and the tubing behind it will not survive it. Never chip ice from a plate or a mould with a tool.
When to call a technician
Call once the supply, the temperature and the simple mechanical checks are all clean, because a fill valve or an ice maker module needs a meter and a panel off. Call sooner if you find water where it should not be, since a supply fault that leaks costs more the longer it runs. Bear in mind when you decide that a garage unit lives outside the conditioned envelope, which changes what counts as normal before anything is diagnosed.

What this page does not cover
This page covers the Craftsman refrigerator as a class, not one family or model line. Ice maker module types, fill volumes and filter part numbers all change from build to build and are deliberately not here. Where a family or model page exists for your unit, it is the more specific answer and the one to read first.
