Start here
Short version: the icemaker is usually starved rather than broken. Start at a pinched or frozen supply, upstream of everything else, and give each change a full day before judging whether it worked.
The symptoms, and the ones that mean something else
- A single slab of fused ice in the bin — Cubes that melted slightly and refroze together mean the freezer has been warm at some point.
- Ice production is slower than it used to be but has not stopped — A partly restricted supply or a marginal freezer temperature shows up as a rate change first.
- The bin is empty and the icemaker is silent — No cycle at all usually means no water, no cold enough freezer, or a bail arm that has been lifted.
- NEAR MISS — water is leaking onto the floor from the icemaker area — Water on the floor is a leak page. Deal with the leak first; it usually also explains the ice.
The ranking, and why it is this way round
- A pinched or frozen supply, upstream of everything else — A line pinched by the cabinet being pushed back against it is one of the most common causes of this complaint, and it appears at exactly the moment nobody associates with the icemaker: after a clean behind the fridge. First, because nothing else on the list explains as many of these calls, and ruling it out costs nothing but a few minutes. With a badge like this the practical question behind every check is whether the fix needs a part at all, so the no-part causes are ranked first.
- Water filter clogged or past its service life — A filter restricts gradually as it loads, and the icemaker notices before anyone else does because it fills against a timer rather than against a thumb on a lever. It takes second place because the check is quick and because leaving it unchecked makes everything below it harder to read.
- Bin-full sensor blocked by a stray cube — A single cube that has fallen out of place can hold a bail arm up or block a beam, which is why this cause outranks anything requiring a part. It costs nothing to check and it is right more often than owners expect. It belongs at this point because by now the field has narrowed and the remaining checks cost more time.
- The assembly itself, electrically failed — When water arrives, the freezer is cold, and the bin is empty and the arm down, what is left is the assembly: the module that times the cycle, the heater that releases the cubes, or the valve that admits water. That is a part, and parts mean a visit. Last, and the reason the order matters: it is the least likely of the four, and the three above are quicker to settle.
Check in this order, and why
- Trace the water line to the shutoff and check it is open and not kinked — Do this before anything else — it is the single most common reason an icemaker stops. Begin with this one; everything after it depends on what you find.
- Remove and refit the filter, checking it seats and locks properly — A quarter turn short of home is enough to restrict flow without leaking a drop. Follow with this: it either confirms the second cause or clears it for good.
- Empty the bin completely and check nothing blocks the sensor window — A cube jammed in the beam path reads to the machine as a full bin forever. Leave this one until the cheap checks are done; it is the slowest of the three.
The checks you can make yourself
- Thaw the fill tube with the icemaker switched off — Let it melt on its own or with warm water on a cloth; never chip at it with anything hard.
Tools: cloth, warm waterAbout 45 min
- Change the water filter, then run water through the dispenser until it is clear — Expect trapped air to splutter for a while after a change; that is normal and settles.
Tools: replacement filterAbout 20 min
- Empty the ice bin, wipe the sensor windows, and refit the bin squarely — Do it with the icemaker switched off, then switch it back on and wait a cycle.
Tools: clothAbout 15 min
- STOP if the fault is now down to a sealed or high-voltage part — Those need tools, training and a discharge procedure. Write down what you found and hand it over.
Before you open anything
Safety
Before any panel comes off, unplug the appliance or switch off its breaker, and remember that a capacitor can hold a charge after the power is off. Wipe up spilled water before you start: standing water and a cabinet you are reaching into are a bad combination in a kitchen.
When to stop and call
Book sooner if water is escaping anywhere: a leak outranks lost ice, and an overfilling valve explains both complaints at once.
