What this usually is
On these models the icemaker is a passenger: it makes ice only when the freezer is cold enough and the water is arriving, so both of those get tested before the icemaker itself. The commonest single finding is a fill tube frozen solid, which looks like a dead icemaker and is a twenty-minute thaw. The mechanism itself is the last thing to suspect, not the first. The second column is the family key, and the first is what the rating plate will say.
What is in the bin, and what it means
- Ice tastes or smells wrong — A filter at the end of its life, or ice that has been in the bin long enough to absorb everything else in the freezer.
- Cubes are small but properly formed — A short fill rather than a blocked one. Suspect a restriction in the filter or a partially closed supply tap.
- Ice production stopped after the filter was changed — Air trapped in the line after a cartridge change. It usually clears after several dispenses, and it is not a fault.
- Ice is being made but far too slowly — Usually a compartment that is not quite cold enough, or a restricted supply that fills the tray part way.
- A slab of ice in the bin rather than cubes — Melt and refreeze, which means the compartment temperature is swinging rather than holding.
- NEAR MISS — water is leaking outside the cabinet — A supply leak is its own page and its own urgency; deal with the water before the ice.
The ranking for this platform
- Fill tube frozen — Top of the list here. The tube crosses from warm into cold and the last of each fill sits in that crossing; freeze it once and the mechanism harvests nothing from then on.
- Shut-off arm or bin sensor holding the mechanism off — The cheapest fault here. An arm lifted by a bag of frozen peas, or a sensor beam interrupted by frost, tells the icemaker the bin is full when it is empty.
- Freezer not cold enough to trigger a harvest — The mechanism has its own thermostat and will not eject until it is satisfied, so a compartment a few degrees warm gives you no ice rather than slow ice.
- Water inlet valve or icemaker module failed — Last on the list. Both are real failures and both need testing rather than guessing, which is where this page hands over.
What to check first, second, third
- Check the shut-off arm is down, or the bin sensor is clear — An arm held up by a stored bag stops production completely and takes a second to rule out.
- Force a harvest cycle and watch what the mechanism does — A mechanism that goes through its motions and delivers nothing has a supply problem, not a mechanical one.
- Time how long the dispenser takes to fill a cup — A crude flow measurement, and the cheapest way to see a restriction before it reaches the tray.
Safety before diagnosis
Safety
Pull the plug, or trip the breaker if the machine is hard-wired, before a single screw comes out — and remember that a capacitor stays charged after the supply is gone. If the cabinet has to come out to reach the supply valve, remember it is heavy and unbalanced once a door swings.

Where the owner line is
Stop at the point where the supply path is proven good. Everything after that is electrical testing inside a cold cabinet, which is service work on this roster.
