The short answer
An ice maker that has stopped producing: on an ILVE refrigerator that is usually a freezer too warm to release ice, not a failed ice-maker module. If that is clean, a supply that is not delivering is next. Most causes below are owner checks needing no tools and no panel off; the last is a service call.
What you are looking at
- There is an ice plug at the back of the compartment — Water froze before it reached the mold.
- Cubes sit frozen in the mold and never drop — The fill worked and the harvest did not.
- The bin is empty and stays empty — No cubes arrive over a full day with the maker switched on.
- NEAR MISS -- this cabinet has no plumbed maker at all — A manual tray or a portable box makes ice only as fast as the freezer pulls down, which is not a fault.
Causes, most likely first on this kind of unit
- The freezer is not cold enough to harvest — An ice maker will not release a harvest until the mold reaches its release temperature. First here, because on an ILVE appliance with a heavy door on stiff hinges on this kind of cabinet the freezer is the marginal part, so temperature comes before any part swap.
- The supply is shut, throttled or the valve is not opening — A shutoff left part-closed after a move, a saddle valve barely cracked, or an inlet valve that is not opening gives too little water for a full harvest. This rank, because too little water means small, hollow or no cubes.
- The fill tube or the fill cup is frozen — A slow fill dribbles and refreezes at the tube mouth until the path closes. Ranked here because an ice plug at the tube mouth stops the water before the maker ever sees it.
- The maker module, mold heater or harvest motor — A module that will not cycle, a dead mold heater or a seized harvest motor leaves full cubes stuck in the mold. It comes last because it is the one cause here that is not an owner repair, so it is checked last.
Check in this order, and why
- Measure the freezer, not the fresh side — A freezer holds food safely at zero degrees Fahrenheit or below; above that, fix the cold first.
- Open the shutoff fully and check the line — Full-open the valve, then dispense water if the unit can; a weak stream points at the supply.
- Only after water and temperature are proven — Cubes frozen solid in the mold with a cold freezer and good fill is the signature -- and that is a service call.
What an owner can safely check
- Lift the bail arm, clear and re-seat the bin — Then switch the maker on and note the time; a harvest takes hours, not minutes.
About 5 min
- Measure the freezer with a thermometer — A freezer at or below zero degrees Fahrenheit can harvest; a warmer one cannot.
Tools: thermometerAbout 10 min
- Full-open the shutoff and check the line behind the cabinet — Look for a crushed or kinked section, and straighten what you find.
Tools: flashlightAbout 15 min
- STOP HERE -- the next step needs a meter on the module — Mold heaters, harvest motors and module timing are technician work.
Before you open anything
Safety
Power off at the plug or the breaker before any panel comes off.
When to call a technician
The line is simple: anything you can reach without a panel is yours, anything behind a panel or on the sealed system is a technician's.

What this page does not cover
This page covers the ILVE refrigerator as a class, not one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer -- go there first if your model is named. Deliberately not here: module part numbers, harness colours, fill-volume adjustment and the exact harvest timing, all of which differ by family.
