The short answer
An ice maker that has stopped producing: on an Iceco refrigerator that is usually a freezer too warm to release ice, not a failed ice-maker module. If that is clean, a frozen fill tube is next. Work the order below -- cheap causes first, the one that is not an owner fix last.
What you are looking at
- Cubes are small, hollow or misshapen — The maker is cycling but the fill is short.
- 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.
- 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. Ranked first on an Iceco box running from a vehicle or auxiliary battery: on this kind of cabinet the freezer is the marginal part, so temperature comes before any part swap.
- The fill tube or the fill cup is frozen — A slow fill dribbles and refreezes at the tube mouth until the path closes. This rank, because an ice plug at the tube mouth stops the water before the maker ever sees it.
- The maker is switched off, or the bin is not seated — A bail arm resting on ice, a bin pushed in crooked, or an off switch left from a previous fill all stop production with nothing broken anywhere. Placed here: a maker that thinks the bin is full does exactly this.
- 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. Bottom of the list, deliberately: 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.
- Look for an ice plug at the fill tube — Thaw it with warm water and watch the next fill; a repeat plug means the supply is too slow.
- 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.

- 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
Call once the condenser, the seal, the set point and a full defrost are all ruled out.

What this page does not cover
This page covers the Iceco 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.
