The short answer for URBC models
When an Avanti URBC refrigerator stops making ice, work the chain in order: is water arriving, is the compartment cold enough to freeze it, and is the harvest mechanism cycling. On these machines the first two links account for most cases, and both are checkable without opening anything up.
What owners describe
- You can hear the fill valve buzz but no water comes — Looking at URBC models specifically, a buzzing valve with a dry mould is a supply fault almost every time.
- The bin is empty and the mould is dry — Where URBC models are concerned, a dry mould is the clearest possible pointer: look at the valve, the line and the pressure.
- The mould fills but the cubes come out hollow or small — For URBC models, hollow cubes are the classic sign of a compartment that is not cold enough for long enough.
- Production is slow rather than absent — On URBC models in particular, halved output usually means temperature, not a failed part.
- Cubes have fused into one lump in the bin — On the URBC models listed below, clumping tells you the bin is warming between cycles.
- NEAR MISS — nothing in the cabinet is properly cold — Then ice is the least of it: the cooling-failure page is the right place, and ice will return when cold does.
Likely causes for URBC models, most common first
- A closed, kinked or frozen water supply — It leads because the machine cannot make ice out of nothing, and the whole supply chain is checkable without tools.
- The bin-full arm or sensor stuck in the full position — This one is high value for how cheap it is: look before you diagnose anything else. Nothing in the URBC line changes that order.
- A bin of old ice that never turns over — Ice sublimates and shrinks in a dry compartment, so a bin nobody empties ends up full of small, fused, stale cubes.
- A failed ice-maker module or its wiring — It comes last because everything above it imitates it perfectly and costs less to rule out. It is ranked the same way on every URBC model.
What to look at first, second, third
- Look at the bin-full arm or sensor first — On the URBC line, clear the bin, make sure the arm swings freely, and give it a cycle before going further.
- Put a thermometer in the freezer compartment — A freezer holds food safely at 0 °F (−18 °C) or below, and an ice maker needs that to cycle properly.
- Give it a full day after any change before judging — Ice production is slow by nature and a first harvest after a restart can take hours.
- Put a thermometer in the compartment overnight — Across the URBC line, a reading above it explains hollow cubes, slow harvests and fused lumps at once.
Before you take any panel off
Safety
Isolate the refrigerator at the plug or the breaker before any access; a capacitor can stay charged after the power is off. Close the water supply before touching a fill line, and thaw ice with warm water or time rather than a screwdriver. Leave every switch and sensor exactly as the maker fitted it.

When to hand it over
Call once the bin has been emptied, the arm is free, the supply valve is open, the line is not kinked and a thermometer says the compartment holds temperature — and there is still no ice. What is left is the fill valve, the mould heater or the maker module, and all three sit behind a panel with mains in it.
