The short answer
The URBC roster covers a small group of closely related cabinets, and its entries differ only in the trailing finish position. The most common cause of no ice on a cabinet like this is not the ice maker at all. It is the supply to it, the temperature around it, or the arm and bin sensor that tell it to stop, and all three are reachable without tools.
What you observe on these models
- Ice with an odour or a taste — A filter that is overdue, or cubes that have been sitting and absorbing what is around them. Neither is a mechanical fault.
- Production that stopped after the cabinet was moved — The supply line or the fill tube has shifted. Timing that specific points away from the mechanism entirely.
- No ice at all and a dry mould — Nothing is arriving. The diagnosis is the water route: the shut-off arm, the supply, the valve or a frozen fill tube.
- A mould with water in it that never freezes — Water is arriving and the compartment is not cold enough to complete a cycle. That makes it a temperature fault wearing an ice-maker costume.
Causes, most likely first on the URBC line
- Shut-off arm raised or bin sensor blocked — Ranked first on this roster: nothing about the cabinet looks wrong in this case, which is why it survives so many self-diagnoses.
- Water filter overdue and restricting flow — Ranked second on this roster: a filter at the end of its life restricts flow enough to produce a partial fill long before it stops water altogether, and hollow or small cubes are the signature.
- Supply line, shut-off valve or house pressure — Ranked third on this roster: nothing arrives if the line is kinked behind the cabinet, the shut-off was closed after other work, or the supply pressure is below what the fill valve needs to open properly.
- Ice maker module or mould heater failed — Ranked last on this roster: reaching it honestly is a result, because it turns the question into whether the assembly is worth replacing.
- Body: Where this ranking departs from the brand-generic order is water filter overdue and restricting flow, which moves up on the URBC line because the roster is a small group of cabinets built the same way, so the order follows their shared construction rather than an average across the brand.
Check in this order, and why
- Look at the arm or sensor path before anything else — Lower a raised arm, clear anything sitting in front of a sensor, and give it a few hours.
- Check the filter age and that it is fully seated — Replace an overdue filter and re-seat a recent one. Then allow a day before judging the cube size.
- Trace the line from the shut-off to the cabinet — Look for a kink, a closed valve and a line that has been trapped behind the cabinet. Pull the cabinet out to check properly.
- Have the module tested rather than replaced on suspicion — Cubes fully formed and never released point here, but every cause above it is cheaper and should be cleared first.
Before you open anything
Safety
Switch off at the breaker before any panel comes off and before putting a hand into the ice maker housing, because the harvest mechanism moves under power and does not warn you. Close the household shut-off before touching a supply fitting; a line under pressure behind a heavy cabinet is difficult to stop once it starts. Use warm water on an ice plug, never a tool, and keep water away from the supply cord throughout.

When to call a technician
Call when cubes form fully and never release, because that pattern points at the harvest side and nothing an owner can reach will change it. Call immediately if you find water anywhere around the supply fitting, and close the household shut-off before you do: a leaking supply behind a heavy cabinet does far more damage than a week without ice.
