The short answer
The URLC roster records a single model, so nothing on this page has to be hedged across variants, and it is the only entry on that roster, so the rating plate confirms your cabinet in a single step. Ice production failures divide cleanly: no water arriving, water arriving but not freezing, or ice freezing and not releasing. Working out which of the three you have takes one look into the mould and settles most of the diagnosis before any panel comes off.
What you observe on these models
- Hollow, small or misshapen cubes — A partial fill. Low supply pressure, a restricted filter or a valve that is not opening fully all produce the same shrunken cube.
- Ice fused into one block in the bin — Slow production, or a thaw and refreeze event. The cubes sat long enough to bond, which means production has been marginal for a while.
- The arm is up or the bin sensor is blocked — The mechanism has been told the bin is full and is doing exactly as instructed. It is the single most common non-fault on this list.
- 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.
Causes, most likely first on the URLC line
- Shut-off arm raised or bin sensor blocked — It ranks first here because it needs no tool, takes seconds, and is the most common reason a working ice maker produces nothing.
- The compartment is not cold enough to complete a cycle — Ranked second on this roster: it also means the real fault is a cooling fault, and fixing the ice maker would achieve nothing.
- 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 — It ranks last because it is the least likely of these and the only one that means replacing the mechanism rather than correcting something around it.
- Body: The ranking here keeps the brand-generic order, and what the URLC line changes is the order of the checks beneath it: this roster is a single cabinet rather than a line, so the order is what that one machine makes likely and not an average taken across several.
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.
- Look into the mould for standing water — Water present and not frozen means the temperature is the problem. Work the cooling fault instead.
- 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.
