The short answer
On a U refrigerator the usual explanation for an ice-making fault is a duty problem rather than a broken part: a box set and supplied for refrigerator duty will chill happily and never make ice, and the fix is in the settings and the supply rather than in the cabinet. Work the order below rather than the order of expense: the two cheapest checks settle most of these before a tool comes out.
What you actually observe
- Ice forms as a thin skin and then stops — The plate is getting there and then losing it, which points at cycling rather than at a dead compressor.
- Frost coats the plate but the contents stay soft — Frost is an insulator; the cold is trapped on the plate instead of reaching what sits beside it.
- Ice forms only on one side of the compartment — Contact and airflow: what touches the plate freezes, what does not, will not.
- The whole box is warm and nothing is cold at all — NEAR MISS: that is a cooling failure, and the not-cooling page is the better read of it.
- Body: No two U listings share a base number, so each one in the table is a distinct machine rather than a revision of its neighbour.
Causes, most likely first on the U platform
- 1. The set point and the operating mode — Before anything is suspected, the set point has to be low enough to freeze and the mode has to allow the compressor to reach it. Most reports of no ice end here. It ranks high because across four U listings the same usage pattern lands very differently depending on which one you own.
- 2. Warm air leaking in past the seal — A seal that leaks costs the last part of the pull-down, which is exactly the part that makes ice. Chilling survives a leaking seal; freezing does not. Second on U: it is as common as the cause above it but takes longer to prove, so it is checked afterwards.
- 3. Supply voltage and the battery-protection cutoff — The tell is that chilling still works.
- 4. The control module that sets compressor speed — The module decides how hard the compressor runs.
What to check first on these U models, and why
- 1. Read the set point and the mode on the panel — Costs nothing and settles the most common cause before any hardware is suspected.
- 2. Check the seal along its whole length with a sheet of paper — Drag on every side is a good seal; a slide anywhere is a leak.
- 3. Run it overnight from a known-good supply — Freezing needs uninterrupted run time; only a stable supply proves whether it can get there.
Before you open anything
Safety
Isolate first: unplug the appliance or switch off its breaker before any panel comes off, and treat a capacitor as charged after the power is gone. Ice comes off with time and a cloth, never with a blade, because what is directly behind the frost is refrigerant tubing. With four listings in the U table, quote the full model number when ordering anything: the differences between them are exactly the differences that matter to a parts counter.

When to call a technician
Call when the set point, the supply, the frost and the seal are all clean and the compartment still will not freeze. That combination has run out of owner checks, and what remains is the compressor module or the sealed system.
