The short answer
On an S refrigerator, an ice-making fault is most often the supply cutting the compressor short: freezing is the last duty a small compressor gets to, so it is the first duty lost when the controller keeps stopping it. The causes below are in likelihood order, cheapest first; working down that order costs less than starting with the part that sounds most alarming.
What you actually observe
- Ice forms only on one side of the compartment — Contact and airflow: what touches the plate freezes, what does not, will not.
- 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.
- It freezes on mains power but not from the vehicle socket — A supply difference, not an appliance difference.
- Everything freezes including what should not — NEAR MISS: that is over-cooling, a set point and thermostat question rather than this one.
- Body: The S roster is a single listing, S15, so everything here applies to one build rather than to a range.
Ranked causes on these S models
- 1. What the box has actually been asked to do — A unit set for chilled storage will hold that set point exactly and never freeze anything, and the display gives an owner no hint that the two duties differ. Most reports of no ice end here. It ranks high on S because with one listing the appliance is a constant, which leaves how it is used as the main variable.
- 2. Supply voltage and the battery-protection cutoff — The tell is that chilling still works. The compressor is getting run time, just not the long run time freezing needs, and that is a supply symptom rather than a cooling-capacity one. It sits second here rather than first because the cause above it is cheaper to rule out, not because this one is rarer.
- 3. The control module that sets compressor speed — The module decides how hard the compressor runs. Stuck at its lowest speed, or protecting itself from a fault it keeps seeing, it will deliver refrigeration duty and never deliver freezing duty.
- 4. Ambient heat and what is being frozen — A box that froze in winter and will not in summer has not developed a fault. In a warm vehicle with a warm load, freezing duty is the first thing to disappear.
Check in this order on the S platform
- 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. Run it overnight from a known-good supply — Freezing needs uninterrupted run time; only a stable supply proves whether it can get there.
- 3. Listen for whether the compressor changes speed at all — A compressor that only ever runs at one slow speed points at the module.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Never chip ice off a plate with a knife or a screwdriver: the tubing behind it is thin-walled, and a puncture turns a free defrost into a sealed-system repair.

When to call a technician
The line is the compressor and its module. A box that chills well and refuses to freeze on a clean supply, in a cool room, with a bare plate, needs a technician rather than another setting change.
