The short answer
An ice-making fault on a QX refrigerator usually comes down to the plate losing contact with what it is meant to freeze, whether through frost, packing or a tray that never touches it. The order that follows puts the likeliest and cheapest causes first, and it is the order worth working in rather than starting with the part that sounds most serious.
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.
- Drinks are cold but nothing in the compartment freezes — The classic split: refrigeration is working, freezing duty is not being reached.
- Everything freezes including what should not — NEAR MISS: that is over-cooling, a set point and thermostat question rather than this one.
- Body: With three listings in the QX table, quote the full model number when ordering anything: the differences between them are exactly the differences that matter to a parts counter.
What causes it on the QX platform, in likelihood order
- 1. The conditions it is being asked to work in — Freezing takes far more out of a small compressor than chilling does, and every degree of ambient heat takes capacity away from it. It ranks high on QX because the three listings differ in capacity, so the same habit that suits QX20 overloads nothing and the same habit at QX40 matters more.
- 2. 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. Second here because it costs nothing to ask, while the cause above it explains more of what owners report on QX.
- 3. A supply the controller keeps rejecting — Freezing is the duty that needs the longest uninterrupted run. A supply that sags under load makes the controller stop the compressor early and often, which is enough to hold a chill but never enough to freeze.
- 4. Contact between the plate and what is being frozen — Air is a poor conductor and packaging is worse.
The order to work in on this platform
- 1. Move it out of direct sun and away from anything warm — Ambient heat is capacity, and capacity is what freezing duty runs out of first.
- 2. Read the set point and the mode on the panel — Costs nothing and settles the most common cause before any hardware is suspected.
- 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
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. Where a step below depends on which QX listing you own, the table above is the reference; nothing here is written from a model outside it.

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.
