The short answer
On a WH 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.
- It freezes on mains power but not from the vehicle socket — A supply difference, not an appliance difference.
- Ice forms only on one side of the compartment — Contact and airflow: what touches the plate freezes, what does not, will not.
- Everything freezes including what should not — NEAR MISS: that is over-cooling, a set point and thermostat question rather than this one.
- Body: The WH roster covers three listings, WH38 through WH58, and what follows is common to all of them unless a step says otherwise.
Causes, most likely first on the WH platform
- 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. It ranks high on WH because the three listings differ in capacity, so the same habit that suits WH38 overloads nothing and the same habit at WH58 matters more.
- 2. Frost on the plate acting as insulation — This is the cause that gets worse the longer it is ignored, and the only one on the list that clears itself completely with a defrost and a dry cloth. It comes second because the check above it costs nothing, where this one usually means moving the machine.
- 3. 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.
- 4. The compressor controller and its speed setting — Ranked below the supply for a reason: the module rejects a bad supply exactly the way a fault would, so the supply has to be clean before the module can be blamed.
What to check first on these WH 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. Empty it and look at the plate — A coated plate has to be cleared before any other reading means anything.
- 3. 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.
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. No two WH listings share a base number, so each one in the table is a distinct machine rather than a revision of its neighbour.

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.
