Start here
When a WD unit stops cooling, the useful split is whether it makes no cold at all or makes cold it cannot distribute. Work outwards from what the owner can change, because every one of those causes imitates the expensive one, and that distinction decides everything that follows. The order below puts a marginal supply or lead first and a loss of refrigerant charge last, and that order is the point of the page.
The observables
- It was fine until the weather turned — The same unit in the same place, coping in spring and failing in a hot room.
- A sheet of ice on the cold plate — Frost thick enough to feel as a layer, with the cabinet warm despite it.
- It recovers overnight and fails again by afternoon — A pattern that follows the room rather than the machine.
- NEAR MISS - completely silent with no lights — That is a supply or power fault before it is a cooling fault: check what is reaching the unit first.
Causes, most likely first on this line
- A marginal supply or lead — Ranked first on this line: a compressor draws its heaviest current at the moment it starts, and a supply that sags under that load leaves the unit clicking or running without ever pulling down. The cabinet stays warm while everything looks alive.
- A warm load or an overfilled cabinet — It belongs in the ranking because acting on it is free and because ignoring it leads to a wasted service call on a healthy unit.
- A door or lid that is not sealing — Then: on a compact cabinet the ratio of door to volume is large, so a leak that would be tolerable on a full-size refrigerator is decisive here.
- A loss of refrigerant charge — Last, and the reason the order matters: a system that has lost its charge runs continuously, stays quiet, and produces little or no cold at the plate. It is the least likely cause and the only one that decides whether the unit is worth keeping.
The order to work in
- Prove the supply before anything else — Run the unit from a different socket on a different circuit, using its own lead and no adaptor. A unit that cools normally there had a supply problem, not a fault.
- Judge the load and then leave it alone — Ask what went in and when. A big warm load the day the complaint started explains the complaint.
- Test the seal at several points — Close the door on a strip of paper at the top, the middle and the bottom of each side and pull. Anywhere it slides out freely is a leak, and the coldest part of the cabinet will be furthest from it.
Before any panel comes off
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 open pipework or attempt anything on the sealed system - refrigerant work is licensed work and the tools for it are not owner tools.

When this stops being owner work
Call once the supply, the clearance, the seal, the setting, the load and the frost are all clean and the cabinet still makes no cold: what is left is the machinery. Call immediately if you find oil at the machinery end, or if a breaker trips when the unit starts.
