What this usually is on PDR cabinets
Ice is the last thing a refrigerator does and the first thing it stops doing, so on a PDR cabinet a slow or absent ice supply is often the earliest sign of something else. A freezer section that is running a little warm makes ice slowly long before anything else looks wrong. That is why temperature comes into this diagnosis as early as it does.
The observable symptoms
- The mould is completely dry — No water is arriving, so the fault is upstream of the ice maker rather than in it.
- Cubes are hollow, small or only partly formed — A short fill, which usually means restricted supply rather than no supply.
- One solid block instead of separate cubes — The harvest cycle is not releasing, or cubes are melting and refreezing in the bin.
- NEAR MISS — the cabinet has no factory ice maker — Not every model under this stem is fitted with one. If there is no mould and no arm inside the freezer section, there is nothing here to repair.
The ranked causes for this family
- Freezer section not cold enough to cycle the mould — An ice maker only harvests once the mould reaches its release temperature, so a compartment running a few degrees warm makes ice slowly or stops entirely. Ranked first on PDR: every model under this stem has the part, so it is the one cause that cannot be excluded by knowing which code you own.
- Bin jammed, or the arm held up by the ice already in it — The arm stops production when the bin is full, and a bridged clump of old ice holds it up while the bin is half empty. Ranked second because it explains the cases the first cause does not, and because on this family the two are checked from the same side of the cabinet.
- Water supply shut off, kinked or restricted at the valve — The supply usually starts at a small valve under a sink or behind the cabinet, and that valve is the part most often found half closed or silted up. Ranked third here, because the two causes above it are both quicker to settle and more often the answer on a cabinet of this size.
Work through it in this order
- The order for PDR cabinets — It is arranged so that everything visible from inside the compartment is settled before anything behind or beneath the cabinet is touched.
- Judge the freezer section by the food in it — Ice cream that is soft and packets that flex are a temperature answer, not an ice maker answer.
- Empty the bin completely and break up any bridged ice — Then let the arm fall and give the machine a few hours before judging it.
- Follow the line back to its shutoff and open it fully — Then look along the line for a kink where the cabinet meets the wall.
Before any panel comes off
Safety
Switch the breaker off or unplug the unit before removing any panel; a capacitor can hold a charge after the power is off. Anything you do behind the freezer rear panel happens next to a fan blade that the door switch is there to stop, so leave that switch alone.

Where the owner fix stops
The honest limit is the rear panel. Behind it are components that need testing rather than looking at, and on a cabinet this size they sit close enough together that a probe in the wrong place breaks something that was working.
