The short answer
The usual answer on this unit is water supply shut off, kinked or never fully opened, with a frozen fill tube or fill cup close behind. Both are upstream of the ice maker itself. The first three checks cost nothing and rule out most of the list.
What you actually observe
- It cycles and fills but the cubes come out small or hollow — Water is arriving, but not enough of it.
- Cubes are stuck together in one block in the bin — Ice that melted and refroze, which points at the freezer temperature rather than the maker.
- NEAR MISS: the whole cabinet is warm — Then this is a cooling fault, and the ice maker is a symptom rather than the problem.
What it usually turns out to be, in order
- Water supply shut off, kinked or never fully opened — The saddle valve behind the unit gets closed for a plumbing job, knocked when the fridge is pushed back, or was never opened fully after installation. It leads the list on a White House refrigerator because it is the first thing disturbed whenever the unit is moved, and moving a refrigerator is exactly what happens before this fault appears.
- A frozen fill tube or fill cup — A slow trickle at the end of the fill freezes in the tube instead of running into the mould. Second: on a cabinet that is opened often the fill end sits in the coldest, wettest air in the appliance, so it is where ice forms first.
- The bail arm or shut-off lever left in the off position — Every ice maker has a mechanical or infrared level sensor. Third, once the two above are clean: it is the cause that costs nothing to rule out and the one that is most often the whole answer.
- A failed ice maker module or harness — The motor, thermostat and heater live in one sealed module. Bottom of the list, deliberately: everything above it produces the same empty bin for a fraction of the cost.
What to check first, second, third
- Trace the water line behind the unit and check the valve is fully open — A closed or half-turned valve explains every symptom on this page at once.
- Look into the fill tube at the back of the ice maker for a plug of ice — Ice visible there ends the diagnosis on the spot.
- Check the bail arm is down, or that nothing blocks the level sensor window — The cheapest check on the page and the one to do first if the bin is not full.
Owner-side checks, step by step
- Pull the unit out and follow the water line back to its shut-off valve — Open it fully. Check the line is not crushed against the wall.
About 15 min
- Look at the fill tube where it enters the ice maker and thaw any plug with warm, not hot, water — Never chip ice out with a knife or a screwdriver.
Tools: warm water, a clothAbout 20 min
- STOP AT THIS POINT if the fault is on the sealed system — Refrigerant is licensed work and the tools for it are not owner tools.

Safety
Pull the plug or drop the breaker before you take off a panel. There is a capacitor in this appliance that stays charged after the power is gone, and the compressor terminals are live whenever it is not. Do not rewire or bypass a door switch to keep a fan running while you look. Refrigerant work is licensed, so the sealed system is a technician's job from the first step to the last.
Where an owner check ends
Call once water is confirmed arriving at the mould and the freezer is holding temperature, because at that point the fault is inside the module or its harness. Call sooner if you find water anywhere it should not be, or if the unit trips a breaker when the ice maker tries to cycle.

What this page does not cover
This page covers the White House refrigerator as a class, not one family or model line. Where a family- or model-specific page exists it is linked here. Deliberately not here: module part numbers, fill-volume adjustment, valve resistance figures and any harness pinout, all of which differ by family and belong on the page for that family.
