The short answer
When a Dongguan Shengqi Lighting Technology refrigerator stops making ice the water path is the first suspect, not the maker itself: a closed valve, a kinked line or a frozen fill tube stops everything downstream. Work the ranking below in order, because the cheap causes sit at the top of it and the module itself sits near the bottom.
What you are seeing and hearing
- Ice is made but the cubes are hollow, small or cloudy — Partial fill and poor water are different faults from no fill.
- There is no model information on the unit that anyone recognises — A factory relabel often carries a number that no parts catalogue lists.
- NEAR MISS: water is pooling under the unit or inside the freezer — That is a leak and the leak page covers it.
What it usually turns out to be, ranked
- No water arriving at the maker — A shut-off valve nobody has touched in years, a kinked supply line behind the unit or a fill tube that has frozen solid all stop the process before it starts. Ranked first on a Dongguan Shengqi Lighting Technology refrigerator: nothing downstream can work until water actually arrives, so the supply is proved first.
- The maker switched off, or its arm held up by the ice already in the bin — Every maker has an arm or a switch that stops production when the bin is full, and a bag of shopping leaning against it stops production just as effectively. Ranked second on a Dongguan Shengqi Lighting Technology refrigerator: owners of a relabelled unit rarely get a useful manual with it, so the habits around the machine explain a great deal.
- A water filter at the end of its life — A clogged filter throttles the flow so that the maker fills only partly, which gives hollow and undersized cubes rather than none at all. Ranked third on a Dongguan Shengqi Lighting Technology refrigerator: everything downstream depends on it, so it is cleared before the pump is suspected.
- A freezer that is not cold enough to trigger the cycle — The maker will not harvest until its mould reaches its cut-out temperature. Ranked fourth on a Dongguan Shengqi Lighting Technology refrigerator: air movement is what actually does the work here, so a blockage shows up as a failure long before anything fails.
The order to work in, and the reason for it
- Trace the supply line from the valve to the back of the unit and check the valve is fully open — A half-open valve behaves exactly like a failed maker.
- Look at whether the arm is down and the switch is on — This is the check that costs nothing and settles a surprising share of calls.
- Note whether the drinking-water dispenser has also slowed — Both slowing together points straight at the filter.
Owner checks, in order
- Open the shut-off fully, straighten any kink in the line and give the unit a day — Pushing the unit back too far is the usual way the line gets kinked.
Tools: torchAbout 20 min
- Lower the arm or switch the maker on, clear the bin and wait a day — A maker with a full bin looks broken and is not.
About 10 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the unit or switch off its breaker before removing any panel: a capacitor can hold a charge after the power is off. Refrigerant work is licensed work, so never cut, bend or solder the tubing, and never run the unit with the sealed system open. A loaded refrigerator is heavy and top-sided, so get help to move it rather than walking it on a corner.
Where an owner fix ends
Call when the valve is open, the line is clear, the filter is fresh and the freezer is properly cold, and the maker still does nothing: what is left is the module, the fill valve or a harness, and all three need a meter. Call sooner if you can see water leaking from a fitting behind the unit, because a slow leak behind a refrigerator does expensive damage quietly.

What this page does not cover
This page is written for the Dongguan Shengqi Lighting Technology refrigerator as a class, not for one family or model line. Shelf layouts, defrost-control types, fan placement and part numbers all change from build to build and are deliberately not here. Where a family- or model-specific page exists for your unit, it is the more specific answer and the one to read first.
