Start here
An icemaker that has stopped is usually a water supply problem or a temperature problem, and the two look nothing alike once you know what to look at. Hollow or small cubes say one thing; an empty, dry mould says another entirely. On an FDLQEOR refrigerator the place to start is the fill tube and how the unit sits, because these are small single-evaporator cabinets with one thin magnetic gasket and no second air path, so anything that loads the door or the drain shows itself long before the sealed system does.
What you are looking at
- Cubes are hollow, small or half formed — Water is arriving but not enough of it, or not for long enough per fill.
- Cubes are made but stay stuck in the mould — The maker is filling and freezing but not harvesting, which is a mechanism fault rather than a supply one.
- Ice tastes or smells wrong — Old ice sublimates and takes on cabinet odours.
- NEAR MISS: the freezer itself is not properly cold — Then the icemaker is a symptom and not the fault.
What it usually is, in order of likelihood
- A frozen or misdirected fill tube — The small tube that squirts water into the mould freezes shut if the fill valve weeps, or misses the mould entirely if the cabinet is not level. Ranked first on an FDLQEOR refrigerator: this is marketplace-sourced equipment with no single service literature behind it, so the checks run from what is universal, and supply and power come before any part.
- No water reaching the maker — A closed saddle valve, a kinked supply line behind the cabinet, a filter that has never been changed or a line frozen where it passes through the cabinet wall all end the same way: an empty mould and a maker cycling on nothing Where it sits here: the most common cause of a dead icemaker anywhere, and every part of it is checkable without opening the appliance.
- The maker is switched off or the arm is held up — Every icemaker has a bail arm or a switch that stops production when the bin is full. Where it sits here: trivial, free and genuinely common, so it always belongs near the top of the list.
- The freezer is not cold enough to complete a harvest — An icemaker will not harvest until the mould thermostat sees its release temperature. Where it sits here: ranks high whenever the cabinet is also running long cycles, because then the two complaints are one fault.
The order to work in
- Start at the fill tube and how the unit sits — It is the cause that ranks first on this kind of machine, so it is the check that ends the diagnosis most often and the one that costs least to make.
- Look in the mould and say whether it is wet or dry — Dry means the supply side; wet, frozen and stuck means the harvest side.
- Check the bail arm and the maker switch — Free, instant, and it resolves a surprising share of dead icemakers before any panel comes off.
Owner-side checks, step by step
- Straighten the supply line and open the valve fully — Pull the cabinet out far enough to see the line, remove any tight bend and confirm the shut-off valve is fully open rather than cracked.
Tools: flashlightAbout 25 min
- Change the water filter and flush the line — Run several quarts through the dispenser afterwards to clear air.
Tools: replacement filterAbout 20 min
- STOP HERE if the mould fills but never releases — Mould heaters and harvest motors are tested with a meter on a live or dismantled maker.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Do not thaw a frozen fill tube with an open flame or a heat gun on high, because the surrounding plastic melts long before the ice moves. Shut the water supply off before disconnecting any line, and be ready for the water the line still holds.
When this becomes a service call
Call once the supply side is proven good and the mould still fills without harvesting, or when ice is building behind the maker rather than in it. Call sooner if the ice complaint sits alongside a freezer that is not holding temperature, because then the icemaker is the messenger and the cooling fault is the message.

The limits of this page
This page covers FDLQEOR refrigerators as a class, not one family or model line. Where a family- or model-specific page exists for your unit, that is the more specific answer and the one to read first. Deliberately not here: maker assembly part numbers, fill-valve flow ratings and the mould thermostat tables, all of which differ by family.
