LG ice makers in LFXS, LRMVS, LRFVS, LRFXS, and LMXS French-door models share a common set of failure modes — the slim SpacePlus in-door ice maker, the Craft Ice round-cube unit, and the freezer-based tray. We fix every variant with OEM LG parts on the truck. Part of our full LG appliance repair coverage and our Twin Cities ice maker repair service.

Quick answer
Most LG ice maker repairs land $215–$465 all-in. The Craft Ice round-cube assembly (LRMVS, LRFVS, LRFXC) runs higher than the standard cube tray because the part itself is $185–$240. The flat $149 trip fee is credited toward the repair when you approve it. If the display shows an ice-maker or fan error code, we read the diagnostic and quote in writing before any work.
LG ice maker failures
Most common cause: Failed water inlet valve (LG dual-coil valves drop one coil and the icemaker side stops filling while the dispenser still works), frozen fill tube at the back of the freezer, or a failed ice maker fill thermistor.
What we do: Pressure-test the line, thaw the fill tube, swap the dual-coil inlet valve (OEM LG) and confirm the icemaker is cycling on a forced harvest.
$215–$365 all-in
Most common cause: Door seal failure on the ice room (in-door SpacePlus units), a partially clogged fill tube, or — most often — the dispenser door not closing fully because the linkage spring has stretched.
What we do: Forced 12-hour defrost, dispenser door linkage and gasket replacement, fill-tube thaw and reroute as needed.
$265–$425 all-in
Most common cause: Failed Craft Ice module motor or harness fault. The Craft Ice unit is a separate motorized assembly bolted alongside the standard ice maker — it has its own thermistor, motor, and harness.
What we do: OEM LG Craft Ice module swap. We bring the OEM LG Craft Ice module for your model.
$325–$485 all-in
Most common cause: Cracked fill tube, failed inlet valve diaphragm, or overflow because the float / fill thermistor is mis-reading.
What we do: Replace the fill tube and inlet valve, verify the fill volume against the LG service specification for your model.
$245–$385 all-in
Most common cause: Failed dispenser auger motor, broken auger coupling in the bucket, frozen auger from a melt-refreeze event, or a failed dispenser microswitch.
What we do: Auger motor + coupling replacement, dispenser microswitch swap. We thaw and dry the bucket cavity before reinstall so the failure doesn't repeat in 2 weeks.
$235–$385 all-in

Error codes
| Code | Meaning |
|---|---|
| Er IS | Ice maker sensor fault — the ice maker is not reporting correctly to the main board |
| rF | Refrigerator fan / ice room fan fault (often misread as 'ice maker') |
| Er IF / IF | Ice maker fan error — fan in the ice-making compartment stalled |
| Er FF / FF | Freezer fan error — affects ice harvest cycle indirectly |
| Er dH | Defrost heater open circuit — secondary defrost on ice room |
| Er CO | Compressor / inverter communication error — affects all cooling |

FAQs
LG fridges use a dual-coil water inlet valve — one coil feeds the dispenser, the other feeds the ice maker. When the ice-maker coil fails, the dispenser keeps working while the ice maker stops filling. The fix is an OEM LG dual-coil inlet valve, typically a 60-minute repair.
LG refrigerators typically report ice-maker problems as Er IS (ice maker sensor) or Er IF (ice or freezer fan); an IE code is more often an inlet fault on LG washers and dishwashers. An ice maker that stops filling is usually a failed inlet valve, a frozen fill tube, a kinked supply line, or low water pressure. Clearing the code without fixing the cause will bring it back.
Craft Ice module repair runs $325–$485 all-in. The Craft Ice assembly is a separate motorized unit; the part alone is $185–$240 from LG and labor adds 60–75 minutes. If your unit is still under LG's warranty (typically 1 year on most parts) call LG first — they may cover the part.
No. The LG linear-compressor class-action settlement concerned cooling failures caused by the linear compressor itself, not ice maker failures. Ice maker hardware is separate, so a failed ice maker is repaired on its own.
Most LG ice maker repairs are 60–90 minutes on-site. Craft Ice module replacement is 75–90 minutes. We carry common ice maker parts on the truck, so many calls finish on the first visit.
Yes — OEM LG dual-coil inlet valves, ice maker modules, Craft Ice modules (revised), auger motors, fill tubes, and ice-room thermistors are all stocked. We do not use aftermarket parts on warranty repairs.
LG ice makers typically last 7–10 years before the first major repair. Hard water in west-metro suburbs (Plymouth, Eden Prairie, Minnetonka) can shorten that because mineral buildup clogs fill tubes and wears auger seals.
Yes — every LG ice maker repair includes a 1-year written parts-and-labor warranty. Same failure within 12 months, we come back free.
Many LG French-door refrigerators keep the ice maker in the door of the fresh-food compartment rather than in the freezer. That frees up freezer space, but it creates a problem the cabinet has to solve: the ice maker sits in a compartment that is naturally warmer than a freezer, so it needs a dedicated supply of cold air to freeze water into cubes. LG routes that air through ducting that runs up the cabinet side wall to ports that line up with the ice compartment when the door closes, with a fan to move it.
That design explains most of the odd LG ice complaints. If the duct is blocked by frost, the fan slows, or the compartment seal leaks, the ice maker cannot get cold enough. You see slow ice, soft cubes, cubes stuck together, or frost inside the ice compartment. The ice maker itself may be working perfectly while the air supply is what is failing.
It also explains why LG ice problems often follow door behavior. A door left ajar, a shelf bin that props it open, or a gasket that no longer seals will warm the compartment, melt the cubes and send meltwater into the ducts, where it refreezes. A tech who treats this as a pure water problem will replace a valve and the trouble will come back in a month.
Water and air problems feel alike from the kitchen. These clues help separate them.
Moisture is getting in or the cold air path is blocked. Frost inside the compartment is a gasket, seal or duct clue, not a fill clue.
The compartment warmed enough to melt them and cooled again. Look for a gap in the door seal and check that the door closes fully.
A whirring that has changed, or a fan that has gone quiet, can mean the ice compartment fan has begun to fail or ice has locked it.
Higher kitchen humidity and warmer air put more load on the seal and the cold air path. A system that coasts through winter shows weaknesses in July.
Water is reaching the fridge, so look at the air path and the mold temperature before you replace valves.
LG uses more than one ice-making layout. Which you own changes the checks.
| Layout | What it relies on | Typical weak spot |
|---|---|---|
| In-door ice maker on French-door models | Cold air ducted up the cabinet side wall to ports that meet the ice compartment when the door closes, plus a fan | Frost in the duct, a worn door seal, a fan that slows |
| Freezer-mounted tray | The freezer's own temperature | Valve flow, fill tube freeze, warm freezer |
| Craft Ice round-cube system | A slower, motorized freezing cycle in the freezer | Patience: it makes ice slowly, and a full tray is slower to rebuild |
| Models with an Ice Plus or boost setting | A temporary colder freezer for a faster batch | Leaving boost on can frost the compartment |
Craft Ice makes ice more slowly than a standard tray by design. If the bin is light after a party, give it a day before assuming a fault.
LG sells replacement filters under part names like LT1000P and LT700P. They are not interchangeable between models, and the wrong cartridge can leak at the head or restrict flow, which makes weak ice. Match the filter to the model number on the label inside the fridge. A genuine or properly certified cartridge also ensures the fridge reads the filter status correctly.
In the Twin Cities, hard water adds scale to the valve, the fill tube and any seals, and a cold house adds a second problem. An LG against a cold exterior wall in a drafty kitchen will chill its door and hinge area, which affects the ice compartment seal. We see this most often in older homes in south Minneapolis and St. Paul where kitchen walls are thinly insulated, and in additions where the fridge sits next to a mudroom door.
Basement and garage use deserves its own caution. LG French-door fridges are designed for room temperature, and a garage that drops below freezing can leave the compressor idle for long periods. Ice trouble in that setting is an environment issue first. For a wider look at LG water leaks, see our LG ice maker leaking page.
Make sure nothing props the door open. A bin full of tall bottles can hold it a fraction open, which is enough to warm the compartment.
The panel may have ice turned off or a boost mode on. Turn the boost off and let the unit run for a day.
A fresh cartridge and a couple of gallons through the dispenser clears air and sediment.
A dirty or sticky seal does not close well. Warm water and a soft cloth are enough.
Plastic ducts and fans are easy to crack. Unplug the fridge and let the frost melt on towels instead.
Ice maker repairs are usually sensible on an LG that is otherwise cooling well. If a unit has had repeated cooling faults or you are considering the ice maker as one of several repairs, the picture changes. Our LG refrigerator repair cost guide shows what common fridge repairs run, and the page on LG ice maker replacement explains when swapping the whole module is the better option.
On the visit we check airflow and the door seal as well as the valve and the module, then explain what we found. The $149 trip fee is credited toward the repair when you approve it, and all work carries our 1-year written parts-and-labor warranty. For other LG problems, see our LG appliance repair hub.
Ice makers refill a bin gradually, and the Craft Ice system is slower by design. Give it 24 hours, and use the boost mode if your model has one, then turn it off afterward.
A light, dry frost can form at the edges. Thick frost or ice that blocks the fan or duct is not normal.
Not usually, but it can reset the settings and melt cubes into a lump. Check the ice setting and clear any frozen mass once power returns.
Only if you do not need ice. It stops production without affecting the rest of the fridge. Remember to turn it back on.
Prices depend on the diagnosis and the part. We quote in writing before any work, so you know the cost before you approve it.
