An LG refrigerator ice maker not working traces to one of six causes, ranked by frequency. The most common: water inlet valve failure, ice maker assembly failure, and a clogged or recently changed filter. This guide covers all six causes, four reset methods, and a DIY-or-call verdict for each.
You open the freezer and the bin is empty. Again. The rest of the fridge is cold and the water dispenser works fine, but the ice maker has gone quiet. Our techs handle LG refrigerator ice maker not working calls dozens of times each month across Denver Metro Area, and the same six causes account for virtually every service visit. LG French Door and LG Side-by-Side are the most common models. Searching “LG fridge not making ice” right now? That pattern points to a handful of causes, most diagnosable in under ten minutes.
Decision tree for LG ice maker diagnostics. Causes 1 through 6 are detailed in the section below.
A standard LG ice maker runs a five-step cycle. Water flows through the inlet valve and fills the ice mold. After freezing, a heater warms the tray to release cubes, and the ejector arm sweeps them into the ice bin. Freezer temperature, set by the freezer evaporator and circulation fan, drives the whole production cycle, so a failing fan motor stops ice even when the ice maker module is healthy.
LG sells three ice maker variants. The standard tray-style unit covers most French Door and Side-by-Side models manufactured from 2010 onward. Craft Ice appears on InstaView French Door refrigerators from 2019 onward, producing spherical ice at a slower rate by design. Some premium models carry a dual ice maker, one in the freezer and one in the door. LG refrigerator not making ice on any of these three follows the same six-cause ranked order.
The water inlet valve is a solenoid-controlled gate that opens when the ice maker module signals a fill. On some LG models, a split water inlet valve has separate solenoid branches for the dispenser and the freezer unit. A working dispenser does not rule out a valve problem. When the ice-side solenoid burns out, the dispenser flows while the mold stays dry.
Partial failure is more common than complete burnout. The coil weakens, water reaches the mold too slowly, and the result is LG refrigerator ice maker not making ice cubes of full size. LG valves require a minimum 20 PSI household water pressure to open fully, and low pressure causes partial fill without any hardware failure at all.
The ice maker module controls the entire cycle. LG sells the assembly as a complete unit: module, mold, and ejector arm. Board-only replacement is not supported because LG integrates the control circuitry directly into the assembly housing. Failure rates climb significantly at year five through eight. The fridge stays cold, water reaches the valve, but the mechanism stops advancing.
Press the Test button and hold for three seconds. A working unit beeps or the arm rotates through a harvest cycle. No response after a proper reset means the module has failed. LG fridge ice maker stopped working at year five or six is the classic profile across Denver Metro Area, and our techs see it repeatedly on French Door models in that age bracket.
Two filter scenarios stop ice. A clogged filter past the six-month cycle restricts flow below the pressure the inlet valve needs. After a replacement, LG requires a 24 to 48 hour air purge cycle before ice resumes. LG ice maker stopped working after filter change is expected behavior, not a hardware problem.
Install the bypass plug to confirm the filter is the cause. If ice resumes with the bypass plug installed, you have a confirmed filter restriction, and the repair is a standard replacement.
LG ice maker production stops above 10 degrees F as a built-in design feature, not a failure. Place a thermometer in the freezer for 30 minutes with the door closed. LG’s factory default is 0 degrees F. If it reads above 10 degrees F, ice stops by design. On LG SmartThinQ refrigerators from 2018 onward, the LG ThinQ app shows Ice Maker status before you open the freezer.
Upstream causes of a warm freezer include a failing door gasket, dead fan motor, defrost heater failure, or a compressor issue, each requiring a separate diagnostic before you touch the ice maker. LG refrigerator ice maker keeps freezing up is a separate symptom: fill tube icing from a disrupted defrost cycle, not temperature, and it resolves differently than a warm-freezer stop.
A reset resolves roughly 10% of calls without any part replacement. Demo mode disables both cooling and ice making on LG refrigerators and is often active on recently installed or transported units where the delivery team skipped the activation step. A ThinQ app glitch on LG SmartThinQ models can disable the ice maker through a software state, and a control board soft fault after a power outage stops production entirely without any physical component damage.
LG fridge ice maker not working after power outage resolves with a five-minute power cycle. Unplugging for five full minutes clears the fault without any part replacement.
A frozen fill tube blocks water even when the valve functions. Ice bridges form at the fill tube entry when the defrost cycle is disrupted. A five-minute reset often clears the bridge by triggering defrost. An ejector arm frozen in place is resolved by the reset button. A physically bent ejector arm requires assembly replacement.
A bridged bin is frequently mistaken for an ice maker failure. Ice fuses solid, the sensor reads full, and production stops. Remove the bin, break the bridge, reinstall. LG ice maker not dispensing ice is the symptom when the bin is bridged or the auger is jammed, and the fix takes under five minutes without any tools.
Most LG Craft Ice complaints come from an expectation gap, not hardware failure. When owners search “LG craft ice not working,” the unit is often meeting its rated output. Three spheres per 24 hours is the rated output for every Craft Ice model. The machine produces correctly when owners expect continuous supply.
When Craft Ice genuinely fails, the mold actuator motor is the most common cause. We see Craft Ice actuator failures most often on LG InstaView units past year four, particularly on models used in households with frequent door cycling. Hold the Craft Ice button for three seconds to turn it off, wait 30 seconds, then hold again to turn it on. Allow 24 hours. If LG ThinQ shows Craft Ice as On but no sphere appears, the actuator has likely failed.
LG ice maker not working on any Craft Ice model follows the same reset sequence. Many LG ice maker not making ice after reset cases resolve at Method 1 or 2. On LG French Door, LG Bottom Freezer, and some LG Side-by-Side models, Method 1 is fastest. If all four methods fail, the cause is hardware.
LG test/reset button location varies by model: underside of module on French Door and Bottom Freezer, front panel on some Side-by-Side models. Press and hold the Test button for three seconds with the fridge powered. A functional module beeps or the ejector arm rotates through a harvest cycle. No response indicates module failure.
Reset button locations vary by LG model. Left: French Door and Bottom Freezer (underside of module). Right: some Side-by-Side models (front panel).
Turn the ice maker off using its dedicated toggle, wait 30 seconds, turn it back on. This clears minor software states in seconds and costs nothing. Try it before the Test button on any LG model, because it resolves the most common software-glitch stops without any physical intervention.
LG ThinQ app provides a remote ice maker on/off toggle and error code history on 2018-plus smart fridges. Open the app, select your refrigerator, navigate to Ice Maker settings. Toggle off, wait 30 seconds, toggle back on. Use it as a free first diagnostic step on any LG SmartThinQ model before physical repairs.
Unplug the refrigerator or trip the circuit breaker. Wait five full minutes for capacitors to discharge. Restore power. Allow 24 to 48 hours for production to resume. LG fridge ice maker not working after power outage resolves with this method in most cases, and it is the single most effective reset for post-outage and post-move stoppages.

For standard LG models under 10 years old, repair is almost always the right call. The repair or replace decision shifts at 15 years: weigh repair cost against replacement if the issue involves a compressor. LG Craft Ice, LG InstaView, and LG Door-in-Door models are premium refrigerators where repair makes sense even at higher ages because their replacement cost is significantly higher than standard models.
If the fridge also runs warm in the fresh-food section, our guide on LG fridge not cooling covers the upstream causes. Both problems often share a single fix.

Six causes ranked by frequency: valve failure (30%), assembly failure (25%), clogged or recently changed filter (15%), freezer above 10 degrees F (15%), reset or demo mode issue (10%), and minor mechanical jams (5%). Start with the filter and reset checks before calling a technician.
Four methods work: toggle the on/off switch off for 30 seconds, then back on. Press and hold the Test button for three seconds. Use the LG ThinQ app to toggle the ice maker off and back on. Unplug for five full minutes to power-cycle the board. Allow 24 to 48 hours before concluding any reset failed.
After a filter change, LG requires a 24 to 48 hour air purge cycle before ice resumes. Air trapped in the housing disrupts flow during this window. LG ice maker stopped working after filter change is expected behavior, not a failure. Run 2 to 3 gallons through the dispenser right after installation to cut the purge to 2 to 4 hours.
LG Craft Ice makes three spheres per 24-hour cycle by design, not malfunction. When Craft Ice truly fails, the mold actuator is the most common cause. Hold the Craft Ice button for three seconds to turn it off, wait 30 seconds, then hold again to turn it on. Allow 24 hours. No sphere after a full day means the actuator has likely failed.
A standard LG ice maker produces its first ice roughly 24 hours after startup or a full reset, then runs at approximately 120 cubes per day. LG Craft Ice produces three spheres per 24-hour cycle on a separate schedule. No ice within the first few hours after reset is not yet diagnostic of a failure. Wait the full 24 hours.
Press and hold the Test button for three seconds to force a harvest cycle. If the ejector arm rotates, the mechanism works and the problem is a bridged bin. If the arm does not move, the arm is stuck or the assembly has failed. A physically bent ejector arm means full assembly replacement. LG ice maker not dispensing ice resolves at one of those two points.
Fully DIY: all four reset methods, the dispenser flush after a filter change, the thermometer test, and clearing a bridged bin. Valve replacement is manageable for homeowners comfortable with plumbing and basic electrical work. Assembly replacement carries model-mismatch risk. Call Wilson & Myers when the solenoid reads open circuit or the Test button gets no response.
Filter replacement costs only the filter itself. Valve replacement falls in the lower range of appliance repair costs. Full assembly sits in the moderate range. Compressor or sealed-system work runs higher. Wilson & Myers provides a firm quote before any work begins. Book through our ice maker repair service page for an estimate.
