LG Refrigerator Not Making Ice in the Twin Cities

LG Specialist

LG icemakers fail in 5 distinct patterns — and which one you have depends on whether you've got the in-door icemaker (LFXS / LMXS), the Craft Ice slow-melt round-cube maker (LRMVS / LRFVS / LRFXC), or the standalone freezer icemaker. We diagnose by symptom, not by guess.

Quick answer

LG Refrigerator Not Making Ice: the short answer

LG fridge not making ice usually narrows to: (1) frozen fill tube on the in-door icemaker — most common, easy fix; (2) failed Craft Ice motor on LRMVS / LRFVS / LRFXC models; (3) failed inlet valve, sometimes from mineral buildup; (4) failed icemaker assembly; or (5) main board / linear-compressor issue masking as no-ice. Most LG ice maker repairs land $215–$485 all-in. LG's warranty covers the linear compressor part for 10 years on most models, and we help with the LG parts claim. The flat $149 trip fee is credited toward the repair when you approve it. 1-year written warranty.

Common causes

Common failures

1. Frozen fill tube (most common — in-door icemaker)

What it is: On LFXS / LMXS / LSXS French-door and side-by-side models, water freezes in the white plastic fill tube where it crosses the mullion into the icemaker. Icemaker runs but no water arrives, eventually shuts down with a fault.

Fix: Steam the fill tube clear, then address the root cause — usually a low fridge-compartment temp setting or a worn icemaker fill cup seal that lets cold air migrate into the fill path.

Typical all-in: $215–$315 all-in

2. Craft Ice motor failure (LRMVS / LRFVS / LRFXC)

What it is: The Craft Ice slow-melt round-cube maker on 2019+ LG fridges uses a dedicated drive motor that can fail before the rest of the icemaker does. Regular cubes still drop; Craft Ice drawer stays empty. This is a common failure on these models.

Fix: Replace OEM Craft Ice motor assembly. About a 90-minute repair. Out-of-warranty units are quoted in writing; in-warranty (1-yr full or extended) parts and labor covered.

Typical all-in: $325–$485 all-in (out of warranty)

3. Failed water inlet valve (hard-water driven)

What it is: Mineral scale from hard water can build up on the inlet-valve diaphragm; water hardness varies by city and well. The valve doesn't open fully and the icemaker fills partially or not at all. Often presents as small / hollow cubes before going dead.

Fix: Replace OEM dual-coil LG inlet valve. Always paired with a new water filter and a clean line flush.

Typical all-in: $245–$345 all-in

4. Failed icemaker module / harvest motor

What it is: The icemaker module itself fails — thermistor, harvest motor, or control. The module runs LG's own diagnostic via a fill-test switch; failure modes are clear under test.

Fix: Replace OEM LG icemaker assembly. About 45–60 min on the truck.

Typical all-in: $285–$425 all-in

5. Linear-compressor / main-board failure masking as no-ice

What it is: If the freezer can't hold below 5°F the icemaker stops making ice as a secondary symptom. Sometimes an LG linear compressor or inverter board problem (Er CO is the compressor fault code) is the real issue. Check freezer temp at a known-good thermometer before any icemaker work.

Fix: If sealed system, we help with the LG 10-year compressor warranty claim (you pay labor, $485–$785). If main board, OEM board replacement quoted separately.

Typical all-in: Quoted after diagnosis — see LG linear compressor page

Diagnostic order

How to diagnose an LG refrigerator that won't make ice

  1. 1. Confirm the freezer is below 5°F

    Put a thermometer in the freezer and check after 30 min. If above 5°F, the icemaker is shutdown because of temperature — fix the cooling problem first (often linear compressor).

  2. 2. Listen for the harvest cycle

    Watch the icemaker for 90 minutes. A healthy LG icemaker harvests every 90–180 min. No harvest motion = module fault. Harvest motion + no water = inlet valve or fill tube.

  3. 3. Check the fill tube for ice

    Pull the icemaker and look up into the fill tube. Visible ice plug = melt with hair dryer (low heat, 5 min). Reseat icemaker, watch one harvest cycle.

  4. 4. Know when to stop

    If the fill tube is clear and the freezer is cold, stop here. Testing the inlet valve means working at the rear panel with power on, so unplug the refrigerator and leave valve and electrical testing to a technician.

  5. 5. Run the Craft Ice test (LRMVS / LRFVS)

    On Craft Ice models, a technician can run the Craft Ice motor on its own. No motor sound points to an OEM Craft Ice motor replacement.

FAQs

LG Refrigerator Not Making Ice: FAQs

Why is my LG Craft Ice not making round cubes?

The Craft Ice slow-melt round-cube motor is a common early failure point on these models. Regular cubes will keep dropping; only the Craft Ice drawer stays empty. OEM motor replacement is about a 90-minute repair.

Is my LG fridge under warranty for the icemaker?

LG's standard warranty is 1 year parts and labor on the icemaker. The linear compressor carries 10 years sealed-system. If your no-ice symptom is from the compressor (Er CO), the part is usually covered and you pay labor ($485–$785). Have your model and serial number ready when you call.

How much does LG ice maker repair cost?

Most LG ice maker repairs run $215–$485 all-in: fill-tube thaw $215–$315, inlet valve $245–$345, icemaker module $285–$425, Craft Ice motor $325–$485. Linear-compressor work is quoted separately. The $149 trip fee is credited toward the repair when you approve it.

What LG models have the most icemaker issues?

LFXS and LMXS French-door 2014–2019 had high in-door icemaker failure rates. LRMVS / LRFVS / LRFXC 2019+ have the documented Craft Ice motor issue. Hard water can shorten the life of any icemaker inlet valve.

Can I fix the LG icemaker myself?

Fill-tube unfreeze, yes (hair dryer, low heat). Filter change, yes. Icemaker module, inlet valve, or Craft Ice motor replacement, no — they require proper electrical testing to avoid replacing the wrong part.

Do you carry LG icemaker parts on the truck?

Yes — OEM LG icemaker modules, inlet valves, fill-tube kits, and Craft Ice motors are stocked. Linear compressors are special-order. If your part isn't on the truck, we order it from the OEM distributor and schedule a return visit.
