LG LTCS24223D: Ice Maker Overflow and Freeze-Up in Memorial, TX
π Call (346) 512-3688π§ Performed by Serhii T.

The Problem
- β’Ice maker stopped producing ice entirely
- β’Ice bin filled with a solid block of frozen water instead of individual cubes
- β’Ice maker housing flooded and frozen solid with standing water
- β’No ice dispensed despite water supply being connected and active

π Diagnosis
When I arrived at the home in the 77079 zip code near Katy, the customer reported the LG LTCS24223D had not produced ice in several days. I pulled the ice bin and found it completely packed with a solid mass of frozen water. The ice maker module itself was also flooded and frozen, with ice formed around the fill cup and tray assembly. This is a classic overfill failure where the ice maker's internal water level sensor or fill timer loses calibration and allows the water inlet valve to deliver too much water per cycle. Before condemning the water inlet valve, I inspected it closely for calcium deposits and mineral buildup, which are common in Houston's water supply and cause valves to stick open. The valve membrane and ports were clean with no visible scaling, so I ruled it out as the primary cause. This LG LTCS24223D was manufactured in 2017, putting it at roughly nine years of service. At that age, the ice maker's internal control board and thermistor degrade and lose the ability to properly time the fill cycle. The result is exactly what I found: the valve opens, the ice maker module fails to signal it to close at the right moment, and the tray and bin flood. I confirmed the water inlet valve was functioning correctly by monitoring the fill cycle after installing the new ice maker module. The valve shut off precisely on time with no overfill observed.

π§ The Repair
- βStep 1: Pulled the ice bin and documented the frozen water mass filling the entire bin cavity and ice maker housing with photos.
- βStep 2: Disconnected power to the LG LTCS24223D at the wall outlet before beginning disassembly.
- βStep 3: Removed the frozen ice block from the bin by hand and cleared residual ice from around the ice maker mounting bracket using a plastic scraper to avoid damaging the liner.
- βStep 4: Disconnected the wire harness connector from the existing ice maker module and removed the three mounting screws securing the assembly to the freezer wall.
- βStep 5: Inspected the water inlet valve at the rear of the unit for calcium scaling and mineral deposits on the diaphragm and inlet ports. Found the valve clean and functioning within spec, so I left it in place.
- βStep 6: Installed the replacement LG ice maker module, secured the mounting screws, and reconnected the wire harness.
- βStep 7: Restored power and initiated a manual fill cycle by activating the test mode on the new ice maker module to observe the water inlet valve behavior in real time.
- βStep 8: Confirmed the water inlet valve opened, delivered the correct water volume, and closed without overfill. Freezer holding 0Β°F at close of visit. Customer advised to expect the first full ice production within 24 hours.

β Result
The new ice maker module was installed and tested on the same day as the first visit. The fill cycle completed correctly with no overflow, and the freezer was holding 0Β°F at the time I left. I advised the customer to check the bin at the 24-hour mark for the first batch of cubes. The water inlet valve was confirmed clean and left in service, which kept the repair cost down without cutting corners. The customer in Memorial was relieved to have a same-day resolution after days without ice.
π‘ Technician Notes
LG ice makers in the LTCS24223D and similar models from the 2015 to 2018 production window have a known pattern of overfill failures around the eight to ten year mark. The first sign you'll notice before a full freeze-up is smaller than normal ice cubes or cubes fused together at the bottom of the bin. That means the tray is already overfilling slightly on each cycle. If you catch it there, you have a short window before the bin floods entirely. In Houston, the water inlet valve takes more wear than in other cities because of mineral content in the local water supply. Every year or two, pull the ice bin and look at the fill cup for scale buildup. A white crust forming inside the cup is your signal to have the valve inspected before it causes a bigger problem. If your LG ice maker stops producing ice, do not run the refrigerator for days hoping it self-corrects. A flooded and refrozen bin can stress the ice maker housing and the bin itself. Call for service within 24 to 48 hours of noticing the problem.
Frequently Asked Questions
Why did my LG LTCS24223D ice maker fill up with water and freeze solid?
The ice maker module on the LG LTCS24223D loses its ability to time the fill cycle correctly as it ages. After around eight to ten years, the internal control board stops signaling the water inlet valve to close at the right moment. Water overfills the tray, spills into the bin, and freezes into a solid block. Replacing the ice maker module corrects this immediately.
How much does it cost to replace an ice maker on an LG refrigerator in Houston?
An LG ice maker module replacement in the Houston area typically runs between $180 and $320 depending on the specific model and whether the water inlet valve also needs replacement. For the LTCS24223D with a clean valve, replacing only the ice maker module keeps the cost at the lower end of that range. Same-day service is available in most Memorial and Katy area zip codes.
What happens if I ignore a frozen ice maker on my LG refrigerator and keep using it?
If the ice maker on your LG LTCS24223D is left flooded and frozen, the expanding ice block puts pressure on the bin walls and the ice maker housing. The bin can crack. In some cases the ice mass grows large enough to interfere with the freezer door closing fully, which raises temperatures throughout the refrigerator. Address a flooded ice maker within 24 to 48 hours.
Should I repair or replace my 2017 LG LTCS24223D if the ice maker failed?
A 2017 LG LTCS24223D with only an ice maker failure is a strong candidate for repair. The refrigeration system, compressor, and cabinet on this model are separate from the ice maker module. If the compressor and sealed system are running well, replacing only the ice maker module extends the useful life of the appliance at a fraction of the cost of a new refrigerator. Replacement makes more sense if multiple major components fail at the same time.
Do I need to replace the water inlet valve when the ice maker is replaced on an LG refrigerator?
Not always. The water inlet valve on an LG LTCS24223D should be inspected for calcium deposits and tested during the replacement visit. If the valve membrane is clean and the valve closes correctly during the post-installation fill test, it does not need to be replaced. In Houston's water conditions, valves do scale up over time, so inspection is always worth doing rather than assuming the valve is fine.
