🔍 Diagnosis / Cause Found
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.

🔧 Repair Performed
Step 1: Pulled the ice bin and documented the frozen water mass filling the entire bin cavity and ice maker housing with photos.. Step 2: Disconnected power to the LG LTCS24223D at the wall outlet before beginning disassembly.. Step 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.. Step 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.. Step 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.. Step 6: Installed the replacement LG ice maker module, secured the mounting screws, and reconnected the wire harness.. Step 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.. Step 8: Confirmed the water inlet valve opened, delivered the correct water volume, and closed without overfill. Freezer holding 0°F at close of visit. Customer advised to expect the first full ice production within 24 hours.

✅ 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 0°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.
