LG LMXC23796D/00 bottom-mount refrigerator Parts

On LG model LMXC23796D, ice collecting at the bottom of the freezer is most often caused by a defrost drain that is partially or fully blocked; defrost water cannot flow to the drain pan, so it refreezes into a sheet of ice. Use the steps in the LMXC23796D manual to safely access and clear the drain area.

• Unplug the refrigerator before working in the freezer.
• Remove the freezer drawer and bins so you can see the floor of the freezer.
• If you see a solid ice “plate,” manually defrost it (door open, towels down) until you can access the drain area.
• Check for food packaging, ice chunks, or debris blocking the drain opening.
• After clearing visible blockage, flush the drain with warm water (small amounts at a time) to confirm it flows.

1. Clogged defrost drain: Water backs up and freezes on the freezer floor.
2. Drain tube restricted or iced over: Even if the drain hole looks clear, the tube can be blocked lower down.
3. Door not sealing well: Warm, humid air enters and increases frost, which can overwhelm normal defrost drainage.
4. Frequent door openings or overpacked freezer: Reduces airflow and increases moisture load.

If the drain keeps clogging or you find the tube damaged, the drain tube assembly is the most directly related service part for this symptom.

• Refrigerator drain tube assembly 5251JA3004E

When defrost water cannot drain properly, it refreezes and can eventually interfere with drawer operation, airflow, and temperature stability. Clearing the drain early helps prevent repeat icing and protects stored food.

Common problems we see on the LG LMXC23796D bottom-mount refrigerator include uneven cooling (fresh food warms while the freezer stays cold), slow or no ice production, and water dispensing issues. These symptoms are often tied to airflow blockages, temperature sensing, or filter and water-supply conditions; see the LMXC23796D manual for model-specific operating and troubleshooting steps.

• Fresh food section too warm but freezer is cold
• Frost buildup or restricted airflow near vents
• Ice maker not making enough ice or not dispensing
• Water dispenser flow is slow
• Interior moisture or condensation

Start with these no-tools checks before replacing parts:

• Confirm the doors close fully and gaskets seal all the way around.
• Make sure air vents are not blocked by food packages.
• Verify the temperature settings; typical defaults are 37°F for the refrigerator and 0°F for the freezer.
• Allow up to 24 hours to stabilize after installation, moving, or a power outage.
• If water or ice is affected, confirm the shutoff valve is fully open and water pressure is adequate.

If the basic checks do not help, these model-compatible parts are often involved:

• Refrigerator temperature sensor 6500JB2002E (thermistor): can cause incorrect temperature readings and uneven cooling.
• LG lt1000p refrigerator water filter ADQ74793501: a restricted filter can reduce water flow and ice production.
• LG refrigerator air filter ADQ73214408: helps control odors; not a cooling fix, but often replaced during maintenance.

Uneven cooling and restricted airflow can lead to food spoilage in the fresh food section and force the compressor to run longer than necessary, increasing wear and energy use.

LG model LMXC23796D does not use one single, universal “reset button.” Most resets are done by either power cycling the refrigerator, using a specific control-panel button sequence (such as exiting Display Mode), or resetting a specific feature like the water filter indicator. For model-specific button functions, use the LMXC23796D owner's manual.

• Power reset (general reset): Unplug the refrigerator, wait at least 5 minutes, then plug it back in.
• Water filter indicator reset: After replacing the filter, press and hold the Change Filter button for 3 seconds to turn the indicator off.
• Fresh air filter indicator reset: After replacing the air filter, press and hold the Fresh Air Filter button for 3 seconds to reset the indicator.
• Exit or enter Display Mode (store mode): With a refrigerator door open, press and hold Refrigerator and Ice Plus together for 5 seconds.

If the symptom returns quickly after a reset, we treat that as a troubleshooting clue. Common examples:

• Water flow stays weak after a filter change: the filter may be restricted or the inlet valve may be failing.
• Ice production problems continue: check the icemaker and water supply conditions.
• Odors return fast: the air filter may be overdue.

Helpful model-matched parts to consider:

• LG lt1000p refrigerator water filter ADQ74793501 (water filter replacement)
• LG refrigerator air filter ADQ73214408 (fresh air filter replacement)

Using the correct reset method on LMXC23796D prevents unnecessary part swaps and helps you pinpoint whether the issue is a setting (like Display Mode), routine maintenance (filters), or a component problem.

On our LG LMXC23796D refrigerator, “FDH” is not defined in the model’s owner’s manual, and LG display abbreviations can vary by control version. Use the LMXC23796D owner’s manual to confirm whether you’re seeing a status message or an error, then troubleshoot based on the symptoms (cooling, frost, fan noise).

Before troubleshooting, capture the exact display and conditions.

• Note the exact characters (FDH vs F dH vs dH) and whether it flashes
• Check if the refrigerator and freezer temperatures are holding steady
• Look for heavy frost on the rear freezer panel (airflow restriction)
• Listen for the evaporator fan running normally (no grinding or stopping)
• See if the message clears after a brief power reset

These steps help rule out common causes without assuming a specific code definition.

• Make sure both doors close fully and the gaskets seal all the way around
• Avoid blocking interior air vents with food packages
• If the unit was recently installed or moved, allow up to 24 hours to stabilize
• Power reset: unplug (or switch off the breaker) for 5 minutes, then restore power

Even though “FDH” itself isn’t defined for LMXC23796D in the manual, frost buildup plus poor cooling often points to a defrost or airflow problem. Common areas to inspect include the defrost heater, temperature sensor, wiring connections, and control.

• Defrost heater circuit (heater and wiring)
• Temperature sensing (thermistor)
• Evaporator fan and air passages
• Door seal leaks causing excess moisture

When frost blocks the evaporator, airflow drops and the fresh-food section can warm up even if the freezer seems cold. Addressing airflow and defrost issues early helps protect food and reduces compressor run time.
