LG LFX25973ST/05 bottom-mount refrigerator Parts

For the LG LFX25973ST bottom-mount refrigerator, the compressor warranty is typically longer than the rest of the unit; common coverage is 10 years on compressor parts and 5 years on compressor labor. For the exact terms that apply to your serial number and purchase date, use the LFX25973ST owner’s manual.

Warranty coverage varies by component and by how the refrigerator is used and installed. In most cases, warranty coverage focuses on defects in materials or workmanship.

• Compressor coverage is often the longest term on the refrigerator
• Labor coverage can be shorter than parts coverage
• Cosmetic items, normal wear, and damage from installation issues are commonly excluded
• Proof of purchase date can affect what coverage applies
• Using non-approved parts or improper repairs can affect coverage

Use these steps to match the warranty to your specific LFX25973ST:

1. Check the warranty section in the LFX25973ST owner’s manual.
2. Match coverage by purchase date (receipt) and serial number.
3. Identify the failed component (for example, compressor, control board, ice maker, or water filter).

Warranty terms determine whether you should schedule service first or order parts first. For example, a sealed system issue may be covered differently than an ice maker or dispenser issue, and labor coverage can change the total out-of-pocket cost.

On the LG LFX25973ST, the bottom (freezer) ice maker is turned on by enabling ice production at the control panel and making sure the ice maker switch or Ice On setting is set to ON. After turning it on, allow up to 24 hours for the first full bin of ice.

• Confirm the refrigerator is plugged in and cooling normally.
• Open the freezer and make sure the ice maker power switch (if your unit has one on the ice maker) is in the ON position.
• On the dispenser/control panel, set Ice On (or Ice Maker) to ON.
• Make sure Ice Plus is optional; it can speed production but is not required.
• Verify the water supply valve behind the refrigerator is fully open.
• Dump the first batch of ice if the unit has been off for a while.

Most “ice maker off” issues come down to a setting, water supply, or a frozen fill path.

• Control lock: If Control Lock is enabled, turn it off and try enabling Ice On again.
• Water filter: A clogged filter can reduce flow and stop ice production; replace the LG refrigerator water filter ADQ72910911 if it is overdue.
• Air in the water line: Dispense water for 2 to 3 minutes to purge air.
• Freezer temperature: Set the freezer near 0°F; warmer temps slow or stop ice.
• Ice bin position: Make sure the bin is seated fully so the shutoff arm/sensor can work.

If the ice maker is left OFF or water flow is restricted, the ice maker can appear “bad” even though it is working correctly. Verifying the ON setting, water supply, and filter condition prevents unnecessary part replacement.

For model-specific control panel wording and the exact ice maker ON/OFF procedure, follow the LFX25973ST owner's manual.

On an LG LFX25973ST bottom-mount refrigerator, the “bottom part” most people mean is the compressor compartment area (the machinery section near the lower rear). The key component there is the compressor, which circulates refrigerant to keep the refrigerator and freezer cold.

Depending on what you are pointing to, the bottom area can refer to different parts:

• Compressor compartment: the lower rear service area where cooling components sit
• Freezer drawer: the bottom drawer section on a bottom-mount design
• Toe grille or base grille: the lower front cover (on some refrigerators)
• Condenser area: where heat is released (often near the bottom/rear)

These are the most common components located in the lower rear area:

• Compressor
• Condenser coil
• Condenser fan motor (on many models)
• Drain pan (for defrost water evaporation)
• Wiring harnesses and control components

If you are troubleshooting noise, warm temperatures, or poor cooling, these model-matched parts are commonly involved:

• Refrigerator compressor TCA38091801
• Refrigerator condenser coil ACG73784701

Using the right name helps you find the correct diagram and repair steps, especially when ordering LG refrigerator parts or describing a symptom like “buzzing at the bottom” or “not cooling.” For model-specific locations and access steps, use the LFX25973ST manual.

For the LG LFX25973ST refrigerator, the most reliable reset is a power reset: unplug the refrigerator (or switch the circuit breaker off) for 60 seconds, then restore power. This reboots the control board and often clears minor glitches after a power outage or control-panel freeze.

• Power reset (recommended): Unplug for 60 seconds, then plug back in.
• Breaker reset: Turn the refrigerator breaker off for 60 seconds, then back on.
• Control lock check: If the panel seems “dead,” make sure Control Lock is not enabled (some LG models disable buttons when locked).
• Filter indicator reset: Use the filter reset procedure shown in the LFX25973ST owner's manual.
• Ice maker reset: If ice production is the issue, follow the ice maker reset steps in the LFX25973ST owner's manual.

1. Move any perishable items to a cooler if you expect the unit to be off longer than a minute.
2. Unplug the power cord (or turn the breaker off).
3. Wait 60 seconds.
4. Restore power.
5. Allow 5 to 10 minutes for the control to stabilize; cooling performance can take several hours to fully recover.

A reset is a fast first step because it reboots the electronic control board and can restore normal operation without replacing parts. If symptoms return quickly, that points to an underlying issue such as airflow, temperature sensing, or an ice and water supply problem.

If you are troubleshooting ice or water issues after resetting, the how to replace the water filter in an LG refrigerator guide pairs well with this model’s filter maintenance.

Ice building up on the bottom of the freezer in your LG LFX25973ST almost always happens when the defrost drain is clogged or frozen; defrost water cannot flow to the drain pan, so it refreezes into a sheet of ice. Clearing the drain and fully defrosting the freezer stops the repeat icing.

• Unplug the refrigerator or turn off power at the breaker.
• Remove the freezer drawer/bins and look for a solid ice slab on the floor.
• Melt the ice with a hair dryer on low or by leaving the door open with towels (do not chip ice with sharp tools).
• Find the drain opening under/behind the rear freezer panel area and clear any ice or debris.
• Flush the drain with hot water using a turkey baster or squeeze bottle until it flows freely.
• Make sure the door closes tightly and nothing is holding the gasket open.

1. Empty the freezer and protect the floor with towels.
2. Remove the rear freezer panel (if accessible) to reach the drain trough.
3. Melt ice in the trough and around the drain hole.
4. Flush with hot water until you hear/see water draining to the pan underneath.
5. Reassemble, restore power, and allow 12 to 24 hours for temperatures to stabilize.

If the drain clears but refreezes repeatedly, we typically look for airflow or temperature-control issues that increase frost and overwhelm the drain.

A clogged defrost drain can cause recurring ice sheets, reduced freezer space, warmer temperatures, and water leaks when the ice melts. Fixing the drain protects food quality and helps the compressor run normally.

• Use our LFX25973ST manual for panel removal and compartment layout.
• Follow how to get rid of refrigerator puddles if you also see water under the refrigerator.
• Use how to fix your evaporator cooling fan if you suspect weak airflow or unusual fan noise.

If your LG LFX25973ST bottom-mount refrigerator is not making ice, the most common causes are a water supply problem, a frozen or blocked fill path, or an ice maker issue in the freezer compartment. Start with the water filter and basic ice maker checks in the LFX25973ST owner’s manual.

• Confirm the freezer is cold enough (target about 0°F); ice production drops fast above ~10°F.
• Make sure the ice maker is turned ON and the ice bin is seated correctly.
• Check the shutoff arm or sensor area for anything holding it in the “bin full” position.
• Replace an overdue or clogged water filter; use the correct LG refrigerator water filter ADQ72910911.
• Verify the household water supply valve is fully open and the water line is not kinked.
• Look for ice clumps in the bin; break up clumps and clear the chute area if needed.

A weak fill usually points to a restricted filter, low house water pressure, or a failing inlet valve.

If the freezer is warm or airflow is poor, the ice maker will not cycle normally.

Depending on what you find, these model-matched parts are often involved:

• LG refrigerator water filter ADQ72910911 (restriction is a top cause)
• Ice maker assembly (AEQ73110203) - refrigerator ice making component by LG AEQ73110203 (ice maker not cycling)
• Refrigerator evaporator fan motor 4681JB1027C (poor airflow can reduce ice production)

Ice production depends on three things working together: correct freezer temperature, steady airflow, and consistent water flow. Fixing the root cause prevents repeat clogs, ice jams, and slow ice making.

The most common problem we see with LG refrigerators like model LFX25973ST is a cooling problem: the fresh food section or freezer warms up, temperatures swing, or food spoils faster than normal. The next most common issues are ice maker and water dispenser problems, often tied to airflow, filters, or door sealing.

• Refrigerator section is warm but freezer seems OK (or the reverse)
• Unit runs a lot, or you hear frequent cycling
• Frost buildup on the back wall or around vents
• Weak airflow from the vents
• Unusual fan noise (especially after the door closes)

For model-specific operating tips and control settings, use the LFX25973ST owner's manual.

1. Confirm settings: fridge about 37°F, freezer about 0°F.
2. Check door seal and alignment: gaps or a twisted gasket cause warm air leaks.
3. Avoid blocked vents: keep packages from covering interior air returns.
4. Clean condenser area: dust buildup raises temps and run time.
5. Listen for the evaporator fan: it should run when the compressor is running (door switch closed).

If the door is not sealing well, a worn gasket is a common fix; for example, the refrigerator door gasket, right ADX73550627 is a listed option for this model.

For water and ice complaints, we often start with the filter; the LG refrigerator water filter ADQ72910911 is a common maintenance item.

Cooling and ice issues usually get worse over time. Catching airflow restrictions, a failing fan motor, or a leaking door seal early helps protect food, reduce energy use, and prevent heavy frost that can block circulation.
