Lg French Door Refrigerator Ice Maker Not Dumping Ice

ByJim Boslice Home & Kitchen

To fix an LG ice maker that won’t dump ice, start by pressing the test/reset button located on the bottom or side of the ice maker unit for 3 seconds. This forces a harvest cycle to clear software glitches or minor jams.

If the reset fails, ensure your freezer temperature is set to -4°F (-20°C) or lower, as the ice maker will not cycle if the internal sensor detects a temperature that is too warm.

We have all been there—reaching for a glass of cold water after a long day in the workshop only to find the ice bin completely empty. It is a frustrating experience, especially when you can see the ice sitting right there in the tray, refusing to budge. This common LG appliance hiccup can stall your workflow and leave you with lukewarm drinks.

You do not need to call an expensive appliance technician just yet or spend hundreds on a service call. Most reasons for an lg french door refrigerator ice maker not dumping ice can be diagnosed and repaired with basic hand tools and a bit of patience. Whether it is a software glitch or a mechanical jam, we can handle it.

Today, I am going to walk you through the exact troubleshooting steps I use to get my own garage fridge back in working order. We will cover everything from the hidden reset button to checking the mechanical ejector arms and water valves. Let’s dive into the guts of your refrigerator and get that ice flowing again.

The First Step: Forcing a Manual Harvest Cycle

Before you start tearing panels off, you need to determine if the problem is electrical or mechanical. LG ice makers come equipped with a test button that is designed specifically for this scenario. This button forces the motor to turn and the tray to twist or the fingers to eject.

Locate the small, recessed button on the bottom or side of the ice maker assembly, often hidden behind a small rubber flap. You may need a flat-head screwdriver or a paperclip to reach it depending on your specific model. Ensure the ice bin is in place or hold a bowl underneath to catch any falling cubes.

Press and hold this button for about three to five seconds until you hear the motor begin to hum. If the tray turns and dumps the ice, your motor is fine, and the issue likely lies with a sensor or temperature setting. If nothing happens at all, we are likely looking at a power issue or a dead motor assembly.

Troubleshooting an lg french door refrigerator ice maker not dumping ice

If the manual test did not solve the problem, we have to look deeper into why the lg french door refrigerator ice maker not dumping ice is occurring. One of the most frequent culprits is actually the ambient temperature inside the freezer compartment. If the sensor does not “see” a temperature low enough, it won’t trigger the dump.

Most LG units require the internal mold temperature to reach approximately 8°F to 12°F before the harvest cycle begins. If your freezer is set to 0°F, but the door is opened frequently or the seals are leaky, the ice mold might never get cold enough to trigger the ejector. Try lowering your freezer setting to -4°F for 24 hours.

Another common mechanical issue is ice bridging, where cubes melt slightly and refreeze into a single solid mass. This “bridge” prevents the ejector arms from pushing the ice out of the mold. If you see a solid block of ice in the tray, use a hair dryer on low heat to gently melt the obstruction, being careful not to warp the plastic parts.

Checking for Mechanical Obstructions

Just like a jammed table saw, a small piece of debris can stop the entire mechanism from functioning. Sometimes, a single malformed ice cube gets stuck under the ejector blades. When the motor tries to turn, it hits this resistance and shuts down to prevent burning out the motor.

Inspect the “fingers” or the tray for any signs of cracked plastic or stuck debris. If you find a cube wedged in there, do not use a metal pick to pry it out, as you might scratch the non-stick coating on the ice mold. Use warm water or a plastic spatula to gently dislodge the stuck ice.

The Role of the Feeler Arm

Many LG French Door models use a feeler arm or an optical sensor to detect when the ice bin is full. If this arm is stuck in the “up” position, the machine thinks the bin is overflowing and will stop dumping ice. Ensure the arm can move freely and isn’t blocked by a stray bag of frozen peas.

For models with optical sensors, look for two small “eyes” on either side of the ice bucket housing. If these lenses get covered in frost or “ice dust,” they can’t see each other. Simply wipe them down with a microfiber cloth and some warm water to restore the connection and allow the dumping process to resume.

Inspecting the Water Inlet Valve and Pressure

It might seem counterintuitive, but a problem with the water supply can lead to an lg french door refrigerator ice maker not dumping ice. If the water pressure is too low, the ice cubes produced will be smaller than usual. These “shrimpy” cubes often fail to engage with the ejector arms properly, causing them to stay stuck in the mold.

Check the water filter located inside your refrigerator; if it hasn’t been changed in over six months, it might be clogged. A clogged filter reduces pressure, leading to hollow or undersized cubes. Replace the filter and see if the next batch of ice is full-sized and able to dump correctly.

You should also inspect the water inlet valve at the back of the fridge. This is a solenoid-operated valve that controls the flow of water to the ice maker. If the valve is failing, it may not be providing enough volume to fill the tray, or it might be leaking slightly, causing a massive frost buildup that jams the dumping mechanism.

How to Test the Solenoid Valve

For the DIYers who are comfortable with a multimeter, you can test the solenoid for continuity. First, unplug the refrigerator to ensure your safety. Locate the valve at the bottom rear of the unit and disconnect the wire harness to check the resistance levels.

If the multimeter shows an open circuit (infinite resistance), the solenoid is dead and the entire valve assembly needs to be replaced. This is a straightforward “plug and play” repair that requires only a nut driver and about twenty minutes of your time. Always ensure the water supply is turned off before disconnecting the lines.

Dealing with Frozen Fill Tubes

In some cases, the fill tube—the small plastic pipe that delivers water into the ice tray—can freeze solid. When this happens, the ice maker continues its cycle, but no water enters the tray. The machine essentially “ghost cycles,” trying to dump air instead of ice.

If you see icicles hanging from the fill tube, you have a freezing issue. You can thaw this out using a turkey baster filled with hot water or a hair dryer. To prevent this from happening again, ensure your water pressure is at least 40 PSI, as low pressure allows water to trickle and freeze inside the tube.

Advanced Fixes: The Control Board and Motor Assembly

If you have checked the temperature, cleared the jams, and verified the water supply, the problem might be the main control board or the ice maker motor itself. The control board acts as the “brain” of the operation, sending the signal to the motor to begin the harvest cycle.

Sometimes, a power surge can fry a specific relay on the board that controls the ice maker. While you can’t easily repair the board itself, you can check for burnt components or “puffed” capacitors. If the board looks damaged, replacing it is often the only solution to fix an lg french door refrigerator ice maker not dumping ice permanently.

The motor assembly inside the ice maker unit can also wear out over time. If you hear a clicking or grinding noise during the test cycle, the internal gears are likely stripped. Since these units are usually sealed, you will need to replace the entire ice maker assembly, which is held in by just a few screws and one electrical plug.

Essential Tools for Ice Maker Repair

You do not need a specialized kit to fix these issues, but having the right tools on hand makes the job much smoother. Most of these are likely already in your garage workshop or tool chest. Here is what I recommend keeping nearby when you start the diagnosis:

  • Phillips Head Screwdriver: For removing the ice maker mounting screws.
  • Small Flat-Head Screwdriver: Useful for pressing the recessed reset button.
  • Hair Dryer: To safely melt frost or ice jams without damaging plastic.
  • Multimeter: For testing continuity on the water valve or thermal fuse.
  • Flashlight: To see into the dark corners of the freezer compartment.
  • Microfiber Cloth: For cleaning optical sensors and wiping away moisture.

Always remember the safety first rule of the workshop: if you are doing anything more than pressing a reset button, unplug the refrigerator. Working around water and electricity requires caution, and it only takes a second to pull the plug and ensure a safe working environment.

Maintaining Your LG Ice Maker for Longevity

Prevention is always better than a mid-summer repair. To keep your lg french door refrigerator ice maker not dumping ice from becoming a recurring headline in your home, perform a bit of routine maintenance. Start by cleaning the ice bin every few months to remove “ice snow” that can interfere with the sensors.

Check the door gaskets regularly for any gaps or tears. If warm, moist air leaks into the freezer, it creates excessive frost, which is the primary enemy of mechanical ice makers. A simple trick is to close the door on a dollar bill; if you can pull the bill out with no resistance, your seal is weak and needs cleaning or replacement.

Finally, keep your condenser coils clean. If the coils at the bottom or back of the fridge are covered in dust and pet hair, the compressor has to work harder, and internal temperatures can fluctuate. A stable, cold environment is the best way to ensure your ice maker stays in its rhythm and continues to dump ice reliably.

Frequently Asked Questions About lg french door refrigerator ice maker not dumping ice

How long should I wait after a reset for ice to dump?

After pressing the test button, the cycle happens immediately. However, if you have just performed a reset or replaced a part, it can take 24 hours for the unit to reach the proper temperature and resume a normal production schedule. Be patient and keep the door closed as much as possible.

Can a dirty water filter really stop ice from dumping?

Yes, absolutely. A clogged filter reduces water flow, leading to undersized cubes. These small cubes don’t have enough mass for the ejector arms to “grab” them effectively, or they can get stuck in the mold, eventually causing a total freeze-up of the dumping mechanism.

Why is there ice buildup on the ceiling of my ice room?

This is usually caused by a leaky air seal around the ice maker compartment. In French Door models, the ice maker is often in the refrigerator section, and it relies on a tight seal to keep the cold air in. If the seal is compromised, frost will build up and eventually jam the moving parts of the ice maker.

Should I use a de-icer spray on my ice maker?

No, you should never use chemical de-icers or sharp metal objects inside your refrigerator. These chemicals are not food-safe, and metal tools can puncture the cooling lines or ruin the non-stick surface of the ice mold. Stick to warm water and a hair dryer on a low setting for safe defrosting.

Getting Back to the Craft

Fixing an lg french door refrigerator ice maker not dumping ice is a rewarding DIY project that saves you money and restores a bit of convenience to your home. By following a logical troubleshooting path—starting with the easiest fixes like the reset button and moving toward mechanical inspections—you can solve 90% of these issues yourself.

There is a certain pride in being the person who can maintain the household appliances just as well as the projects in the woodshop.
