Understanding the Problem

Complete failure to produce ice; electronic control board or motor failure

Before diving into any repair, it’s vital to understand what’s causing the issue. This problem usually results from normal wear and tear, component failure, or environmental factors like mineral buildup or temperature fluctuations. Pinpointing the root cause will help you decide if this repair will fix your problem or if more troubleshooting is needed.

Safety First

Before starting any ice maker repair, always follow these safety precautions:

• Unplug the appliance – Always disconnect power before working on any electrical components
• Turn off water supply – Shut off the water line to prevent leaks and water damage
• Wear protective gear – Use gloves and safety glasses when handling sharp components or working with tools
• Work in a well-lit area – Ensure you have adequate lighting to see all components clearly
• Allow components to warm up – If working on freezer components, let them reach room temperature to prevent injury from cold surfaces
• Have a helper available – Some repairs require two people, especially when handling heavy components

Tools and Parts Needed

Before beginning this repair, gather the following tools and parts:

Essential Tools

• Phillips and flathead screwdrivers – For removing screws and accessing components
• Nut driver set – For removing hex nuts and bolts
• Pliers – Both regular and needle-nose pliers for gripping and manipulating small parts
• Multimeter – For testing electrical components and continuity
• Putty knife or plastic scraper – For removing ice buildup without damaging components
• Flashlight or work light – For illuminating dark freezer compartments
• Container for water – To catch any water that drains during the repair

You can find this replacement part at appliance parts stores, online retailers, or through the manufacturer. Always verify the part number matches your specific model before purchasing.

Step-by-Step Repair Instructions

Step 1: Preparation

Start by unplugging your refrigerator or ice maker from the electrical outlet. If you’re working on a built-in refrigerator ice maker, locate the water shut-off valve and turn it off. For standalone units, empty the water reservoir. Allow the unit to sit for 15-30 minutes to reach room temperature; this makes ice removal easier and prevents injury from cold surfaces.

Step 2: Access the Ice Maker

For refrigerator ice makers, open the freezer door and locate the ice maker assembly, typically mounted on the left or right side wall of the freezer compartment. Remove any ice that has accumulated around the unit. For standalone ice makers, take out the ice basket and any ice blocking access to internal components.

Step 3: Remove the Ice Maker Assembly

Carefully disconnect the ice maker from its mounting. This usually involves removing mounting screws or clips that secure the unit to the freezer wall. Gently pull the ice maker forward, being cautious not to damage the water line connection. If there’s a wiring harness, take note of how it’s connected before disconnecting it. Snap a few photos with your phone to help with reassembly.

Step 4: Diagnose the Issue

With the ice maker removed, inspect it thoroughly for visible signs of damage, wear, or malfunction. Look for cracked plastic components, damaged wiring, or signs of water damage. If you have a multimeter, test electrical connections according to the manufacturer’s specifications. This diagnostic step will confirm that you’re addressing the right problem.

Step 5: Perform the Repair

If you’re replacing a component, carefully remove the old part following the manufacturer’s instructions. Install the new 5989JA1005G replacement part, ensuring all connections are secure and properly aligned. Double-check that all screws are tightened appropriately – not too loose, but not so tight that you strip the threads.

Step 6: Reinstall the Ice Maker

Once the repair is complete, carefully reinstall the ice maker assembly. Reconnect all wiring harnesses and water lines, ensuring connections are secure. Mount the unit back in its original position, tightening all mounting screws. Verify that the ice maker sits level and that there are no obstructions to its operation.

Step 7: Restore Power and Water

Turn the water supply back on and check for any leaks around connections. Plug the appliance back into the electrical outlet. For refrigerator ice makers, close the freezer door and allow the unit to cool down. The ice maker should begin its normal cycle once the freezer reaches the proper temperature (typically 0-5°F).

Step 8: Test the Repair

Allow 24 hours for the ice maker to complete a full cycle and produce ice. Monitor the unit during this time to ensure it’s working correctly. Check that ice is being produced at the expected rate and that there are no unusual noises or error indicators. If the issue persists, you may need to troubleshoot further or consult a professional.

Troubleshooting Tips

If your ice maker still isn’t working after completing this repair, try these troubleshooting steps:

• Check water supply – Make sure the water line is not kinked or blocked, and that water pressure is adequate
• Verify temperature – Freezer temperature should be between 0-5°F for optimal ice production
• Inspect water filter – A clogged water filter can restrict flow and prevent ice production
• Check for ice buildup – Excessive ice accumulation can prevent the ice maker from operating
• Review error codes – If your model has a display, check for any error codes that might indicate additional issues
• Test electrical connections – Use a multimeter to verify all electrical connections are secure and functioning

When to Call a Professional

While many ice maker repairs can be tackled by DIY enthusiasts, there are instances where professional help is advisable:

• If you’re uncomfortable working with electrical components
• When the repair requires specialized tools or knowledge
• If the problem persists after following all troubleshooting steps
• When dealing with complex electronic control boards
• If you discover additional problems during the repair
• When the cost of parts approaches the cost of a new unit (for standalone ice makers)

Prevention and Maintenance

To prevent this issue from recurring, follow these maintenance tips:

• Regular cleaning – Clean your ice maker according to manufacturer recommendations, typically every 3-6 months
• Replace water filters – Change water filters every 6 months or as recommended by the manufacturer
• Monitor temperature – Keep your freezer at the optimal temperature for ice production
• Check for leaks – Regularly inspect water connections for signs of leaks or wear
• Descale regularly – In areas with hard water, descale your ice maker more frequently to prevent mineral buildup
• Use quality water – Using filtered or purified water can extend the life of your ice maker

The Genuine LG Ice Maker Assembly That Actually Solves the Problem

This is the part you need—there’s no workaround or troubleshooting that gets around it. The AEQ73110212 is the genuine OEM assembly, and on this model, it’s the only real fix when the motor, mold, or thermostat fails as an integrated unit.

What works

• Genuine part means exact fitment—no adapter brackets, no forced clips, no hoping the connectors line up close enough. It drops in where the old one came out.
• The thermostat and motor are calibrated to LG’s spec, so you don’t get the slow-cycle or freeze-up issues that sometimes happen with off-brand replacements.
• Warranty coverage—if it fails prematurely, you have recourse rather than discovering you bought a third-party clone with a 30-day return window.

What doesn’t

• Price is higher than compatible aftermarket assemblies, but you’re paying for the part that actually lasts and doesn’t create a second repair visit in 18 months.
• Availability can be tight depending on your retailer—I’ve had jobs delayed waiting for stock. Order early if you’ve already diagnosed the assembly as failed.

I’ve seen DIYers order a cheaper “compatible” assembly first, install it, and then deal with erratic cycling or no ice production—only to swap it back out for the genuine part. Don’t go that route. Get the genuine LG AEQ73110212 ice maker assembly the first time.
