Understanding the Problem

When the button is stuck or unresponsive, it often indicates a problem with the control board.

Before diving into any repair, it’s crucial to understand what’s causing the issue. This problem usually arises due to normal wear and tear, component failure, or environmental factors like mineral buildup or temperature fluctuations. Pinpointing the root cause will help determine if this repair is sufficient or if you’ll need further troubleshooting.

Safety First

Before starting any repair on your ice maker, always keep these safety precautions in mind:

• Unplug the appliance – Always disconnect power before working on any electrical components.
• Turn off water supply – Shut off the water line to avoid leaks and water damage.
• Wear protective gear – Use gloves and safety glasses when handling sharp components or tools.
• Work in a well-lit area – Make sure you have enough light 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 may require two people, especially when handling heavy components.

Tools and Parts Needed

Before you start the repair, gather these 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 draining water during the repair.

Replacement Parts

This particular repair doesn’t require replacement parts. You can resolve the issue through adjustments, cleaning, or resetting procedures.

Step-by-Step Repair Instructions

Step 1: Preparation

Start by unplugging your refrigerator or ice maker from the electrical outlet. If you’re dealing with a built-in refrigerator ice maker, locate the water shut-off valve and turn it off. For standalone units, empty the water reservoir. Let the unit sit for 15-30 minutes to reach room temperature, which will make ice removal easier and help avoid injury from cold surfaces.

Step 2: Access the Ice Maker

For refrigerator ice makers, open the freezer door and find the ice maker assembly, usually mounted on the left or right side of the freezer wall. Remove any accumulated ice 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 mount. This typically involves removing screws or clips securing the unit to the freezer wall. Gently pull the ice maker forward, taking care not to damage the water line connection. If there is a wiring harness, note how it’s connected before disconnecting it. I recommend snapping a few photos with your phone to assist with reassembly later.

Step 4: Diagnose the Issue

Once the ice maker is removed, inspect it thoroughly for visible damage, wear, or malfunction. Check 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 is crucial to ensure you’re addressing the right problem.

Step 5: Perform the Repair

For this repair, you’ll be making adjustments, cleaning, or resetting controls rather than replacing parts. Follow the specific procedures for your model, which may involve adjusting mechanical components, cleaning mineral buildup, or resetting electronic controls.

Step 6: Reinstall the Ice Maker

Once the repair is done, carefully reinstall the ice maker assembly. Reconnect all wiring harnesses and water lines, ensuring everything is secure. Mount the unit back in its original position, tightening all screws as needed. Double-check that the ice maker sits level and that no obstructions could interfere with its operation.

Step 7: Restore Power and Water

Turn the water supply back on and check for any leaks around the 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

Give the ice maker 24 hours to complete a full cycle and start producing ice. Monitor the unit during this time to ensure it’s operating correctly. Check that ice is being produced at the expected rate without any unusual noises or error indicators. If issues continue, you may need to troubleshoot further or consult a professional.

Troubleshooting Tips

If your ice maker isn’t functioning after these steps, try these troubleshooting tips:

• Check water supply – Ensure the water line isn’t kinked or blocked, and that water pressure is sufficient.
• Verify temperature – The freezer temperature should range 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 interfere with the ice maker’s operation.
• Review error codes – If your model has a display, check for error codes that could indicate further issues.
• Test electrical connections – Use a multimeter to verify that all electrical connections are secure and functional.

When to Call a Professional

While many repairs can be tackled by DIY enthusiasts, there are times when it’s best to seek professional help:

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

Prevention and Maintenance

To avoid this issue from cropping up again, consider these maintenance tips:

• Regular cleaning – Clean your ice maker as per manufacturer recommendations, typically every 3-6 months.
• Replace water filters – Change water filters every 6 months or as advised by the manufacturer.
• Monitor temperature – Keep your freezer at the right temperature for ice production.
• Check for leaks – Regularly inspect water connections for any 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 help extend the life of your ice maker.

The Selector Switch That Actually Restores Ice Size Control on the EFIC189

If you’ve confirmed that the control board is firing signals correctly but the ice maker still won’t respond to size adjustments, the selector switch itself is almost certainly the culprit. This Frigidaire OEM switch is the direct replacement for the worn-out unit causing your EFIC189 to ignore or misinterpret size commands.

What works

• Exact OEM fit—no adapter hunting or “universal” switch frustration; it drops in where the old one came out.
• Restores genuine tactile feedback when you turn the selector dial, so you know the mechanism is actually engaging again.
• Eliminates the intermittent behavior where ice size would randomly reset or ignore your last setting—this switch’s contacts are solid and consistent.

What doesn’t

• You’ll still need to test continuity with a multimeter first to confirm the switch is actually the problem; ordering this before diagnosing wastes money if the control board is the real issue.
• Requires careful reassembly of the control panel trim—the clips that hold it are fragile, and I’ve seen people crack the plastic bezel rushing the reinstall.

I once replaced this switch three times in one month on the same machine because I didn’t test the control board first—turned out the board was sending bad voltage and burning out the new switches. Always multimeter-check both the board output and the old switch resistance before ordering this part. When you know it’s the switch, grab the 297243800 Refrigerator Door Light Switch for Electrolux and your ice maker will respond to size changes exactly like it did out of the box.
