How to Fix Your Kenmore Ice Maker When It Stops Working

Start with the simplest fixes first

Most Kenmore ice maker problems come from three things: a frozen water line, a stuck fill valve, or the ice maker being turned off by accident. Before you call for service, check whether the ice maker arm is in the up position (which stops it) or down position (which runs it). If the arm is down and ice still is not forming, feel the water line behind the refrigerator—if it is rock hard, that is your problem.

A frozen water line happens when the freezer temperature drops below 0°F or when cold air gets trapped around the line. You can thaw it by wrapping the line with a heating pad set to low, or by pouring warm (not boiling) water over it slowly. Once it thaws, ice should start forming within a few hours. If it freezes again right away, the freezer temperature is too low—raise it to between 0°F and 5°F.

Key Takeaways

• Check that the ice maker arm is in the down position and the freezer temperature is set between 0°F and 5°F before troubleshooting anything else.
• A frozen water line is the most common cause and can be thawed with a heating pad or warm water poured slowly over the line.
• The fill valve (the part that lets water into the ice maker) can jam from mineral buildup and may need to be replaced if thawing does not work.
• If water is leaking from the ice maker or pooling under it, the drain line is blocked and needs to be cleared or replaced.
• Kenmore ice makers typically need 24 to 48 hours to produce the first batch of ice after thawing or repair.

Locate and inspect the water line connection

The water line runs from the back of your refrigerator to the ice maker inside the freezer. On most Kenmore models, you will find the connection point at the bottom rear of the unit. Unplug the refrigerator and pull it away from the wall so you can see behind it clearly. Look for a small plastic or copper tube—this is your water supply line.

Check where the line connects to the refrigerator. If you see water pooling or dripping, the connection may be loose. Tighten the fitting by hand first, then use an adjustable wrench to turn it one quarter turn clockwise. Do not over-tighten—you only need it snug enough to stop the leak. If water is still dripping after you tighten it, the fitting itself may be cracked and will need to be replaced.

Clear a blocked or frozen fill valve

The fill valve is a small solenoid (electrically controlled valve) that opens to let water into the ice maker. When mineral deposits from your water build up inside it, the valve gets stuck and water cannot flow. You will know this is the problem if the ice maker is running but no water is entering the ice cube tray.

To clear it, first unplug the refrigerator. Locate the fill valve—on most Kenmore models it is mounted on the back wall of the freezer or on the back exterior of the unit. Disconnect the water line from the valve by turning the fitting counterclockwise. Hold a cup under the connection and turn the water supply valve (usually under your sink or in the basement) to the on position for a few seconds. If water flows out, the line is clear. If nothing comes out, the line itself is blocked and needs to be replaced.

If water flows from the line but the ice maker still does not fill, the valve itself is stuck. You can try soaking the valve in white vinegar for 30 minutes to dissolve mineral buildup, but most of the time a stuck fill valve needs to be replaced. Kenmore sells replacement valves for most models—check your refrigerator's model number (usually on a sticker inside the fridge) and order the correct part.

Check the ice maker's drain line

Every ice maker has a small drain line that carries away water that does not freeze. If this line gets blocked by ice or debris, water backs up and either leaks inside the freezer or pools under the ice maker. You will see this as water dripping from the ice maker or collecting in a puddle on the freezer floor.

Locate the drain line—it is usually a thin tube running from the bottom of the ice maker toward the back of the freezer. If you see ice buildup around it, use a hair dryer on low heat to melt the ice away. If the line looks clear but water is still pooling, the blockage is deeper in the line. Disconnect the line from the ice maker (it usually pulls straight out) and pour warm water through it slowly. If water does not flow, the line is clogged and should be replaced.

Test the ice maker after repairs

Once you have made your repair—whether thawing a line, tightening a connection, or replacing a valve—plug the refrigerator back in and wait. Do not expect ice right away. Most Kenmore ice makers take 24 to 48 hours to produce the first batch of cubes after any repair or after the first time you set up the refrigerator. During this time, the water line fills, the ice maker cycles through several times, and the first cubes form and drop.

Check the ice maker tray after 24 hours. If it is still empty, feel the water line again to make sure it has not refrozen. If the line is warm and water is flowing but no ice is forming, the ice maker itself may be faulty and will need to be replaced. If water is leaking from new places, you may have disturbed another connection during your repair—retrace your steps and check all fittings.

When to replace the ice maker assembly

If you have thawed the water line, cleared the fill valve, and checked all connections but ice still is not forming, the ice maker assembly itself has failed. This is rare, but it happens. The assembly contains the motor, the fill valve, and the heating element that releases cubes—if any of these parts break, the whole assembly usually needs to be replaced rather than repaired.

Kenmore ice maker assemblies are sold as complete units and cost between $150 and $300 depending on your model. Installation takes about an hour if you are comfortable working with basic tools. You will need to disconnect the water line, remove a few screws, and slide the new assembly into place. Your refrigerator's manual (or the Kenmore website) has a step-by-step guide for your specific model number.

Prevent future ice maker problems

Most ice maker failures come from freezing or mineral buildup, both of which you can prevent. Keep your freezer temperature between 0°F and 5°F—colder than that and the water line will freeze. If you have hard water (water with high mineral content), consider installing a water filter on the line that feeds your refrigerator. A simple inline filter costs $20 to $40 and catches minerals before they reach the fill valve.

Check the water line connection once a year, especially if you live in a cold climate. A loose fitting is easy to spot and takes 30 seconds to tighten. If you are going away for more than a week during winter, turn off the water supply to the refrigerator—this prevents the line from freezing if your house gets cold.

Frequently Asked Questions

How long does it take for a Kenmore ice maker to make ice after I turn it on?

The first batch usually takes 24 to 48 hours. The ice maker needs time to fill the water line, cycle through several times, and freeze the first cubes solid enough to drop. After that, a working ice maker produces a new batch every 90 minutes to 2 hours, depending on your model and freezer temperature.

Can I use hot water to thaw a frozen water line?

Use warm water, not hot or boiling. Boiling water can crack plastic fittings or the water line itself. Wrap the line with a heating pad on low, or pour warm tap water over it slowly and let it drip. This takes longer but is safer and less likely to damage the line.

What if my ice maker is making ice but it tastes bad or smells?

This usually means your water filter needs to be replaced or you have not run water through the line long enough after first installation. Run the ice maker for 24 to 48 hours and throw away the first few batches of ice. If the taste does not improve, replace the water filter (usually located in the fridge or under the sink) and repeat.

Is it safe to use vinegar to clean the fill valve?

Yes, white vinegar is safe and can dissolve mineral buildup. Soak the valve in vinegar for 30 minutes, then rinse it with clean water before reconnecting it. This works best if you catch the problem early—if the valve has been stuck for a long time, replacement is usually faster than trying to clean it.

Why does my ice maker work sometimes but not other times?

This usually means the water line is partially frozen or the fill valve is sticking intermittently. Raise your freezer temperature to 0°F to 5°F and check that the water line is not in a cold spot where air can freeze it. If the problem keeps happening, the fill valve is probably failing and should be replaced.
