Kenmore Ice Maker Not Working But Water Dispenser Is
Your Kenmore ice maker not working but water dispenser is tells you one thing right away. The water supply line to the fridge is fine. That narrows the problem dramatically.
As of 2026, the most common cause of this specific symptom is a frozen fill tube. The ice maker's control module needs a signal from the thermostat before it calls for a fill cycle. When the tube freezes, water can't reach the mold.
The ice maker stops producing.

Quick Answer
If your Kenmore ice maker isn't working but the water dispenser is, the fix is inside the freezer. Check the power switch and sensor arm first. Then look for a frozen fill tube.
Thaw it with a hair dryer on low heat. Test the thermostat if the ice maker still won't cycle.
The Simple Checks First: Power Switch, Sensor Arm, and Freezer Temperature
Start with the easy stuff. The ice maker has a power switch or a sensor arm. It acts as a shutoff.
If the arm is in the up position, the ice maker thinks the bin is full. It will not run a cycle.
Look for the arm on the side of the ice maker. Push it down. If it clicks back up, the arm is working.
If it stays down, the ice maker should start making ice within a few minutes.
Next, check the freezer temperature. The ice maker needs 0°F to 5°F to work properly. If the freezer is above 10°F, the ice maker will not cycle.
Use a thermometer to confirm the temperature. If it is too warm, adjust the freezer setting and wait 24 hours.
If both the arm and the temperature check out, move to the fill tube.
The Frozen Fill Tube: The Most Common Cause When the Dispenser Still Works
The fill tube is a small plastic channel. It runs from the back of the freezer wall to the ice mold. It is the most common failure point when the water dispenser works but the ice maker does not.

The fill tube sits inside the freezer. Moisture in the air can condense inside the tube. That moisture freezes and blocks the water path.
The dispenser still works because it uses a separate water line. The ice maker can't get water because the tube is blocked.
Here is how to check and fix it.
| Step | Action | What to Look For |
|---|---|---|
| 1 | Open the freezer door | Look at the small plastic tube that drops water into the ice mold |
| 2 | Shine a light inside the tube | Frost or ice inside the tube means a blockage |
| 3 | Thaw the tube with a hair dryer | Use low heat. Hold it 6 inches away. Do not melt the plastic |
| 4 | Run the diagnostic test | Press the test button on the ice maker 3 times in 5 seconds |
If the tube was frozen, the ice maker should start cycling within 10 to 15 minutes after thawing. If it does not, the problem is elsewhere.
Testing the Ice Maker Thermostat, Heater, and Control Module
If the fill tube is clear and the ice maker still won't cycle, the issue is likely in the ice maker module itself. The thermostat, heater, and control module work together to run the cycle. One of them has failed.

The thermostat is a small disc-shaped component on the side of the ice maker. It tells the control module when the mold is cold enough to start a cycle. You can test it with a multimeter.
| Component | Resistance (Ohms) | What It Means |
|---|---|---|
| Thermostat at room temp | 2,000 to 5,000 | Normal |
| Thermostat at freezer temp | 0 (closed circuit) | Normal |
| Heater | 100 to 200 | Normal |
| Heater | Infinite (open circuit) | Failed |
To test the thermostat, disconnect the ice maker from power. Remove the two wires from the thermostat. Set your multimeter to ohms.
Touch the probes to the two terminals. If you get infinite resistance, the thermostat is bad.
The heater is located under the ice mold. It helps release the ice cubes. If the heater fails, the ice maker will freeze cubes but won't drop them.
Test it the same way. If the resistance reads infinite, the heater is dead.
If both the thermostat and heater test fine, the control module is likely the culprit. The control module is the circuit board inside the ice maker. It is not user-serviceable.
You will need to replace the entire ice maker assembly.
When the Water Inlet Valve Is the Problem (It's Rare, But Possible)
The water inlet valve is the solenoid that opens to let water into the ice maker. It has two separate circuits. One circuit feeds the water dispenser.
The other feeds the ice maker.
If the dispenser works, the valve is getting power. But the ice maker side of the valve could still be bad. This is rare.
It happens when one coil inside the valve fails while the other coil stays good.
You can test the valve with a multimeter. Disconnect the power. Find the two wires that go to the ice maker side of the valve.
Touch the probes to the terminals. The resistance should be between 500 and 1,000 ohms. If it reads infinite, the valve needs to be replaced.
If the valve tests fine, the problem is almost certainly in the ice maker module itself. At that point, the most practical fix is to replace the entire ice maker assembly. It costs between $40 and $80 for a new one.
It takes about 15 minutes to install.
Common Mistakes That Waste Time and Money
The biggest mistake is replacing the water inlet valve first. Many people assume the valve is bad because the ice maker isn't filling. But the dispenser works.
That means the valve is getting power and opening.
The odds of one coil failing while the other stays good are low. Another common error is ignoring the sensor arm. It is easy to bump the arm up when you reach for something in the freezer.
If the arm is up, the ice maker thinks the bin is full. It will not cycle. Check the arm before you buy any parts.
A third mistake is testing the thermostat or heater while the ice maker is still connected to power. You can short the circuit or damage the control module. Always unplug the refrigerator before you test anything.
Per UL safety standards, working on live components inside a freezer is a shock hazard.
Some people also try to thaw the fill tube with a metal tool. Don't do this. The plastic is fragile.
A screwdriver or ice pick can crack the tube. If you crack it, the tube will leak water into the freezer. Use a hair dryer on low heat.
It takes 10 minutes and works.
Frequently Asked Questions
Why does my Kenmore ice maker stop working after a power outage?
The ice maker may need to be reset. Press the test button three times within five seconds. The ice maker should run a diagnostic cycle.
If it does not, unplug the refrigerator for 30 seconds and plug it back in.
How long does it take for a Kenmore ice maker to make ice after a fill tube thaw?
It takes about 10 to 15 minutes for the ice maker to start a new cycle. A full cycle takes 90 to 120 minutes. The first batch of ice may be small or cloudy.
This is normal.
Can a bad water filter cause the ice maker to stop but not the dispenser?
Yes, but it is rare. The filter can clog and reduce water pressure. The dispenser may still work because it has a stronger valve.
If the filter is more than six months old, replace it. OEM spec recommends a new filter every six months.
How do I know if my Kenmore ice maker control module is bad?
If the thermostat and heater both test fine, the control module is the likely culprit. The ice maker will not cycle at all. There is no test for the module itself.
The only fix is a new ice maker assembly.
Should I call a repair technician or replace the ice maker myself?
If you have a multimeter and basic tools, you can test and replace the ice maker yourself. A new assembly costs $40 to $80. A service call typically costs $150 to $250.
If you are not comfortable with electrical testing, call a technician.
