At first glance, a non-working ice maker in a fridge may seem like a simple issue—just replace it with a new one, and everything will be fine. However, in reality, there are many possible reasons why an ice maker might not be functioning. Let’s go over some common causes and provide recommendations for diagnosing and fixing the issue when possible. Read more about our refrigerator repair:
Reasons Why the Refrigerator Ice Maker Not Making Ice
- The Ice Maker Is Turned Off
- No Water Supply to the Ice Maker
- Ice Maker Heating Element Is Burned Out
- Clogged Water Filter
- High Freezer Temperature
- Ice Maker Temperature Sensor Failure
- Other Possible Causes
The Ice Maker Is Turned Off – №1
One of the most common reasons for an ice maker not working is that the user has simply not turned it on. Either the ice maker switch on the fridge’s control panel is off, or the ice maker arm is in the up position, which means it is turned off.
Solution
Visually inspect the control panel or the ice maker itself and ensure that it is switched on.
No Water Supply to the Ice Maker – №2
If the ice maker is not getting water, it won’t be able to produce ice.
Solution
Move the refrigerator slightly and check if the water supply valve on the wall is open. Additionally, make sure that water is actually flowing from the valve by briefly testing it. If you’re unsure how to inspect or fix the problem, it’s best to call a professional technician for a thorough diagnosis and repair.
Diagnosis and repair cost: from $150
Ice Maker Heating Element Is Burned Out – №3
The ice maker has a small heating element that helps release the ice cubes. If this component fails, the ice may get stuck in the mold, preventing new ice from forming.
Diagnosis
Check manually or visually if there is frozen ice stuck in the ice maker’s tray. If you find ice that isn’t being ejected, you may need to replace the entire ice maker.
Replacement cost: from $300
Clogged Water Filter – №4
The water filter plays a crucial role in ensuring clean water flows to your refrigerator’s ice maker. Over time, the filter can become clogged with impurities, mineral deposits, or debris, restricting or completely blocking water flow. When this happens, the ice maker may produce smaller ice cubes, take longer to make ice, or stop working altogether. A clogged filter can also affect the taste and clarity of the ice.
Solution
Check when you last replaced your fridge’s water filter. Remember, the filter should be replaced every six months for optimal performance.
Maintenance cost: from $200
High Freezer Temperature – №5
If the freezer temperature is above 5°F (-15°C), the ice maker may stop working completely or produce very little ice, usually at night when the freezer door remains closed for a long time.
Solution
Use a thermometer to check the freezer temperature. If it’s 5°F or higher, you should call a technician, as identifying and fixing the root cause of high freezer temperatures can be difficult without professional tools.
Diagnosis and repair cost: from $300
Ice Maker Temperature Sensor Failure – №6
The ice maker relies on a temperature sensor to determine when to dispense ice or fill the mold with water. If the sensor is defective, the ice maker may receive incorrect signals.
Solution
Unfortunately, diagnosing a faulty temperature sensor requires specialized tools. If you suspect this issue, it’s best to contact a professional technician.
Diagnosis and repair cost: from $300
Other Possible Causes – №7
Some ice maker issues are more complex and require a trained technician to diagnose and repair. These include:
- A faulty main control board or ice maker control board
- Broken wires inside the freezer door, especially if the ice maker is built into the door
- A frozen water supply tube, preventing water from reaching the ice maker • A malfunctioning water inlet valve that fails to open properly
All of these issues require specialized knowledge and experience. If you are unable to determine the cause of the problem, it’s best to call an experienced appliance repair professional.

My ice maker was working fine last night, but today—nothing. The freezer is still cold, so I don’t think it’s completely broken. Could this be a clogged water line? I don’t want to mess with it too much and make it worse. Any advice before I call someone?
Hi Jessica!
First, check if there is still ice in the ice maker or if it is empty. If there is ice left, the issue is most likely with the ice maker itself. If there is no ice, check when you last replaced the water filter—it should be changed every six months. If necessary, replace it.
A good way to check if the filter is working properly is to test the water dispenser. If water flows from the dispenser, then the filter is fine, and the issue lies elsewhere. In this case, you should call a technician to diagnose and fix the problem.
Serhii, thank you! I reached out to you and was very pleased with the results. I wanted to leave a review but couldn’t find where, so I’m writing here. Guys, my ice maker is working again! We practically diagnosed the issue over the phone, and in the end, it just needed a filter replacement and some general fridge maintenance. I’m really happy with the service—quick, efficient, and reasonably priced. I highly recommend Serhii! Even over the phone, I could tell I was dealing with someone experienced and knowledgeable. Thank you!
Hi Jessica, thank you for the update — I really appreciate your kind words!
