Troubleshooting a Refrigerator Ice Maker Not Dispensing
If your refrigerator is not dispensing ice, there are two possible causes for the problem. These causes are:
- The ice maker is not working
- The ice maker is not dispensing ice
If you suspect that the ice maker is not working properly, you must take the following steps.
Check the Condition of the Water Supply Line
If the ice maker of your home appliance is not working and you hear a buzzing sound for about 15 seconds, it means that the water valve is asking for more water. To solve this problem, you must try to identify the reasons for disruption in the water supply. Make sure the tube that supplies water to the ice maker is not kinked. This tube is usually located beneath or behind the refrigerator.
Frozen Fill Tube
If the ice cubes are getting smaller by the day, it indicates that the fill tube is frozen. There are several parts that can be responsible for this problem. Therefore, it is best to get help from a professional refrigerator repairman to solve this issue safely.
Check the Ice Mold
If there is no change in the size of the ice cube, you must check the condition of the electric connections that control the working of the ice mold and supply fill valve. Checking these electric connections involves live-voltage tests, which must be performed by professionals.
Inspect the Water Supply Line for Blocks
The tube that supplies water to the freezer may be blocked. To check the condition of the water supply line, you must locate the shut-off valve and turn it off. Dismantle the water supply tube and put one end of the tube in a bucket. Turn on the valve and check if the water pours out of the tube. If water does not pour out, you may have to change the tube.
Check the Condition of the Tap Valve
The tap valve is a small device that connects the water supply tube of the ice maker to the water supply pipe of your house. If the tap valve is damaged, it may disrupt the water supply to the ice maker. You may have to replace the valve when it is broken or damaged. When buying a new valve, make sure you get the exact size, as an irregular size will not fit the water supply tubes properly.
Check the Solenoid
The house water supply line attaches to the solenoid, which is usually located at the bottom or back of the household appliance. If the solenoid does not receive power or is defective, it may disrupt the water supply to the ice maker. If you suspect the solenoid is the problem, disconnect the power supply to the machine. Remove the sediment screen from the solenoid and clean it with water. Also, check the condition of diaphragms and seals that are attached to the solenoid. If any part is damaged, you must replace it immediately.
Ice Bucket Auger Issues
The auger is located in the machine’s ice bin and it is responsible for pushing out ice when the dispenser is activated. This part is driven by a motor that is mounted behind the ice bin. If the ice bucket auger is not working, you must first verify the operation of the motor. The gearbox of the motor will make some noise when it is operating. You can easily hear this sound when the freezer door is closed.
If the motor is not working, you can check the continuity using a multi-meter. Before performing this test, disconnect the power supply to the machine. If there is no problem with the motor, you must check whether the motor is receiving a power supply. If there is no power supply, you must check the condition of the switch and the actuator.
Ice Dispenser Actuator and Micro Switch
The actuator is responsible for activating the micro switch of the dispenser. The actuator is usually a plastic lever that is covered by a soft pad. You will hear a click sound when the actuator contacts the switch. If the motor or the dispenser is not receiving power, you must check the condition of the micro switch and the actuator. If you suspect that the actuator is responsible for the problem, you should check the actuator assembly and replace any defective parts.
The micro switch is activated when it receives a physical signal from the actuator. The switch is located behind the lever or pad and it dispenses ice when it is pressed. To check its condition, disconnect the power supply and remove the control panel cover to test for continuity using a multi-meter.
If you are still not able to locate the problem, it is best to get help from an expert. Professional technicians can assist with everything from ice maker repairs to general dishwasher and dryer service.
If your unit is still failing to produce ice, you may need help troubleshooting compressor issues or water line faults. For more appliance repair information, visit our main page.
