Of all the times you need your ice maker, summer can be the most demanding. But what if you find your refrigerator ice maker not making ice when the summer sun is at its hottest? We’ll review the 5 most likely causes for this common problem from a high freezer temperature to low water pressure.
Troubleshooting a Refrigerator Ice Maker Not Making Ice
Sometimes finding the source of the problem can be just as frustrating as the problem itself. Our list of causes for a refrigerator ice maker not making ice cuts to the chase with the 5 most likely reasons why.
#1. Freezer Temperature is too High
Ice maker troubleshooting should start with the freezer temperature. If the freezer’s temperature is too high, the ice maker won’t be able to produce ice. Check to make sure the freezer’s temperature is set between 0-5°F for optimal ice production.
If the freezer is above 5°F and the refrigerator is warm as well the refrigerator’s condenser coils could need cleaning. When the coils are coated in dust and dirt, the refrigerator has to work harder to maintain cool temperatures.
#2. Water Inlet Valve is Frozen or Clogged
The freezer’s water inlet valve is electronically controlled, opening and closing to supply the ice maker with water as needed. Over time, the valve can become clogged with frozen water, cutting off the supply to the ice maker. When this happens you may notice your ice maker slow making ice or the ice is smaller or misshapen.
In addition, the water inlet valve has a screen that can become clogged with sediment and particles, also restricting the ice maker’s water supply. A frozen inlet valve can be thawed with hot water while a clogged screen can be removed and rinsed.
#3. Water Supply Pressure is Low
The water inlet valve also requires a certain amount of water pressure to allow water to flow to the ice maker. If the valve’s pressure is less than 20 psi, it may not open and close properly, resulting in the ice maker not making ice.
To test the water pressure, shut off your water supply, and disconnect the water valve’s supply line. Place the line over a bucket and turn the water supply back on. If there is a weak flow of water from the supply line, then your home’s water pressure is too low.
#4. Ice Maker Control Arm is Off
Another reason for the ice maker not working could be the control arm’s position. The ice maker is turned on when the control arm is in a downward position. However, shifting items in the freezer can push the arm up, turning the ice maker off.
To make sure your ice maker is on, confirm that the control arm is in the downward position.
#5. Ice Maker Assembly is Defective
If these interventions still leave you with a refrigerator ice maker not making ice then it’s possible the ice maker assembly is defective. If there is one defective component then it’s often necessary to replace the entire assembly, as most parts aren’t sold separately. We recommend professional service for this job.
