Does your ice maker need repair? If your ice maker doesn’t make ice or doesn’t work at all, check out these do-it-yourself ice maker repairs before calling a pro.
Troubleshooting and repairing an ice maker are jobs that do-it-yourselfers can handle with a little bit of guidance.
An ice maker receives water through a small, 1/4-inch water supply line that runs from the refrigerator to a water pipe, where it is connected by a tap valve. The water supply line enters a valve in the refrigerator that is controlled by an electric solenoid that sends water through a fill tube into a mechanized ice maker assembly. There, the water freezes and is dumped into an ice bin. When the bin is full, the ice lifts a bail wire that turns off the unit.
The most common problems that occur with an ice maker are a failure to make ice, a failure to stop making ice, and the unit freezing up altogether. We offer instructions on how to troubleshoot your ice maker and how to make ice maker repairs if one of these problems occurs, beginning with the most common problem—the ice maker failing to make ice.
If the water’s route is blocked or the solenoid doesn’t work—or if the bail wire is lifted—the ice maker won’t make ice. (Also note that your home’s water pressure may not be strong enough to serve an ice maker.)
Here are a few steps you can take to get your ice maker working (first make sure the bail wire above the ice tray is in the down position):
1Check the water supply line. If the ice maker doesn’t make ice but you can see the arm swing into motion and you hear a buzz for about 10 seconds, the water valve is asking for water that isn’t arriving. This means the valve and the solenoid are probably okay, but the water supply is not. Be sure the water supply line isn’t kinked behind or beneath the refrigerator (1/4-inch copper tubing is much better than plastic fill line).
2See if the fill tube is frozen. Check to see if something has caused ice to back up around the mechanism—this can cause the fill tube to freeze. When ice cubes are small and seem to be getting smaller, it generally indicates a frozen fill tube.
3Check the water line that enters the back of the freezer for a blockage. Find the water shut-off valve behind the refrigerator or under the sink, turn it off, unscrew the copper line from the back of the refrigerator, put the copper line in a bucket, turn on the valve, and see if water pours out.
4Check the tap valve. A bad tap valve—the little device that connects the ice maker’s water supply tube to the water pipe—may cause the problem where the ice maker’s supply tube connects to the water pipe. If necessary, replace the inlet valve and the tap valve. For the tap valve, use the type that requires you to drill a 1/4-inch hole (as opposed to the “self-piercing” type). You can buy an ice maker connection kit and do this yourself, or call a repair person or plumber to install an inline water filter when replacing the valve.
5Check the solenoid. The water line attaches to a solenoid at the back of the refrigerator and then travels to the ice maker. The solenoid may be defective or may not be receiving power. You can try removing the sediment screen inside the solenoid and flushing it with water to clean it, and at the same time you can inspect any seals or diaphragms to ensure that they are sound. Unplug the refrigerator first.
If your ice maker keeps making ice, even when it is full:
1Lift the bail wire to shut off the ice maker, and remove the ice bin. Then, using a screwdriver if necessary, remove the ice maker, clean it thoroughly, and then reinstall it.
2If the problem persists, consider having an appliance repair person remove and replace the entire ice maker and valve. With this type of problem, you can have it repaired, but it’s often wiser and less expensive in the long run to replace the unit entirely.
This ice maker repair is even easier. If your ice maker has frozen up, take the following steps to thaw it out:
1Unplug the refrigerator. Remove the ice bin from the refrigerator and remove any loose ice from the ice maker.
2Find the fill tube. This is awhite rubber-like hose that delivers water to the ice maker. Pull down the small metal clip off the housing that holds the fill tube (though not all ice makers have this clip).
3Warm the hose and surrounding mechanism. To do this, you can train a hair dryer on the ice maker to melt any ice blocking the mechanism. But be very careful (sop up any dripping water with a rag) as electricity and water can present a serious risk of electrical shock. Also, be careful not to melt the plastic parts.
4If you don’t want to use a hair dryer, you can soak the supply tubing with hot water, using a turkey baster and catching the overflow in the empty ice maker bin. In some cases, it may be easier to remove the ice maker than to thaw out the fill tube.
