The water filter may be plugged with sediment, or you may have low
water pressure. The water pressure for icemakers needs to be at least 40 psi, and up to about 120 psi for proper operation. Water filters need to be changed every six months. If you would like to test your water pressure, buy an Icemaker Water Flow Tester. This will help you to determine if the water pressure at the supply line is high enough for the icemaker to function properly.
To determine if your filter is plugged, look for water both before and after the filter. It may be hard to determine if there is water flowing through the filter. Sometimes it is necessary to pull the filter out of the feed line to see if water is flowing from the exit of the filter into the refrigerator or freezer. You can do this over a bucket to catch any dripping water. Some models have a filter bypass plug to help determine if the filter is clogged. If so, you would remove the filter and replace it with the filter bypass plug. Now test your water flow.
If your refrigerator has a water dispenser, you can hold a large cup or glass under it for 20 seconds. You should have poured about 13-14 ounces of water in during the 20 second period. If you did not receive that amount, try removing the filter and bypassing it. If you now get the 13-14 oz. of water, the filter was clogged and it’s time to replace it. If not, you have low water pressure in the line, and your icemaker may not work properly.
On occasion, the water inlet tube will freeze where it enters the icemaker. This can happen because the water is dripping slowly, or the freezer is just set too cold. A hair blow dryer can be used to thaw this, but be careful around the plastic tubing. You don’t want it to crack or deform. You may want to turn the thermostat up a little bit if this is a regular occurrence. If you have a constant, regular drip, you may want to invest in a new water fill valve.
Another reason that your icemaker may not be making ice is the bail arm along the side of the icemaker. This arm must be in the lowered position for the icemaker to operate. If the arm is stuck up, it has shut the unit off. This is a safety feature of the unit. Normally, if there’s too much ice in the bin, the arm will get stuck in the raised position and keep any more water from entering the icemaker. You must lower the arm to begin making more ice.
