Professional service for icemaker lines should only be called in after ample troubleshooting.
It is hard to immediately assume that when there is a problem with your icemaker that the line is the issue. It is also possible that leakage can occur at various points of contacts. Another possible cause is that the unit may not be perfectly level, which contributes to leakage.
Before you attempt to level the freezer, it is important to unplug the unit as safety precaution. Use a spirit level on top of the freezer as a guide to its level. Adjust the leveling feet accordingly to perfectly align the freezer from left to right. Do this from all sides to verify that everything is leveled.
The icemaker unit must also be leveled by loosening the mounting screws. Reposition the unit if needed and align the icemaker to ensure a perfect level. Tighten the mounting screws once everything has been leveled to prevent the icemaker from shifting or moving.
The most common problem to troubleshoot with the water supply line is to visually inspect for damages or breaks. If you are not familiar with the water supply line, this is the tube that is found at the back of the freezer. Its material is relatively strong which makes it fairly prone to damage. Check the pipe for kinks and pinches as well.
The fill cup is used to receive the water as it enters the freezer. It acts as a funnel that is responsible for directing the water into the molds to form ice cubes. When it is not aligned properly you may experience problems like leaks. Ice that is forming on the fill cup is an indication of a broken or faulty valve.
Corrosion and damage are the things to be on the lookout for with the inlet switch. You must remove it to be able to visually inspect it. If you see any corrosion on its terminals, you must replace it. A multimeter is needed to check if the inlet switch is properly working. Check if it connects and reduces resistance by pressing the switch a couple of times.
For safety purposes, it is important to disconnect any power to the freezer before you begin troubleshooting the inlet valve. This can be found at the bottom of your freezer. Cut off the water supply from the source and disconnect the supply line. Have a bucket ready to catch any water that may be pouring from inside the inlet valve.
When you disconnect wires, make sure that you properly label them to make it easier to reconnect them. The inlet supply tubes must also be removed. Check the resistance of the coil using a multimeter. You should be aware that the inlet valve can fail electronically and mechanically so you must check its mechanical function as well.
