This annoying problem can have a variety of causes. Check these four things first:
- Make sure the water supply is greater than 20 psi. If too low, the water valve won’t seat properly and it’ll “weep.” Common causes of low pressure are gunked-up saddle tap valves, kinked water supply line, and using a reverse osmosis filter to supply water to the icemaker.
- Check between the valve diaphram and valve seat for sediment. If found, do not attempt to repair, buy a new valve.
- Check to see if the black, flexible portion of the fill tube is wrinkled, twisted, or kinked which can cause ice dams that block the fill tube.
- Find out if the water has been shut off while the icemaker has kept on cycling. This, too, can cause the fill tube to freeze up.
If all the above checks out and you’re still getting fill tube freeze-ups, there’s still one thing left to try.
It turns out that the manufacturer’s have been scratching their heads about this, too, and have concluded that the new fill tube air slit design helps prevent this problem. Buy your replacement fill tubes for your fridge through the links below:
Well al-l-lrighty then.
