Hello, and thank you for using this service. I'll be helping you with your problem today.
So yes, it sounds like you may just need to give the icemaker some time to cycle. The icemaker will not cycle as soon as you install it. The thermostat inside the icemaker must get below 10 degrees (like a piece of meat, it takes a while to get that cold and freeze) before it starts to cycle and work. That being said, if it doesn't make ice, probably the best thing to do is determine if the icemaker isn't cycling and calling for water, or if water isn't actually making it to the refrigerator. First, make sure the freezer
is below 10 degrees because the icemaker will not cycle if the temperature in the freezer is over 10 degrees. Next, fill up the icemaker with a cup of water and wait 24 hours to see if it cycles and dumps the ice. If it doesn't cycle, replace the icemaker because it's just bad. If it cycles but doesn't fill up with water, check the fill tube behind the icemaker and if it's frozen solid, use a hair dryer and thaw it out. You can also make sure it's not frozen by pulling the refrigerator out and disconnect the water line coming from the icemaker down at the valve. Blow through the water line to make sure it's clear. If it's not frozen, you'll need to replace the electronic water valve on the back of the refrigerator where your water supply line from your house connects to your refrigerator itself.
