Diagnosis
This points to a power issue, not a machine fault. The connection between the power cord and the unit isn't complete.
How to Fix It
First, check the obvious. Make sure the power cord is firmly plugged into both the wall outlet and the back of the ice maker. There's a connector on the back that can work loose. Next, try a different outlet—preferably one on a different circuit. If you're using an extension cord or power strip, plug the ice maker directly into the wall. These units draw a fair bit of power on startup and need a solid connection.
If That Didn't Work
Look at the power cord itself, especially near the plug ends, for any kinks, cuts, or damage. If you see any, the cord needs replacement. Also, listen very closely near the power button when you plug it in. If you hear a faint click but no lights, the internal fuse might be blown.
Heads Up
These are not designed for outdoor use or in very damp areas. If it's been in a garage or patio, moisture could have gotten into the power supply. Let it dry out completely indoors for 48 hours before trying again.
