Before you go tearing the freezer apart...
I have the problem of the ice maker not producing ice a couple of times a year.
Your ice maker has some sort of device to stop ice production when the bin is full. On mine it's a wire frame that moves up and down with the level of ice in the bin. When the wire is at the top, production stops. When it's below that point, production continues.
The water in the ice maker goes into a small tray that has a thermocoupler in it. When the water in the tray reaches freezing temperature, the cubes are released into the bin.
When the wire frame is in a lowered position, and the thermocoupler doesn't detect ice, a signal is sent to the water valve to open.
Move the wire frame or whatever device you have that controls the amount of ice in the bin to the lowest position, so that ice production is "on." Fill the small tray with about 1/4th cup of water, and wait fifteen to thirty minutes. If you have new ice cubes, then your problem is with the water supply valve.
The water supply valve can stop functioning if a small bit of rust from the water pipes gets in it. I found that repeating the above steps eventually gets the water valve to open, the speck goes somewhere else, and everything is fine.
