Product review (5 stars): Exact replacement at great price
As I understand it from reading on the internet about icemakers in modern refrigerators, the icemakers only last about 5-6 years.  I had a problem with my LG French door refrig after about a year.  At that time, LG replaced at no charge.  About 5 years later, the icemaker stopped working again.  I tried pressing and holding the ice sizing button, but that didn't help.  I also took the icemaker apart and found ice in the gearing - but that didn't fix the problem.  So, replacing the icemaker was the next step.

Replacing the icemaker is relatively easy....2 mounting screws that are easily accessible, 1 electrical connection, and a screw for the ground wire.  Connecting the electrical connection and ground wire screw to the new icemaker is a little awkward, but doable.  After installation, I had to press and hold the ice sizing button to get the new icemaker started.

I'm thinking of getting a second icemaker for when this one goes bad in about 5 years.
