New Icemaker is not working

I replace the ice maker on my Whirlpool refrigerator model GZ25FSRXYY2 a week ago after the old one would make ice but get stuck in the cycle. The new one has not made any ice and am looking for input. It is the correct ice maker and the wiring harness was replaced as well as part of the process.

Thanks for the advice. It appears after doing some more checking that I’m not getting power from the refrigerator harness that connects to the icemaker harness. I’ve checked the ice maker harness for continuity and it all checks good. Any suggestions on what would prevent power not getting from to the refrigerator harness?
