My old icemaker lost some of the nonstick surface and the ice didn't want to come out

I unhooked the wire harness from the ref. and took out three screws and pulled the old unit out. I than changed a few parts from the old icemaker to the new and reattached the new ice maker to the ref. and plugged the wire back in. everything is working fine. No problems. Also I was very happy with the ordering process. Thank you!!
