Water was over flowing and making blocks of ice

It looked easy on the video so I ordered the icemaker. It was easy to remove, except for the electric connection. I then realized that the water outlet opening did not fit. Mine comes from the back. I took a chance and replaced the old fitting for the new so the water tube would fit. It took me a while to figure how to do this. The icemaker did not function until the next day, but has been working fine since. My husband is happy and I am sure I saved at least $200.00 or more.
