It sounds like your original problem was either the water fill time was too low or that the thermistor inside the ice maker was not working properly. It is possible that the motor in the ice maker was faulty and when it was jammed it caused it to burn out.

There is no fuse that you need to reset when replacing the ice maker. You should only have to plug it in and it should start working by itself. I suggest that you check the ice maker by manually moving the ejector arm forward slightly. If the ice maker is working properly, the ice maker should then proceed to perform a full cycle. When it gets to the end make sure to check if the water valve is activated and dispenses water into the ice tray.
