the icemaker module is making a funny noise and seems to be stuck. Yeterday would not dump out the ice manually removed and now won't make anymore ice. Ice molds are not filled with water. Pulled cover off motor module and wheel not turning but making strange noise. Is it easy to replace this part? I found it online for about $45. If I pull off the existing module am I going to be assulted with an overwhelming amount of wires and do I need any electrical equipment to install a new one? I know the power needs to be disconnect before removing existing motor module.
