for about 4 to 6 months the ice dispenser was making a buzzing sound for about 10-15 seconds after dispensing ice. Last week in the middle of the night it became constant and I could not stop it. I finally discovered if I remove the back cover it would not close the contact switch. I then looked for the part and found your site and the solenoid I think I need....But I can not remove the front cover, do not know how to get it off.
