The problem started about a week ago when the lights on the ice maker just turned off and it would stop functioning. When this happens I typically hear a *thump* sound every other second. If you attempt to dispense ice or water when the display is dark, the thump continues but you also hear a beep and the lights flash at the same interval as the sounds. Every now and then, there is a loud click that used to occur right when dispensing ice (when it was working properly). Then suddenly, everything is back to normal and it works fine.
