The ice/water lights work, but all of a sudden they are not dispensing anything. There is ice in the bin, which I emptied & it started over producing ice & I took out the water filter to see if that was the issue. Nothing's worked so far. (It quit after the kids went back and forth from ice to water to ice very quickly, so we blamed them at first. But if there was a child lock function (like with car windows & car locks), it should have re-set by now, right?) Any ideas?
