My icemaker makes noise when I try to dispense crushed or cubed ice, but the auger does not turn. I looked closely at the blades which crush the ice and noticed one of them is interlocked with an adjacent (stationary, I guess) blade, keeping anything from moving. Is this worth trying to fix? There was a top panel covering the blade chamber that locks into place, but I couldn't quite get the thing off. I've attached photos of the blades and the panel that I had trouble removing. Thanks for any advice concerning removing the panel or dislodging the blade.
