Recently, the icemaker in my bottom freezer jenn-air started leaking water into the ice bin. The cubes turned into a solid block of ice. The ice then completely stopped being made. So, I have replaced the water valve, melted the solid ice that formed in the tube that fills the icemaker, and have changed the icemaker itself. But, the icemaker still has no power. The lever is in the correct position. By the way, the water dispenser has never stopped working. What should I try next? My refrigerator is a jenn-air model jcb2059ges. Thanks.
