We fixed it by calling Appliance Parts Pros after Whirlpool had no comment as to the cause! Please call a repairman for $150 - $200. Considering it cost approximately $22 including shipping for the part no way. APP was a great help, non- judgmental as to our expertise and our part came very quickly. An easy fix and I'm a happy camper with good hot temp to sterilize my dishes. Once disconnected from the power source even a child could do it. All it was, was a fuse. Plug and play!
Now I have an ice maker to repair and will definitely get the parts from Appliance Parts Pros.
