Electric, Kitchen Aid stove/oven does not have any power. Turned a burner knob, heard a pop, saw a spark, and whole unit went dead. Checked hose panel fuse and it was not blown. After taking knob off we discovered that the post to hold the knob was not as tall as it should be, we got pliers to pull post back out, and then put knob back on. The collar holding the post up needed to be tightened. Still have no power to the stove, no clock or display.
