Our dryer, an LEC6848A Whirlpool, recently decided it didn't want to
start. Turns out though, we discovered if we very carefully rotate
the cycle knob, we can in fact find spots on the dial where it will
start up, so we have been doing that to run it. Does this mean
there's a pot wiper that's gone through the resistance layer in most
of the travel? So we need to replace the 'control knob assembly'?
