The resistors are there... but are they still connected together? 
Excuse me for using the wrong terminology (and possibly not remembering 
things right... it's been a few years since I had mine apart), but there 
should be 3 inputs (one for each speed) and 1 output.  If you measure 
the resistance between the input and each output the resistance should 
change in steps.  If the resistance is off-scale then you found the break.

I believe there is a small bit of wire that bridges two of the coiled 
resistors together.   On my old speed control, this wire had melted 
disabling all but the High speed.   Repairing this bridge with a piece 
of wire and some solder fixed the speed controler.
