Here is how to change the resistor- but also pay attention-
Did you also change the connector at the same time?
If you are changing the resistor due to overheating and melting of plastic, then you need to do the connector also, or else it will repeat fail in a very short time.
Here is a step-by-step check you can do to fix it. If you are onlygetting high speed (setting 5), then most likely you have a resistorproblem, or the wiring connector to the resistor is bad. The groundwire prong being bad is a possible cause.
