I think my switch is bad. What is the internal diagram of this part? When I put my Ohm meter on the white / purple and white / blue the Resistance is always 0 ohms on High / Medium / Low. Off shows no resistance. Is my selector switch bad??
Answer Keith, you're on the right track. With the white/purple and the white blue wires disconnected from the switch you should have a resistance reading of 10 ohms resistance, with the knob turned to the left(lowest temp. setting. As you turn the knob to the right(clockwise) the resistance should increase and reach a resistance of 10 K ohms, when the highest temp setting is achieved. It does sound like the switch has failed, but you didn't mention the issue with the dryer. Good Luck and Thanks
