• If resistance is not in¿ nite, replace the Selector
Board.
• If resistance is in¿ nite, slowly rotate the
selector knob in either direction. As switch
passes from one detent to the next, resistance
should read approximately 0 Ÿ.
• If resistance is not approximately 0 Ÿ, replace
Selector Board.
• If resistance is approximately 0 Ÿ, repeat the
steps above for pins 2 and 3.
• If resistance readings are correct, check
resistance between pins 4 and 5. Resistance
should be in¿ nite. If not, replace Selector
Board.
• If resistance is correct, press the selector knob
in. While knob is pressed in, resistance should
be approximately 0 Ÿ.
