All Models

Check continuity between switch terminals as shown in Fig 1 through Fig 8. An ohmmeter must be used to test both systems. To detect marginal operation of the switch, move control knob while each reading is being taken. If switch does not indicate continuity as shown or poor continuity exists during movement, replace switch.
