15 CHECKING THE EFFICIENCY OF THE COMPONENTS
In order to facilitate the control procedure for the components to be tested, a TEST PROCEDURE has been
created which indicates the point to which the probes of the tester should be applied and the correct
theoretical value for each component tested.
Remove the door and detach all the connectors from the main board.
Connect the probes of the tester to the appropriate points on the connector. Compare the ohmic reading
with the theoretical value.
Care should be taken relative to the position of connector "B1" - "B2": if this connector is
replaced in the incorrect position (back-to-front), the appliance will not function
since the power
supply will be disconnected.
