Bosch Evolution 300 Series - Gas Range Component Testing

3:8
If
a component part that is controlled by the control module fails to
operate the cause could be due to a defect in the control module,
faulty wiring harness connections , or the nonfunctioning component.
Component parts such as elements, fan motors, lock motors, etc. can
be tested with a simple continuity check using an ohmmeter. Verify
the continuity of the component and the wiring circuit between the
component to the control module first.

If the component and wiring connections are good test the output
voltage from the control module to the component part.
NOTE: Resistance measurments are approximate. Variations due to
temperature changes and other factors are normal.
