If continuity exists for both connections,
go to step 6.
If an open circuit is found, check the integrity of
the connections of the power cord to the harness
in the dryer; harness to the machine control board;
and, the integrity of the power cord itself.
5. If it is necessary to replace the power cord,
remove the retaining clip that secures the cord
to the back panel. See figure 4. Disconnect the
cord from the main harness and the ground wire
