Alternatively, you can touch your finger repeatedly to a ground connection point or unpainted metal in the
appliance. Before removing a replacement part from its package, touch the anti-static bag to a ground connection
point or unpainted metal in the appliance. Handle the electronic control assembly by its edges only. When
repackaging a failed electronic control assembly in an anti-static bag, observe these same precautions.
