Electrostatic Discharge (ESD) Sensitive Electronics

ESD problems are present everywhere. ESD may damage or weaken the electronic control as- sembly. The new control assembly may appear to work well after repair is finished, but failure may occur at a later date due to ESD stress.

Use an anti-static wrist strap. Connect wrist strap to green ground connection point or un- painted metal in the appliance. - OR - Touch your finger repeatedly to a green ground connec- tion point or unpainted metal in the appliance.

Before removing the part from its package, touch the anti-static bag to a green ground connec- tion point or unpainted metal in the appliance.

Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.

When repacking failed electronic control assembly in anti-static bag, observe above instruc- tions.
