IMPORTANT
Electrostatic Discharge (ESD)
Sensitive Electronics
ESD problems are present everywhere. ESD may damage or weaken the electronic
control assembly. 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 unpainted
metal in the appliance.
- OR -
Touch your finger repeatedly to a green ground connection point or unpainted metal
in the appliance.
■Before removing the part from its package, touch the anti-static bag to a green ground connection
point or unpainted metal in the appliance.
■
Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.
■When repackaging failed electronic control assembly in anti-static bag, observe above instructions.
