IMPORTANT: Electrostatic Discharge (ESD) Sensitive Electronics
ESD problems are present everywhere. Most people begin to feel an ESD discharge at
approximately 3000V. It takes as little as 10V to destroy, damage, or weaken the main control
assembly. The new main control assembly may appear to work well after repair is finished,
but a malfunction 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 main control assembly in anti-static bag, observe above instructions.
Voltage Measurement Safety Information
When performing live voltage measurements, you must do the following:
Verify the controls are in the off position so that the appliance does not start when energized.
Allow enough space to perform the voltage measurements without obstructions.
Keep other people a safe distance away from the appliance to prevent potential injury.
Always use the proper testing equipment.
After voltage measurements, always disconnect power before servicing.
