Important information to know about glass shelves
and covers:
Do not clean glass shelves or covers with warm water when
they are cold. Shelves and covers may break if exposed to
sudden temperature changes or impact, such as bumping.
Tempered glass is designed to shatter into many small,
pebble-size pieces. This is normal. Glass shelves and covers
are heavy. Use both hands when removing them to avoid
dropping.

Safety
DANGER
Electrical Shock Hazard
Only authorized technicians should perform
diagnostic voltage measurements.
After performing voltage measurements,
disconnect power before servicing.
Failure to follow these instructions can result in
death or electrical shock.
WARNING
Electrical Shock Hazard
Disconnect power before servicing.
Failure to do so can result in death or
electrical shock.
Replace all parts and panels before operating.
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.
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 antistatic 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 antistatic 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 antistatic bag, observe above instructions.
