IMPORTANT SAFETY NOTICE

The information in this service guide is intended for use by individuals possessing adequate backgrounds of electrical, electronic, and mechanical experience. Any attempt to repair a major appliance may result in personal injury and property damage. The manufacturer or seller cannot be responsible for the interpretation of this information, nor can it assume any liability in connection with its use.

!

WARNING !

To avoid personal injury, disconnect power before servicing this product. If electrical power is required for diagnosis or test purposes, disconnect the power immediately after performing the necessary checks.

RECONNECT ALL GROUNDING DEVICES

If grounding wires, screws, straps, clips, nuts, or washers used to complete a path to ground are removed for service, they must be returned to their original position and properly fastened.

WHAT TO DO IF YOU SMELL GAS:

■ Do not try to light a match, or cigarette, or turn on any gas or electrical appliance.

■ Do not touch any electrical switches. Do not use any phone in your building.

■ Clear the room, building or area of all occupants.

■ Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions carefully.

■ If you cannot reach your gas supplier, call the fire department.

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.
