FOR SERVICE TECHNICIAN’S USE ONLY

IMPORTANT SAFETY NOTICE — “For Technicians only”

This service data sheet is intended for use by persons having electrical, electronic, and mechanical experience and

knowledge at a level generally considered acceptable in the appliance repair trade. Any attempt to repair a major

appliance may result in personal injury and property damage. The manufacturer or seller cannot be responsible, nor

assume any liability for injury or damage of any kind arising from the use of this data sheet.

IMPORTANT: Electrostatic Discharge (ESD) Sensitive Electronics

ESD problems are present everywhere. Most people begin to feel an ESD discharge at approximately 3000 V. It takes as

little as 10 V 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.

ɃUse an anti-static wrist strap. Connect wrist strap to green earth 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.

ɃBefore removing the part from its package, touch the anti-static bag to a green ground connection point or unpainted

metal in the appliance.

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

ɃWhen 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:

ɃVerify the controls are in the off position so that the

appliance does not start when energized.

ɃAllow enough space to perform the voltage

measurements without obstructions.

ɃKeep other people a safe distance away from the

appliance to prevent potential injury.

ɃAlways use the proper testing equipment.

ɃAfter voltage measurements, always disconnect power

before servicing.

DANGER

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.

Your safety and the safety of others are very important.

We have provided many important safety messages in this manual and on your appliance. Always read and obey all safety

messages.

This is the safety alert symbol.

This symbol alerts you to potential hazards that can kill or hurt you and others.

All safety messages will follow the safety alert symbol and either the word “DANGER” or “WARNING.”

These words mean:

IMPORTANT SAFETY INSTRUCTIONS

WARNING: To reduce the risk of fire, electric shock, or injury to persons when using your appliance, follow basic precautions, including the following:

ɃRead all instructions before using the appliance.

ɃDo not dry articles that have been previously cleaned in, washed in,

soaked in, or spotted with gasoline, dry-cleaning solvents, or other

flammable or explosive substances, as they give off vapors that could

ignite or explode.

ɃDo not allow children to play on or in the appliance. Close supervision

of children is necessary when the appliance is used near children.

ɃBefore the appliance is removed from service or discarded, remove

the door to the drying compartment.

ɃDo not reach into the appliance if the drum is moving.

ɃDo not install or store this appliance where it will be exposed to the

weather.

ɃDo not tamper with controls.

ɃDo not repair or replace any part of the appliance or attempt any

servicing unless specifically recommended in the user maintenance

instructions or in published user-repair instructions that you

understand and have the skills to carryout.

ɃDo not use fabric softeners or products to eliminate static unless

recommended by the manufacturer of the fabric softener or product.

ɃDo not use heat to dry articles containing foam rubber or similarly

textured rubber-like materials.

ɃClean lint screen before or after each load.

ɃKeep area around the exhaust opening and adjacent surrounding areas

free from the accumulation of lint, dust, and dirt.

ɃThe interior of the appliance and exhaust duct should be cleaned

periodically by qualified service personnel.

ɃDo not place items exposed to cooking oils in your dryer. Items

contaminated with cooking oils may contribute to a chemical reaction

that could cause a load to catch fire. To reduce the risk of fire due

to contaminated loads, the final part of a tumble dryer cycle occurs

without heat (cool down period). Avoid stopping a tumble dryer before

the end of the drying cycle unless all items are quickly removed and

spread out so that the heat is dissipated.

ɃDo not use replacement parts that have not been recommended by the

manufacturer (e.g. parts made at home using a 3D printer).

ɃSee the Installation Instructions for grounding requirements and

installation.
