IMPORTANT SAFETY NOTICE
The information in this service guide is intended for use by individuals possessing skill and experience in electrical, electronic, and mechanical appliance repair. 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.
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.

Stacking Kit Installation Instructions
To ensure safe and secure installation, please observe the instructions below.
WARNING
Do not attempt this alone!
At least two people are required to lift and position the dryer on top of a washing machine!
Failure to heed this warning can result in serious physical injury and damage to the appliance.
Secure the side bracket to the washer with a screw on the back of the bracket. Repeat Steps 2, 3, and 4 for the other side.
Place the dryer on top of the washer by placing the legs as shown. Be careful not to pinch fingers between the washer and dryer. Slide the dryer back against the stop on the side rail.
Stacking kit
Place the washer firmly on a stable, even and solid floor as product installation instructions describe in the owner’s manual.
Peel the protective paper from the tape on the side bracket.
Fit the side bracket firmly to the side of the top plate by attaching the double-faced tape to the top plate as picture shown.
7
Insert the front rail of the stacking kit. Push the front rail back against the stops on the side brackets.
Attach the front bracket to the side rails with a screw on each side.
•Do not use a stacking kit with a gas dryer in potentially unstable conditions like a mobile home.
Pedestal Installation Instructions
The pedestal accessory includes:
• Drawer divider (1) |
• |
Wrench (1) |
• Screws (18) † |
• |
T-clips (4) †† |
† Dryer installation only uses 8 screws
†† For dryer only
Tools Needed for Installation:
• Phillips-head screwdriver
• Wrench (supplied)
To ensure safe and secure installation, please thoroughly follow the instructions below.
WARNING
•Incorrect installation can cause serious accidents.
•The appliances are heavy. Two or more people are required when installing the pedestal. There is a risk of serious back injury or other injuries.
•Do not allow children to play in or on the drawer.
There is a risk of suffocation or injury.
•Do not step on the handle. There is a risk of serious injury.
•If appliances are already installed, disconnect them from all power, water, or gas lines and from draining or venting connections. Failure to do so can result in electrical shock, fire, explosion, or death.
•When installing, gloves must be put on.
Make sure the leveling feet of the dryer are fully retracted.
NOTE: The appliance and pedestal assembly must be placed on a solid, sturdy, level floor for proper operation.
Retract fully
Insert the T-clip of the 4 retainers into the dryer base as shown. Press up on the back of the clip and pull outward to lock into place.
T-clip
Place the dryer on the pedestal. Make sure the front and back feet are in the correct positions. The dryer feet will fit into the innermost positions as shown.
For dryer
For washer/combo
Make sure the screws on the pedestal align with the holes in the retainers, then install 4 screws on each side to securely attach the appliance to the pedestal.
NOTE: If the screws are not installed properly, noise and vibration may result.
Move the appliance to the desired location.
Loosen the locknuts on all 4 leveling feet of the pedestal until you can turn them with the wrench. Turn clockwise to raise or counterclockwise to lower until the pedestal is level and all 4 feet are solidly against the floor.
Raise |
Lower |
Securely tighten all locknuts by hand.
NOTE: Noise and vibration may result if locknuts are not tightened.
Be sure to connect the appliances to all water, power, or gas lines and draining or venting connections before operation.
If there is excessive vibration during the first operation after installation, slightly adjust the leveling feet.
