1.  Remove the external ground connector’s 

screw, and connect the ground wire 
(green or unwrapped) of the power cable 
to the screw.

CAUTION

•  To connect the ground wire to the 

neutral position without through 
contact A (cabinet ground), contact 
a technician. This is not user 
serviceable.

•  Ring-type terminals are remended. If 

using strap terminals, make sure they 
are tightened.

2.  Loosen or remove the screws from the 

center terminal block.

3.  Connect the neutral wire (white or 

center wire) and ground wire (white) to 
the center screw of the terminal block. 
Tighten the screw.

4.  Connect the other wires to the outer 

terminal block screws. Tighten the 
screws.

5.  Tighten the strain relief screws.
6.  Insert the tab of the terminal block cover 

into the rear slot of the dryer. Secure the 
cover with a hold-down screw.

WARNING

•  All U.S. models are designed for a 3-wire system connection. The dryer frame is 

grounded to the neutral conductor at the terminal block. A 4-wire system connection 
is required for new or remodeled construction, mobile homes, or if local codes do not 
permit grounding through neutral. If you use the 4-wire system, you cannot ground the 
dryer frame to the neutral conductor at the terminal block.

•  Remove the terminal block cover plate. Insert the power cord with a UL-listed strain 

relief through the hole provided in the cabinet near the terminal block.

•  A strain relief must be used. Do not loosen the nuts already installed on the terminal 

block. Be sure they are tight. Use a
