Accelerometer Board Diagnosing

Check for 5 VDC from pin 1 to pin 4 at connector 

J901 on the accelerometer board.  If voltage is 

present, replace the accelerometer board.  If 

no voltage, check between pin 1 and pin 4 at 

J901 connector on the main board.  If voltage 

is present, check the harness continuity.  If no 

voltage, replace the main board.

Removing The 

Accelerometer Board

1.  Remove the control panel and top cover (See 

Control Panel

 and 

Top Cover

 sections in this 

guide for removal).

2.  Remove two Phillips-head screws securing 

the accelerometer board to the tub.

3.  Disconnect the harness connector from the 

accelerometer board.

NOTE

: There is a wire tie securing the harness 

to the accelerometer board that needs to be 

removed.  This can be done using a pair of 

needle-nose pliers.

Main Board Removal

1.  Remove the Top Panel (see 

Top Panel

 in the 

Cabinet and Structure

 section of this service 

guide

)

.

2.  Remove the two Phillips-head screws that 

attach the Main Board to the cabinet. 

3.  Slide main board toward the front of the 

cabinet to disengage the board housing tabs 

(one top center and two at the rear) from the 

cabinet.

4.  Disconnect the harness from the main board.

Slide Board

  Accelerometer Board

The accelerometer board is located on the top 

side of the tub directly under the cross brace.

 

The accelerometer senses when the load is off 

balance.  Upon acceleration of the basket during 

spin, the accelerometer sends a signal back to 

the main board.  This will cause the main board to 

stop the spin cycle and try to rebalance the load.
