Accelerometer Board - Haier GE GFW510SCN0 Technical Service Manual

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.

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.
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.
