To test the sensor rod circuit:

Place the dryer in service mode and index to the rod voltage test.  The rod voltage, in hundredths of a
volt, shall be displayed on the DSSD.  Open the door and touch the rods with your hands and view the
DSSD.  The voltage displayed on the DSSD should diminish, indicating that the capacitor is discharging
properly.  No change on the DSSD indicates that either the rods are not connected to the board, an open
exists in the sensor rod circuit, or there is some other problem on the board.  When the rods are
released, the voltage displayed on the DSSD should increase.  The sensor rods come as part of the air
duct assembly.

Note: Wait at least 45 seconds before repeating the test to allow the capacitor to charge fully.

Electronic Control Board

The electronic control board consists of 2 circuit
boards connected by 2 ribbons.  The boards are
attached to the back of the control panel and
control all washer functions.  The boards are
replaced with the control panel as an assembly.

If a faulty board is suspect, check for continuity
across the fuse and visually inspect the surge
protector mounted on the board.  If no continuity
is read across the fuse or if the surge protector
appears burnt or damaged, replace the board.

Caution:

•

When replacing the control panel, remove
the protective coating from the overlay prior
to power-up to prevent ESD from damaging
the new board.

•

To prevent electrostatic discharge, ground
yourself to the washer cabinet or use an
ESD wristband.
