Troubleshooting
Vertical lines on the LCD display when the dryer is
turned on. Re-seat LCD ribbon cable at connector CN6 on
the main board. If necessary, a piece of scotch
tape may be added to the back of the ribbon. This
additional thickness will provide better contact for
the ribbon terminals.
LCD screen too dark or too light as compared to
LCD washer screen. LCD refresh rate can be changed in Factory Test
Mode. (See Contrast setting.)
Touch screen pad activates an adjacent function
incorrectly, i.e. pressing one pad activates a
function of another pad. The LCD display ribbon connection on the main
board may not be secure. Check the connection
to make sure it is secure.
Checkerboard pattern in MY CYCLES screen. Electrostatic discharge on main board. Enter MY
CYCLES and press DELETE on the touch screen
LCD; this will clear the checkerboard pattern.
Possible Cause and Repair
Scuff marks on the plastic backspash or cover
(Platinum models). Can be removed by appliance polish, part no.
WR97X216, or a high quality of automotive paste
wax.
LCD backlight does not come on. The backlight connection on the main board may
not be secure. Check the connection to make
sure it is secure.
Problem
Can occur when LCD screen is replaced. New
LCD screen must also be set to inverter output.
Adjust the refresh rate through the
Factory Test
Mode. (See contrast setting.)
Replacement LCD screen too dark or too light.
