Electronics; User Interface (Ui) Board - Haier GE UltraFresh GFD55ESSN Technical Service Manual

User Interface (UI) Board

The user interface (UI) board is mounted to the
control panel assembly under the plastic cover. It
consists of the display board; cycle select board
and the power/pause button board. They are all
connected together and come as one part.
NOTE: The cycle select knob does not need
to be removed as it will stay with the control
panel.
User Interface (UI) Board Diagnosing
The user interface (UI) board is powered by the
main board from the J601 connector. If the user
interface (UI) board is not working, check for
approximately 13.5 VDC from pin 2 to pin 8 on
the 10-pin connector from the main board to the
user interface (UI) board. If voltage is present at
the J101 connector pin 4 to pin 5 of the UI board,
replace the UI board. If no voltage, check the
harness and connectors. If good, replace the
main board.
User Interface (UI) Board Removal
1. Remove the control panel (see Control
Panel and Front RJ45 Access in the Dryer

Then place the control panel face down on a
protective surface.
2. Remove the single harness that supplies DC
voltage to the UI board.
3. Disconnect the RJ45 connector by pushing
in the tab on the connector. Then rotate the
connector from the control panel.
