Removing and Replacing the LCD
Note: There are two types of keypad membranes. Depending on the age of the unit, it may be
a two-part membrane (LCD overlay + keypad membrane) or a one-piece overlay with integrated
keypad membrane.
To remove the LCD (4), proceed as follows (see Figure 4):
1. Carefully remove the LCD overlay or integrated overlay (1) from the fascia. (See Removing and
Replacing the Membrane Keypad.) Note that removing the overlay may damage the keypad.
Have a replacement available in the event damage occurs.
2. Use a No. 1 Phillips screwdriver to remove the four countersunk screws (8) securing the LCD
to the fascia. Retain these screws for reassembly. Each screw is held by a captive fastener
(5) which is integral to the LCD assembly. In earlier units each screw is held with a nut and
washer.
3. The keypad cable (3) and the LCD cable (6) may be secured together with double sided
adhesive tape. Carefully separate the harnesses and remove the LCD.
To replace the LCD (10), proceed as follows (see Figure 4):
1. Align the captive fasteners on the LCD with the four clearance holes in the fascia (2) and
reinstall the LCD using the four countersunk screws (8) retained from disassembly. The LCD
cable and the keypad cable are on the left side of the cover.
2. Carefully reinstall the appropriate overlay (1) on to the fascia. See Membrane Keypad Removal
and Replacement. NOTE: When applying pressure to the membrane to ensure the adhesive
bonds to the fascia, do not press down in the middle of the LCD assembly. Apply pressure in
the areas immediately adjacent the mounting holes only.
3. Secure the cables together using double sided adhesive tape.
4. Connect the keypad connector to controller board (4).
5. Connect the LCD connector to controller board (7).
6. Power the unit ON. If the LCD display fails to illuminate, or non alpha-numeric characters
appear on the display, the connector is improperly installed or the LCD intensity pot is not
adjusted correctly. Other symptoms of an incorrectly installed LCD connector may be a
flashing amber LED on the front cover or the solenoid valve activating repeatedly.
7. If the LCD intensity or contrast is not suitable, adjust the potentiometer labelled DISP,
on the controller board.
8. Reinstall the cover.
