Relay Board Replacement - Dimplex CDFI-BX1000 Service Manual

Relay Board Replacement

WARNING: Disconnect power before attempting
any maintenance or cleaning to reduce the risk of
electric shock or damage to persons.
CAUTION: If unit was operating prior to servicing
allow at least 10 minutes for lights and heating
elements to cool off to avoid accidental burning of
skin.
Tools required: Phillips head screwdriver
1. Remove the front glass by pulling it up and out.
Ensure that it is kept in a safe place during the
service.
2. Remove any media on the tray, and lift out the
tray.
3. Remove the Opti-Myst cassette in order to access
the relay board at the bottom left side of the unit.
For the CDFI-1500BX, only the cassette on the
left needs to be removed. If necessary, disconnect
the power supply wires from the cassette, as well
as the heater wire.
4. Remove the cover plate by unscrewing the four
screws that hold it in place. (Figure 1)
5. Disconnect the wires from the relay board, noting
their original locations. It can be helpful to take
a picture of the relay board before the wires are
disconnected in order to keep track of each wire's
place.
6. Unscrew the four screws that secure the board to
the standoffs. (Figure 2)
!
NOTE: On the CDFI-BX1000 with no MOD des-
ignation, these will instead be snap-in standoffs.
The snap-in standoffs will need to be cut, and the
new board will need to be installed using self-
adhesive standoffs.
7. Properly orient the new relay board and screw it
back into place.
8. Reconnect the wires in their original locations.
9. Reassemble the unit in the reverse order as
above
