Remote Receiver Board Replacement; Power Cord Replacement - Dimplex BLF50 Service Manual

REMOTE RECEIVER BOARD
REPLACEMENT
Tools required: Phillips head screw driver.
Needle nosed pliers.
Small cutter or snips
CAUTION: Follow "Preparation for Service" instructions
before proceeding.
1. On the top right side of the back panel, just below the
manual control switches, remove the 2 screws that se-
cure the upper control panel cover. Remove the cover
and set aside to allow access to the remote receiver
board wires. The board is the larger circuit board on
the left.
2. Remove any plastic cable ties to allow easier access to
moving the wires on the board.
3. On the remote receiver board, take careful note of the
original location of the wires.
!
NOTE: Some of the wires may have a "piggy-back"
connector that allows a second wire to connect to the same
prong as the first wire. (Two wires will connect on one
prong). Try and keep the "piggy-back" connection together
when pulling the wires off the circuit board.
4. Remove the wires off the receiver board. Pliers may
be required for grip when disconnecting the wire/spade
connectors off the board prongs.
5. To remove the board off the plastic mounts, cut or pinch
the plastic mounting tabs with snips or needle nose pli-
ers. Pull the old board off. Slightly raise the top of the
firebox off your flat surface and push the old mounts
out towards the back. Insert and push the new mounts
in from the back panel. Line up the holes on the circuit
board and gently press the new board onto the mounts.
Make sure the board is secure.
6. Reassemble in the reverse order as above.

POWER CORD REPLACEMENT

Tools required: Phillips head screw driver.
Needle nosed pliers.
CAUTION: Follow "Preparation for Service" instructions
before proceeding.
CAUTION: Follow "Instructions from Removing from
Wall" before proceeding.
1. Partially release the lower face panel. 5 screws in
total are holding the panel. (1) screw is on the left and
(1) on the right, inside the unit. There are 3 additional
screws located underneath the front face but do not
need to be removed.
2. If the 3 bottom screws to the front panel are accessible
in your application, you can remove them to obtain the
most clearance for the repair. If they are not acces-
sible, you can still proceed with them attached and
pulling the front panel forward from the top end by ap-
proximately 2" inches.
3. Remove the electrical junction box cover located on the
12
bottom right hand side by removing the 1 screw on a
small mounting-flange on the front face of the junction
box cover. Lift the cover out and set aside.
4. Remove power cord junction box by removing the three
Philips screws located on the, bottom left corner of the
fireplace. 2 screws are on the outer bottom panel and
1 screw is on the outer back panel.
5. Unscrew the 2 wire connectors that join the power cord
at the bottom to the wire leads coming down from the
top.
6. With a pair of needle nose pliers, open the strain relief
bushing that holds the power cord in place on the junc-
tion box and remove the cord.
7. Feed the new power cord through the junction box and
squeeze the new strain relief in place on the cord and
junction box. Re-connect wires. –(Wide blade on the
plug is the neutral side of the power cord).
8. Reassemble in the reverse order as above.
