A broken light sensor board will typically result in the lighting working for a few moments after being
powered on before it then shuts down.
1. Light Sensor board circled.
This is always on the left
hand side of a multi-unit run
with the control box,
screwed to the underside
of the mirror flap with the
photocell locating in the
circular cut-out. It is plugged
into the top of the control
board.
2. Removing the screws will
allow the sensor board to
be removed for inspection.
The photocell (circled) can
be damaged prior to
installation; either or both of
the pins that attach to the
board may be broken.
3. The very occasional
problem that can occur is
the metal connector pins
within the plastic connector
housing are not fully pushed
in. This will show up by the
pins not being a uniform
depth at the open end of
the plastic connector
housing. This can apply
equally to either of the
corresponding connector
housings.
4. If the connectors are OK
but the photocell is
damaged the photocell can
be bypassed to get the
lights working while awaiting
a replacement light sensor
board.
5. The two pink wires can be
removed from the light
board by depressing the
circled terminal connectors
with a thumb nails or small
screwdriver to release the
wires. The exposed wire
strands can then be twisted
together to make a
connection, and if desired,
reinserted into one of the
terminals.
