press of a key fob button.
Although the unit is not
responding, can you hear
the control unit click when
trying to execute an up or
down command? On the
control unit does the red
motor light (1st light) flash?
If trying to send a command
from a key fob do you hear
a click and the motor light
and Prog light flash?
The fuse within the plug has
possibly blown and needs to
be replaced.
Remove the front cover on
the control unit and check
if the red light beside the T

is on.

is active, each time a
programmed control

indicator lights 1,2,3 and
the Prog start flashing for 2
seconds.
