Liftmaster strongly recommends
using an LCD wall control with
the operator.
If the wall control is intentionally
disconnected, this error can
be cleared by placing a jumper
wire between the WALL CTRL
teminals on the powerhead main
board. If the jumper is removed
and a wall control reconnected,
the system may require a power
cycle to recognize the new wall
control.
If LCD wall control isn't
functioning properly, see
diagnosis for fault 'LCD wall
control is off or not functioning'
