Issue Experience Cause
Remedy
Motor is not driving
/ corner is not
lifting.
Motor cable
connection has
come loose.
Check all harness
connections at the
controller, motor and limit
switch. If confirmed okay
and still no operation,
contact Jacka Industries
for advice.
Motor is driving but
not lifting.
I can hear or see it
spinning.
Loose connection
on the drive
coupler.
Ensure the drive coupler
between the motor and
drive tube actuator is
sufficiently tight.
Uneven roof
heights when
lifting.
Motors will drive at
the same speed if
each corner has
similar weights.
Hence heavier
corners will drive
slightly slower. This is
okay if the system is
still operating, and
the roof height will
level out at the top.
Ensure that the roof weight
is evenly distributed across
all 4 corners
where possible.
