Frequently asked questions

1. Door opener doesn't work with remote control:
• Is the opener connected to the power supply? If a lamp connected to
the power socket does not turn on, check fuse or circuit breaker.
(Some sockets are enabled via a wall switch).
• Are all door locks disabled?
See safety instructions!
• Does the control LED on the transmitter light up when the button
is pressed? If not, either the battery is empty, or the transmitter is
defective or too far removed from the opener.
• Try operating with a new battery.
• If you have two or more transmitters, of which only one works,
check programming of the receiver.
• Is there snow / ice under the door? If yes, the door may be frozen
onto the ground. Remove all obstacles.
• Perhaps the door spring is defective. This must be replaced by
a specialist.
2. Transmission range of the device is too low:
• Is a battery inserted? Put a new battery.
• Try radio control in the car at another location.
• The transmission range diminishes for metal doors, aluminium or
metal panels.
3. Door reverses for no apparent reason:
• Is the door hindered by anything? Pull manual release and operate
door by hand. In case of unbalanced or stuck gate, please contact
the service department.
• Re-programme operating power and stretch of way of the opener.
• Clear ice or snow in the closing area of the door.
• If the door reverses upon reaching the door position 'Closed',
the limit switch must be set for this door position.
After completing every setting, the automatic safety reverse
must be checked again:

In particular, the weathering can shift the doorway.
4. The garage door opens and closes by itself:
• Delete all transmitters and then re-programme them.
See „Programming of other handheld transmitters".
• Is the remote control button jammed in position „ON"?
• Use only original remote controls! The use of third-party products
leads to disturbances.
• The remote control button was pressed accidentally (pocket).
• Cable of the wall switch is damaged (remove for testing purposes).
• An accessory connected to the opener causes the drive (remove
for testing purposes).
5. Door does not close completely:
• Re-programme stretch of way of the opener. Check for alterations
in the mechanical components, e.g. door arms and fittings.
After each new setting of the door position 'Closed',
the automatic safety reverse should be checked for function.
6. The door opens, but does not close:
• If installed, the light barrier should be checked. If the LED at the light
barrier blinks, the alignment should be checked.
• Check transmitter or wall switch for function.
