In brief:<\/strong> If a roller shutter motor does not run, the motor itself is often not to blame: frequently the thermal protection has tripped, the switch is faulty, an end position has shifted or the curtain is frozen. Only if there is power at the motor and it still does not turn is a replacement due.<\/p>\n

How to proceed<\/h2>\n
    \n
  1. Check fuse and switch \u2013 with radio, first the transmitter battery.<\/li>\n
  2. Wait a moment: if the thermal protection has tripped, the motor runs again after cooling down.<\/li>\n
  3. Check the roller shutter for blockages; in winter look out for ice in the guide rails.<\/li>\n
  4. A qualified electrician checks whether there is voltage at the motor.<\/li>\n
  5. If there is voltage and the motor does not turn: replace the motor.<\/li>\n<\/ol>\n

    Modern motors such as the A-OK AM45 radio tubular motor<\/a> have frost protection: they stop when the curtain is frozen instead of overloading.<\/p>\n

    Replace the motor instead of repairing it<\/h2>\n

    Tubular motors are sealed and are practically never repaired. A new motor costs from \u20ac65 net at A-OK (AM45 mechanical<\/a>). The steps are shown in Replacing a roller shutter motor<\/a>.<\/p>\n

    Frequently asked questions<\/h2>\n

    How long does a roller shutter motor last?<\/h3>\n

    With normal use, usually many years. Frequent continuous operation and overload from freezing shorten its life.<\/p>\n

    Can I still open the roller shutter?<\/h3>\n

    Nur mit Motoren mit Nothandkurbel, etwa dem A-OK AM45E<\/a>. Otherwise the roller shutter stays in its position until repaired.<\/p>\n
