If your Assa Abloy Garage Door Opener motor isn't starting and the door won't open, it could be due to several reasons. First, ensure the program selector isn't set to OFF; if it is, change the setting. Check the motor cable for power, verify the high voltage power supply, and replace the fuse if it's blown. Also, examine the activation unit and strap the impulse inputs if it's not functioning.
