Q: How to fix when the door opens instead of closing with the GDK 1100 motor?

Your problem is due to a polarity inversion of the motor. If the door opens (or goes up) instead of closing, and stops at the top instead of the bottom, the motor wires are connected incorrectly. How to fix: Reverse the two motor wires by swapping their connections at the motor (usually two red wires or one red and one black) Once the wires are reversed, you need to restart the complete auto-learning of the motor: Press the A button on the motor 3 times Press the B button once to start Wait for the door to complete its full cycle: it should go into closing , stop completely at the bottom, then automatically reopen and stop at the top If the cycle completes correctly, the learning is finished This polarity inversion is a known issue with Somfy motors. Once the auto-learning is completed after reversing the wires, your door should operate normally.

Your problem is due to a polarity inversion of the motor. If the door opens (or goes up) instead of closing, and stops at the top instead of the bottom, the motor wires are connected incorrectly.

How to fix:

Reverse the two motor wires by swapping their connections at the motor (usually two red wires or one red and one black)
Once the wires are reversed, you need to restart the complete auto-learning of the motor:
Press the A button on the motor 3 times
Press the B button once to start
Wait for the door to complete its full cycle: it should go into closing, stop completely at the bottom, then automatically reopen and stop at the top
If the cycle completes correctly, the learning is finished

This polarity inversion is a known issue with Somfy motors. Once the auto-learning is completed after reversing the wires, your door should operate normally.
