Welcome, I have a question about how to carry out diagnostics on a faulty roller shutter motor, where to start? Background: motivation + electrical meter - in a word not much. New 300 pln. I have two damaged ones. 600 pln makes a difference. So I decided to ask for help..... Pictures attached....

There are two relays on the board presumably to control the direction.You need to power it bypassing the control board. Maybe the relays have died and the motor is not getting voltage.

On the board (circled), You have cold solders clean them and correct them.

Good morning, please hold off on your own repair until Monday. We may be able to help you.

Sorry for digging up the subject. I have Mobilus drives on my external roller shutters and am experiencing a self-draining roller shutter; when I raise it almost all the way, it automatically flies down. If I raise it to its maximum level, it goes up and down by 2 cm until it stops after a while. Has anyone had this problem? Can it be repaired or is it just a replacement? Best regards

Sorry for digging up the subject.
I have Mobilus drives on my external roller shutters and am experiencing a self-draining roller shutter; when I raise it almost all the way, it automatically flies down. If I raise it to its maximum level, it goes up and down by 2 cm until it stops after a while.
Has anyone had this problem?
Can it be repaired or is it just a replacement?
Best regards
