THanks, Im trying to get SI to atleast tell me what they use. Ill be calling them today before they close for the weekend.
Eppie is correct. You need to do some trouble shooting. Most motors these days are powered from a power supply and control unit. The former are much more likely to fail than the motor.
You need to ask SI to send you are service manual. When you know what circuits and voltages are involved you can trouble shoot it with a meter.
These days, I would bet that this unit is more complex than you think.
I have been on the SI site. That screen has a lot of options. DC rechargeable, 24 volt DC, and 120 volt AC. There are a lot of control options, the most common chosen is a suspect the Somfy RS-485 protocol. This screen can also be configured for SMART home systems.
Do you know what options your screen came with? This will be important for service. I note this was a very expensive screen.
I note they do have a button on their site to get expert service, but obviously I have no idea if there is anyone near you.
This unit is complex and would well beyond the scope of Best Buy to service.
I would say that it is actually unlikely the motor is the problem. You have bought a very complicated product, and unless you are experienced in electronic repair, you are not going to fix it.
So you need to contact SI for service. The made and sold a costly unit, so they have a responsibility to service it. Usually Best Buy are usually helpful in assisting you with service from the manufacturer. Talk to the store manager.
