Our PowerRise blinds started having problems going up and down. The motor started making loud squealing noises when moving. It seemed like the motor or gears were binding-up. I finally ended up taking the blinds apart, removing the motor, getting the motor specs and ordering a new motor from Ebay. The replacement motor fit perfectly. After re-assembling, it worked just like new...any much quieter.

The motor spec is: Copal DC Gear Motor LA16G-324SH, 50:1 300RPM, 12V (4.8-14.8V).

Also, years previously, the blinds weren't working, even after replacing the batteries. I found that the far end of the tube where the batteries are stacked was dirty and not making electrical contact. I put some steel wool on the end of w wooded dowel and stuck down the tube and after turning around and around many times and reinserting the batteries, things worked again...

 

Do you have a question about fixing your blinds???

 

I posted the info as an FYI because I couldn't find any helps from the internet searches I did when I encountered the problem. I wanted to post the solution in case someone else had the same issue with the blind's motor.

How do you remove the motor? Could you please send a picture. Thx

 

That is a combination motor and gear drive unit. The clip to the left of the motor holds it in place.

 

How you do remove the motor from the base?
Thank you

 

Using a small screwdriver at the yellow line..... lift that white tab up slightly and slide the motor to the right.

 

Great!! Thank you!
And on the other side of the base, Do I have to separate the plastic tube?
By chance do you know which remote control model pairs with this motor base?

 

No... I'm not sure what remote pairs with that operator.
The OP mentioned PowerRise but I don't see that listed on their site.

Not sure about separating the tube.
If the motor doesn't slide out then you may need to disassemble more of the unit.

 

Thank you for your hepl!!!!!

 

great analysis....great post.....my exact problem

Where did you buy the replacement motor?
I think the motor is out of production from
Nidec Copal.

I have six other shades and don't want to buy
a whole new set of blinds for one motor malfunction.

I'm having a very hard time locating the
motor or an equivalent replacement.

thanks for any help you might have

 

I left you a reply at your thread yesterday.

 

Many THANKS
I ordered two from Japan....only game in town.

the shipping was as much as the motor (1 or 2 units)
and now I should have a spare if I need another.

 

I'm having same problem with my hunter Douglas power rise shades and need to buy replacement motors (copal motor la16g-324sh). Can you please provide the link where you bought these at?
Thanks,
Brad

BradKan,
It looks like the exact motor that I used was discontinued, but it looks like this one is very close to the original and looks like it would work just fine...The specs are almost identical.
Robot MarketPlace - COPAL 50:1 Gearmotor - 12VDC

 

That's great. Thank you both for your helpful replies. I will investigate the alternative motor since it looks like the original one has been discontinued.
