I installed in one of my clients, a craftsman garage opener that it was like horizontal with a light bulb on each side......man that was junk, he ended up getting his money back and bought the Chamberlain that is the same Craftsman I have, problem solved, so I am saying that you are right, chamberlain is the best, if you come across with a craftsman that you recognize is a chamberlain, buy it if its cheaper then with the chamberlain name on it.

the Craftsman/Chamberlain/Liftmaster are all manufactured by Liftmaster.....just labeled for where they sell them.....:D

Let me see if I can find it..............................

This is the best I found..........page 38

check on the motor housing or the ECU.......should be a schematic stuck on there somewhere......:thumbsup:

OK, I'll check tomorrow because I am already in my home...............Let me upload more photos

I think this will show why I need to invert polarity, sensors detect movement and instead of opening to avoid injury it really closes and can pin someone. I told my daughter Nicole to take this photos and send them to me...............

I tried inverting the motor wires that goes to capacitor (red and blue) and nothing, it only moves to one side now....closing wish on a normal USA gate will be opening.

What I'm going to do is, eliminate the sensors, so if a kid steps in it wont crush him............

I did elaborate good enough, let me explain again. I close the gate where the motor is design to open, meaning the trolley is all the way close to the motor, there I unplugged the power cord, I inverted the red and blue wires, replugged the power, when I hit the button what it did was trying to close the gate wish it was already closed ( tried to pull the trolley back.) Using logic now I think I have to invert something else not just the motor, maybe the wires where the plastic bolts are to adjust how far down or how far up. Or maybe at the back of the opener there are 2 more adjusting bolts with Kilograms icon.
You guys decide what should I try next.
If I wasn't clear enough let me know I'll explain again, it wont bother me, I recognize English is not my best and I'll start all over again if I have to. Trust me, it wont bother me at all my friends. and ty for all your help.

BTW, I check the board (ECU) and didn't find the schematic near it,

I wish I had a schematic of the opener, it would tell me what wires to switch.

Would those be the ones at the back with kilograms icon on it? Page 32 of the manual I up loaded, the black square with white dials.?? check it out page 32.

after looking at this manual turbo yes the limit switch is where you want to do the adjustments...without having or seeing how limit switch is connected to board you have a down contact which is brown wire and and up contact which is yellow these should be connected to wires on the board those to me is what you want to switch

Thanks my friend, I was thinking there is the problem, but do you think I should invert the polarity there and the capacitor to??????????or only invert in one place? ty

if there is dual windings on motor you wont be able to reverse it with swapping leads that way as Terryl has stated...the adjustments are going to be at limit switch...

Did you try to make adjustments with Force Controls and Limit Controls?



There's no difference if the garage are closing up and down or opening sideways (both are pulled and pushed) :tehe:

sorry I'm a reader and break everything first then fix it :okay:

The thing is the security feature of the garage openers is if the sensor detect something in the middle it will pull UP open the gate to avoid injury, in the style of gate I have if something its in the middle it will pull and this closes the gate injuring someone, a kid a pet or my mom. So I have to reverse the polarity so when this happens instead of pulling the trolley back up it pushes it far out where this type of gate it really opens, check the photos of my gate so you see it works opposite then the gate that rolls UP........The motor has being working flawlessly since we bought it and installed it, but really after 4 years it is getting on my nerves that will hurt someone, it has the security feature I just need it backwards for proper operation.............
