I got a bft gate motor ; when i push the remote the gate motor wants to start but it turn a litte then stop i have change thecapacitor but still the same

check and test motor

Most garage door openers and I assume gate actuators have jumpers or settings if computerized to change frequencies.
Both the remote and unit will have to be changed.

It means that it has not programmed your new remote ie not compatable with your system or damaged hope this helps

It means that it has not accepted it ie not compatable or damaged taken too long to do the prcedure or wrong procedure hope this helps

The opener may have been mounted improperly or may have slipped from it's original mounting location. You may not be able to make an adjustment because the arm is already fully extended.
You may have to re-position the gate opener.
Fixya doesn't do repairs. Posting a question here is like calling the public library for an answer that they can look up.

Remove life gate Pannell and look at lifting motor and track . Seat on bac seat and push button and c why it is not working goodluc

well it seems like you have checcked almost everything. there are two things that come to mind that might be your problem, check the backup battery, messure it while on charge with a multi meter, the reading should be between 13.4v and 14.0v. if this is fine then if you have beams or loops installed try replacing them as they might be faulty.

your problem could be either photocells faulty or end of run connections miniatur reed switch or roker type next to the motor. i trust the motor is working? you can try to bridge the photocells connectors and also bridge the end of run connectors try one at the time and see how you get on ok?

The BFT site has an installation/programming manual for download.

It has charts of the codes and programming instructions.

Need more information.
Firstly, engage the manual release inside your motor and then operate gate by hand. Pay attention to any spots that are hard to push, this would indicate some sort of mechanical obstruction causing the motor to stop. Try remove obstruction.
Secondly, measure the voltage on your battery while trying to operate the gate. If your battery drops below 11.5V the control board will shut down. If so, replace battery.
