I have a lift with an F3 Error which only occurs travelling down the rail. Going up it is completely normal. When descending it will go only about 8 inches before it stops with an F3 error. I have swapped the board… same problem. Checked the brushes…they are like new. Any suggestions?

Which version PCB T700 or earlier and have you measured the actual motor current?
From memory it used to be around 3A downwards and 7-12A upwards
Might be worth opening up the motor and hoovering up the carbon dust and making sure there are no shorts or damage across the segments of the commutator.

Thanks, I will give that a try. I have set the carriage aside and swapped in a replacement for the client. Have been waiting for some spare time to dig into the issue.

It is the T700 board…

Did you resolve this issue, i came across it a few times with T700 boards, it was down to a combinatiom of the track and board, try taking covers off and slackening the 17mm bolts that hold chasis together and doing them back up but not overtightening (obviously whilts on the track)

Have not resolved the issue yet but I will give the chassis bolts a try.
