Legacy opener - can't set open / close limits

I have an Overhead Door (Genie?) Legacy 696 CD/B with chain drive.

I have read the manual.

Safety sensor LED's are solid red and green.

Manual says to press the limit switch (there is only 1) and the door will go up to set the open limit. It does go up.

It says to press the same switch again and door will go down and set the close limit. It doesn't do that. It travels open even further.

I have tried having the door at mid point on the track and the open and close fine limit switches in the housing at mid point.

I have tried having the door closed and the open and close fine limit switches in the housing at mid point.

Still will only open up.

Wall switch does not work, is unlocked.

Checked and reseated the wiring from the wall and safety sensors.

Would appreciate any ideas.

David

I did a similar job a couple of months ago. I think the light is supposed to be flashing somewhere along the line. I forgot the exact procedure. Maybe you have to hold the limit switch until the light starts to flash. IIRC a solid light is no good. I may talk to the customer later & I'll ask her to look at the instructions.

I could never get it to work either... look inside the two curved grooves on the back cover, there is a plastic screw you can turn to adjust up and down limits. you will have to be quick or unplug the opener when it gets close to where you want it to stop because the screw is moving.

An orange wire had come loose inside which solved most of my problem but getting the limits right is a pain.

Thanks all for the help.
