Doorking gate opener help/expert needed.

[bilede]

I have a Doorking 6050/6100 gate opener and slave (2 gates swing together to close) unit that have worked great for years now and nothing has changed but suddenly this morning they are out of sync meaning one opens and one closes instead of working together when remote is pushed.. Hoping there is an expert out there who can help direct me in how to fix the issue. Nothing online about these units and the manual just says hit the reset button and they will start working again. Obviously didn't work. have power cycled, pressed reset button, closed both gates manually then power back up, etc...

Anyone know how to fix or seen this before??

Are these the old ones with the rotary screw limit switches?

I do not believe so. Installed around 2005 and the manual says auto stops based on physical arm stops.

Post a picture of what you have. If it is electromechanical controls you just need to remove power from the slave, then cycle the master to match, then restore power to the slave. If it is a control board that uses a stepper motor to set limits, then you need to reset open/close limits.

Will get some picks in morning and post. Thank you.

removing power wires to slave, turning back on power, activating remote to make master same position as slave, then reconnect did make the unit open both gates simultaneously but then slave wouldn't close back. I flipped positive wires to slave at master circuit board so now slave generally stays closed and other works but obviously that is not a long term solution. Additionally, it appears I have no power on one of the slave motor terminals when activated. is there a reset or fuse maybe?

Thoughts?

I don't have a Doorking unit, I have a Chamberlain control unit and the motor control unit that is unknown brand. Your pictures didn't show any relays. The wiring show diagram shows a connection made for a relay(s) (two connections), if there are two relays, are they identical relays? If there is two relays, are they a pluggable type, if so, power everything down and swap the relays. Does the problem change or stay the same?

wiring show diagram doesn't show a setup for inground service loops or sensors? Do you have inground service loops or remote sensors?

 

[bilede]

no inground service loops or sensors. it has a liftmaster brand wireless remote attachment for the remote controls in vehicles to activate the door open and closed. that part works fine.

I see no relays but with "clear" cover I couldn't see everything so I took it off and have a better shot of circuit board.
