Genie garage door opener opens but won't cloe the door

This is an older unit that doesn't have all those sensors. I can manually close the door and push the button to open the door but when I try to close the door it doesn't do anything.

My first guess would be to check the down force setting. If the setting is too light it won't close. Increase the force setting. You may want to also check the open limits & make sure the opener is not drawing the door open too far & getting the trolley jammed on a rail bolt.

You mention that the opener works fine on the open cycle and the door works fine manually and doesn't have photo-eyes...which leads me to believe (if the down force & limit setting doesn't help) that the logic board my be bad.

Since the opener is over 17 yrs old it may be difficult to get a new logic board. Even if you do find a logic board it may not be worth it. A logic board can easily cost $70 - 90. You can pick up a Craftsman (junkie but they do the job) for $140 - 160 from Sears. It can be hard to justify putting that type of cash into an old opener sometimes.

I think you can change it with a new one.

Check your down force. I will say that is the problem. At the minimum, start with that and eliminate each item as you go...

if you are having problem regarding, repair it..

I too have an older Genie model G5050 that does not have down force adjustments just the old clutch style. The door opens fine stops when it hits the open switch mounted on the screw drive, but will not reverse the motor and close. There are safety beams, but those are aligned and seem to be working fine. The close switch wiring looks fine too. I am baffled, but don't want to call a repair man for a door opener worth less than the service call will cost me. Thoughts? Can I bypass the safety beam some how to check that it's working? The open and stop switch's are simple single wire grounds, so not much to check there, but maybe there is a way to test that they ground correctly? By the way I have two of these that are doing exactly the same thing.
