Genie 900 door operator

I think your garage opener has failed.

if nothing is obstructing the door then there are 2 possibilities:
a) your limit switch for closing is too low and the closer detects the motor stall as the floor is reached, then opens in case it's a kid under the door.
b) your tracks and garage door are mis-aligned, causing excessive force to trigger the reversal. Make sure the door closes easily by hand.

You have to pair the remote with the opener, which will require the opener manual because you have to put the opener in programming mode.

you can try to see if it works but probably no- get anather genie remote

you mean the ir beam is to wide? use tape..

UNPLUG RHE UNIT WAIT ABOUT 5 MIN. AND PLUG IT BACK IN.

THIS RESETS THE SEQUENCER.

SOMETIMES IT WILL SOLVE THE PROBLEM.

HOPE THIS HELPS

The problem is that the logic board has gone bad. If you don't have a logic board 900 joules or higher on these units get some. You can get a replacement board at genie.com. Thanks BB

If this is a Craftsman you need to remove the cover and you can then watch the limit switch assembly. If it is a Genie the up limit contact is probably broken

Sounds like a skinned wire on your front or rear limit switches is touching metal. Go over your low voltage wiring and test again.

to tell you how to fix this is tricky your limit switch is not working, if it is a liftmaster, or sears craftsman take the cover down, if it is a older allistar it is a dog limit on the chain, if a genie check the cherry switch in back of operator behind cover.
