SOURCE: Just installed a new genie garage door opener.

Change the sensor and make sure the magnet comes close enough to activate it. Sometimes I have even changed the magnetic ones for real switches too.

Use the emergency release handle to release the door. Run the opener to the open position until it stops. Close the door until it stops. Now re engage the the door.

Sounds like a problem with the safety photocells, to confirm locate the where the safety input is on the opener and bridge out the terminals ( not the supply voltage terminals) if the door then closes the photocells are the problem.

Genie excell garage door open's sooo slow and then stops 3/4 of the way up. Wom't move when instructed to close DOWN. Blinks 7 times in green on indicator light- so Can I trust that it is the Limit Switch...

Use the pull cord and disconnect the opener from the door. Operate the opener and let the carrier slide back away from the door. Is the carrier moving smoothly when disconnected? Next, lift the door by hand from the bottom to the top. Is it moving smoothly? If not, lubricate the axles of all the rollers on both sides of the door. Check the cable pulleys at the top sides of the door channel, lubricate them as well. Are all cables in all the pulleys, there are 4. After checking those things, there is a "up force" and "down force" adjustment on the opener, try increasing the "up force" by turning the adjustment in the direction of MORE force.

Garage door wont close completely

There are a couple of reasons this might happen. First make sure it closes by hand all the way, if not there is something wrong with the door that will need attention first. If it does close then hook the opener back up. On the opener rail at the end by your header there is a little magnetic relay that is wired to the motor head. This can be moved farther up or down the rail. This sensor tells the opener when to stop in the downward direction. Loosen the set screw and move it toward the header 1/2 inch or so and try to lower the door. Do not move it too much at one time and if you do the door will hit the ground and come back up. Thanks BB

Genie Directlift garage door opener, wall control problem.

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