Genie Screw Drive not opening

I have a Genie Intellicode screw drive opener - probably about 12 years old. I had an issue where the door would open about 6 inches and then stop. After closing, it would happen this way a few time. Then it would no longe open, but the opener unit would hum twice. I checked online and found that the capacitor might be the issue. I replaced it. The door then opened and closed about 4 times. I left the house, but then when I tried to open it after coming home 4 hours later, I was back to the same issue.

Here's what I've done:

• Replaced capacitor
• Lubricated the trolley and screw
Disconnected the trolley from the door (but left it engaged to the screw) - The trolley moved up about 12-18 inches and then stops. If I hold the wall button down, the trolley will go all the way up. The trolley closes no problem. Again - this is with the trolley engaged but not connect to the door.
• With trolley connected to the door - the door only opens about 6 inches and then stops. If I hold down the wall button, the door will open about 3/4 of the run and then stop. It closes about the same - goes about 3/4's down and then stops - goes up about 3-6 inches and then stops.
• Inspected springs and side cables - all intact - door opens and closed manually with not too much effort
• Taken apart the motor - cleaned and rebuilt
• Unplugged unit for 1 hour
• Checked all wire connections

I've done everything I can think of and have found as possible solutions. I am about to replace the whole unit unless someone can provide some gem of insight.

Thanks for any help you can provide.

Sounds to me that the safety light sensors are either not working or are misaligned. The fact that you can hold down the wall switch and get it to travel leads me to believe this. To test, you disconnect the sensors from the brackets, string them to loose to the center and tape the sensors together. If the door operates, then misaligned, it the same happens, replace them.

Sensors

Thanks for the reply.

I like the idea of the problem being the sensors, but the door stops going down after the pulley/door travel 3/4 of the way down. Which could be a sensor.

However, I donít believe the sensors have any affect on the door going up if Iím not mistaken. Which I could be!

Arent the sensors there to protect for when the door closes? I am having issues in both directions.

In addition, I do have one green light and a red, which I know is correct for my opener as I have another installed on a second garage door.

I installed an opener for a client last month that gave me all sorts of grief troubleshooting. Had issues in both directions. I also had two good lights on the sensors. It was a 16ft door and the beam doesn't have to be off by much to cause issues. It took a good half hour messing and adjusting the sensors until they were lined up properly and the door worked. I was as frustrated as you initially, but in the end, was the sensors.

Okay, so I can say with near 100% certainty that it is not the sensors or the door.

To check this, I switched out this unit with the unit for the door next to it. It works perfectly now. I installed the bad unit on the other door, and it has the same issues. So I am fairly certain, unless you know something I don't, that the sensors and door/springs are fine.

Any thoughts?

Thanks again.
