Well I called Genie. They have the greatest customer service I have seen anywhere. Anyhow, after testing everything they narrowed the problem down to a stripped coupler assembly, a thing which grabs the screw drive and rolls it back and forth to raise and lower the door located inside the motor assembly. I wanted to post this in case anyone else has a similar problem. They are sending me one and hopefully all will work again. I just wanted to compliment Genie and recommend them both for a long working product and great help when it gets older.

Not sure if my problem is similar. I have a Genie screw drive that will not opne, only shut. Only when I disengage once and engage again, I can then open it.

I have exactly the same problem as areddy. If I close the door far enough that the 'closed' sensor switch is tripped, the door will not open unless I disengage enough to un-trip the sensor, then it will open.

I assumed it was the fault of the sequencer board since that's the board that reads the sensors, so I replaced it at a cost of $55. I still have the same problem.

I am at a loss as to what else it could be--it doesn't make sense that it would be the RF board. HELP!

The good news: IT'S FIXED!
The bad news: It was my fault :-(

Here is the fix: On top of the wall mounted switch there is a small slider switch marked "lock". That's right, it was locked--I wasted $55 on a new sequencer board. I hope maybe this helps someone else as that lock switch is very easy to accidentally move when you're groping around trying to find the button in the dark.

First always make sure the manual string is in the up position if not you have it set to manual open. Second you can test to see if the garage door is balanced what this means and can cause the door to not open all the way is some doors have 2 springs one on both sides new doors have one big spring at the top of the door this spring makes the door easier to open when the spring wears out the door gets harder to open hence the door is heavier, the genie garage door opener has a sensor inside of it which will turn the motor off is it senses the door is to heavy this is a precaution so the motor doesn't burn it self out. So this may be a possible cause of the door not opening in order to test this just engage the manual string pull the door manually up about 3 1/2 feet off the ground and let it go if the door stays still the spring is in good shape if it falls back down to the floor the spring needs to be adjusted (by a dealer) or replaced. Sometimes extreme weather like cold can effect the spring hence making if out of proper balance hence making the door heavier which will trigger the sensor in the garage door motor to stop at a certain point bacause it doesn want to burn it self out. So you can try taking a portable heater and try to warm up the spring a little along with lubricating the spring with oil or silicone lubricant if it hasn't been done in a while. Next if you find the spring is the issue you can always increase the power to the motor by opening the light panel (thats wear the light is housed) and in ther you'll see 2 black knobs one says open the other says close if you turn the open knob clockwise a little more that will increase the power of the motor when opening the door. But in this case you should only do this for a short time and eventually have some one like a Genie dealer come by and adjust the spring.

Hi everyone,

Can anyone here help me? I want a second garage door opener, but am not sure how it works. My opener says Genie 1/2 HP Screw Drive Medallion Series. I can't figure out which year it was made in, and can't find a model number, so I don't know what frequency it sends. All of the universal openers I find talk about only working with intellicode, or certain frequencies, or genie in only certain years. Can I get a tip on how to find out what kind of universal remote will work with my opener? Thanks a lot.

The Scredrive in my Genie 1/2 HP is sheared, causing the door to skip when it is closing. Is this screwdrive sold separately or do I have to bye the entire Unit?

The most common part to go bad is the carriage. You should be able to purchase one from any Genie dealer listed in the yellow pages.

GENIE Carriage Screw Drive 36179R.S/25589S

Genie screw drive carriage. Works with all Genie screw drive models made since 1970. This carriage has an embedded magnet in its frame to trip the excelerator magnetic limits. Otherwise, it is exactly the same model as the 25589S and will work for any screw drive unit that takes the 25589S carriage. The old part number, 34107R.S, has changed to 36179R.

To install carriage, remove the door arm from the existing carriage. Remove the nuts to the bolts on the screw drive rail to the front header bracket and slide the rail off to one side, giving room for the old carriage to be removed by sliding it off the end of the rail. Slide the new carriage onto the rail and replace the rail on the header bracket bolts and secure. Reinstall the door arm and engage the new carriage. Adjust limits, if necessary.

Mine did this also. I replaced the motor capacitor. It works fine now. It's very easy to do. Unplug the AC to the unit, remove the screws on the housing, replace the capacitor. This can be done without taking it down.

I have a Genie 1/2 HP screw drive opener that stopped working. When I press the button it hums and clicks. Can someone advise me as to what the problem might be? I don't see a serial number but it about 10 - 15 years old.

House was struck by lightning 2 weeks ago while door was closed, and my Genie 1/2 HP Model IS550/A screw drive purchased about 10 years ago has not worked correctly since.

At first, neither wall switch nor remote initiated any action. Days later I manually released the carriage from the track and raised the door manually to take out the garbage cans.

Then pressing the wall switch started the motor, which would not shut off even after I unplugged it, reattached the carriage and plugged it back in.

I ordered a new sequencer printed circuit board and replaced it.

Now, as the OP stated in this thread title, my door will close correctly, but will not open. Attempting to open it starts a loud grinding noise and the motor continues to run until I press the wall switch. Pressing it again yields the same results.

RE: "Here is the fix: On top of the wall mounted switch there is a small slider switch marked "lock". That's right, it was locked--I wasted $55 on a new sequencer board."

I do not have the original wall switch. I wired it to a simple push button doorbell type switch, so I have no "lock" setting on it to change.

So my question is there some switch or setting on the sequencer printed circuit board that I can change to tell it that I don't have a "lock" setting on my wall switch?

Thanks in advance for your help

Ordered new carriage for the screw drive and a tube of lube. Removed old carriage, saw teeth were chewed up, replaced it and lubed length of screw. Lubed all the rollers and hinges with WD-40. Works perfectly now and much less noise.

I have a genie pro screw drive garage opener and recently when I push the button it opens about a foot and closes. When I hold the button for about 2 to 3 secs while it goes up then it continues to go up. When I use my keypad it goes up a foot or so and back down. I have tried to research the sensor lights by covering them but this did nothing. GD closes without issue; it's only the opening. Any ideas?

Deatherage, you da man! Thanks brotha, I had the same problem and it was driving me crazy! Read your post and problem solved. Thanks again!

howlearner, I'm having the same issue and performed the research. Mine goes up if I hold the button down on the wall; but no luck on the remote; it raises a foot and back down. If I press the button on the wall or the remote and manually pull up the door it raises fine. So, this leads me to believe the spring tensions need to be re-adjusted. I hate to have to pay for a tech to come out and do it. Is this something a DIY can do?

I have a Geni Intellicode screw drive garage door opener. The screw drive has separated in one of the sections and I am trying to learn how to reconnect the coupler assembly? Any help or place here I can look it up, would be appreciated.

I AM HAVING ISSUES WITH MY DOOR OPENER IT STARTS TO OPEN THEN IT STOPS RATHER HARD AS IF IT REACHED THE LIMIT THOUGH IF I HIT THE SWITCH TO CLOSE THEN STOP AND HIT TO OPEN IT OPENS FURTHER THEN STOPS AGAIN AS IF IT HIT THE LIMIT THEN I TRY AGAIN AND IT OPENS ALL THE WAY TO THE LIMIT IT CLOSES WELL, ANYONE WITH THIS SAME ISSUE THAT CAN LEND A HAND IN TROUBLE SHOOTING THIS ISSUE? CAN NOT SLOW DOWN THE OPEN SPEED CLOSE SPEED WORKS.

Good evening everyone, still in the garage,can't figure out why, my genie powermax 1200 grinding,not open, found out the couple roundrounded out, I installed new one, but I set the force limits,when I pushed down button the door went about 3 in. Keep doing like that until it all the way down,but when I hit the up button it went fast until it hit the opener, try reset no luck, maybe circuit board???, I need help please,open about 4 years old, thanks

Hi I have a Genie Screw Drive Pro. Today there were some sparks in the motor area and then everything died. No power to the motor , the wall switch LED also is not lit. Do you all think that I need to replace the whole opener or is this something that can be fixed by replacing one of the parts like the capacitor or the circuit board(s) ?

I have a gene pro screw drive opener & quite often noise comes out of the gennie box . whats wrong
