I have a Genie pro99-IC opener, 6 years old. If has been working strange for the last few months. When you hit the remote to open is will strart opening super fast, and then slow down to a crawl and in the end only opening 3/4 of the way. You have to keep hitting the remote to finally get it to open completely. Well that was going on for the last few months but as of yesterday, it will function, as stated earlier(crazy) and then stop completely. No matter what I press it will not open. I need to completely unplug the unit and it will start up again, still not opening normal though. The unit has a little green light that flashes when it is in the state where is will not function at all. I feel the unit and it does not feel hot, so I don't think it is overheating but I am not sure. Any advice would be greatly appreciated.
Hi and thanks for choosing JustAnswer.com.weak spring tension, or birdnested lift cables will cause this behavior. Weak spring tension will cause the lift cables to slack enough to lift out of their grooves on the spool & tangle.Dual springs, one beside each track, wear out and get weak over time. Overhead springs can bind on the shaft, and sometimes break.Inspect your springs & lift cables & tell me what you find.

I checked the cables and they are taut and the spring is not broken however how can I check to see if the spring tension is good?
To check spring tension, with the door closed- disconnect the door from the trolley by pulling on the emergency release. Note the position of the release before you do this so when you go to reconnect, you will know what it looks like in the engaged position.Lift the door manually. It should not be heavy, and it should glide smoothly all the way to fully open.Tell me what you find. Easy, heavy, smooth, difficult?
I compared the ease of opening to my other garage door and I can lift both garage doors with one hand. So I would consider it to run smoothly. Do you have any other suggestions?
Yes I do. Try increasing the opening force adjustment. Remove the light lens. The force adjustments are behind it.
I did. Still not working correctly.
Having eliminated the physical possibilities, this leaves the logic board. It is responding to some imagined physical problem.When the "little green light flashes", count the blinks between pauses. Tell me how many blinks the code is.
I ran two - to three cycles with no issue then it started acting up. Going really slow up and crashing when going down. I even tried to pushing up when it was going up really slow and it did not help. Finally it stopped completely and the little green light blinked three three times. Thank you for you're help.
The blinks between pauses are a error code. Tell me how many blinks & I'll tell you what the logic board is thinking.The slow up, alone, points to the many things we have looked at. Now adding crashing down to that makes a big difference. This point to one thing only- a weak/defective motor. But let me compare/confirm that to the error code; I suspect it will agree.
The opener blinks three times between pauses.
The blink codes apply to the STB saftey sensors and it is the red LED that will blink 3 times = sensor receiving interference/ attemp to determine source of interference.I had hoped that your green LED blink on the opener was code & I still suspect it is. But there is no mention of it in the install manual under "troubleshooting".The intermittant nature of the behavior points to a loose connection somewhere on the primary sequencer board. About all you can do for that is look for a "cold" solder joint. They are grey instead of shiney silver.
