5.0 out of 5 stars GENIE Excelerator is Excellent, December 31, 2007

By

This review is from: Genie ISD990-2X Excelerator 1/2-Horsepower DC Screw Drive Garage Door Opener (Tools & Home Improvement)

Installed the Genie Excelerator, 1/2 HP, DC Motor, with the fast open feature to replace my old screw drive Genie that lasted 15 plus years (the plastic gear on the carrier device wore out). Although I could have replaced this part, I wanted a full replacement to get the newer Intellicode feature (rolling code for security), better infra-red light system, as well as better overall operation. This newer Excelerator is GREAT. It is very, very quiet. The screw drive works well and, as I said, quietly. Only real noise comes from a little creaking of the garage door itself as it travels in the metal channels (something you really can't eliminate totally). This Genie Excelerator is noticeably more quiet than my old model. I really don't think you could get a quieter motor or opener with the dependability of the screw drive.

The screw drive is the same reliable system but with improvements to the mecahnism. The directions were very specific, but there was an enclosed yellow form notating a change in the wiring connections. Nothing complicated, just an update to the printed instructions and poster. At first I didn't think the screw type wiring connnections were as good as the old plug ins on my previouis system, but I decided they were really more dependable and easier to fix if need be. Although, I doubt it will be necessary as my last Genie was good for over 15 years! It takes a a few hours to get everything installed, run the wires to the auto-reverse lights, assemble the rails, and to get your ceiling mount lined up properly. But it is all well worth it.

My install worked flawlessly the very first time I tried the wall switch for the first operation. It was also very easy to program the remote controls by pressing the learning button and pressing the remote twice. And programming the HomeLink System in my cars was just as easy. The car owner's manual has the directions to program the homelink using the Genie remote that you've already set up, and then going through the "learn" process using the learn button on the Genie Excelerator. It was really very easy, and now I have the HomeLink buttons to use in my overhead car console plus the two remotes that come with the system for others. Also, the system comes with a coded outside opener to attach to the house. This has always been something we've used and the new remote worked easily with the same programming feature. This device is also better as it has a fold down cover for greater protection.

There are some fine new features like the wall switch with the red glowing lights to show the wall switches, the accelerated opening speed is very nice, the magnetic limit switches are a definite improvement over the old mechanical switches, the new carrier device uses a metal (aluminum?) gear instead of plastic, the slow down speed on closing makes for a quiet gentle closing process, and as I mentioned the remote programming with the newer Intellicode system is easy and much more secure than the old one code system I replaced. Genie really has enhanced the already strong quality and performance of its garage door openers with this Excelerator Model.

Overall the Genie Excelerator is the BEST garage door opener I've ever had and I recommend it to you highly.

Highly recommended ... the chainless screw drive is indeed quiet and the install was relatively painless - it can be adjusted to open quickly and close slowly - Great product.

4.0 out of 5 stars Excelerator Garage Door Opener needs mid-point bracing..., October 22, 2008

Genie Excelerator 1/2-Horsepower DC Screw Drive Garage Door Opener #ISD990

I installed one of these openers on our 7' high x 16' wide garage door in 2000.

Pros:

- After a power outage, the door raises VERY slowly, but otherwise, it takes just over 5 seconds.

- The infrared "safety beam sensors" at the garage door bottom were very susceptible to damage, being out in the open, so I protected them as shown in Customer Images.

- This opener has worked reliably for eight years (except as noted below).

- If I press the opener in my car when entering our 55' long driveway, the door is open by the time I get to the garage.

Cons:

- After about a year, the door would only go up a couple of feet, then stop. The 3-piece aluminum rail, which is a major weakness of this product, had been oscillating as the door rose; i.e., it would bounce up and down quite a bit. The rail just isn't strong enough. As a result, the rail sections eventually sagged where they join, and the screw drive sometimes didn't make contact due to that "bounce". The problem was solved by my installing mid-point bracing, which stabilized the rail so that it doesn't vibrate. See Customer Images.

- After 2 years, the "security" slide switch on the wall console stopped working. I called Genie and without asking how the switch was used, they said it was designed for vacations only, and not to be used on a daily basis. They've apparently had lots of switch failures due to "over use". However, Genie sent a free replacement wall "console", which includes that switch. After talking with them, I took the old console apart, and found a broken solder connection. I resoldered it, and that old switch is still working. I now have a spare console.

Other:

- If a garage door spring breaks, pull the door's rip cord to release the stain on the lifting mechanism, and have someone keep the door from slamming down if it's partially up. Forcing the opener to try to open a door with a broken spring could permanently bend or twist the aluminum drive bar, strip the gears, etc.

- If you have problems with the door getting stuck on the way up, liberally spread lithium grease on the drive screw. You should do that anyway, yearly.

Summary:

With mid-point bracing, I'd give it 3.5 stars (rounded up to 4). Without that bracing, since a customer shouldn't have to reinforce a new product, it's a 1 star device.
