Any codes/coupons to sweeten the deal?
NOTE: Used the 15off plus $3 off in shop rewards that just came out and bonus 25% points... Will replace a 20+ year Genie chain drive recently started to fail. But need new springs as the ones I put in about 8 years ago are a bit week. Opening the door halfway thru closes the door pretty fast. IRRC I just bought them based on the color of the existing ones instead of properly weighing them. PITA to change but did it once, so I can do it again...
I just put two of these up in our new build. Very quiet and easy to install. The first one took quite a bit longer to install as I had never put one up and the instructions were very confusing, to me anyway. I think they could have done a bit better with the instructions. The second one went up in about 2 hrs. I bought mine when they were on sale back in January or so for 199, I think. Then in March they went on sale for 169 +/- and I called Sears to get the new sale price. They didn't want to do it but I said then I'll just return and rebuy as they haven't been open and the manager said ok. I'd recommend this door.

yes, but this doesn't run on DC 24/7, obviously it's plugged into some outlet source for juice, even if that juice charges the battery. The motor is DC and will be driven by a power supply and/or motor controller built into the unit. When you lose AC power it is much simpler to control or drive a DC motor from battery power.
In general, I was researching couple of months back and guys at my home installed Belt Drive Lift Master, it is quite and my Chamberlain is like big tractor running, so Belt Drive indeed is good and battery backup comes very handy once in while. For me it happened only once in five years when I neeed it. Good deal.
speedy777 said: I heard the backup battery is useless because you don't loose power that often. When you out of power...the battery already dead. It charges the battery constantly. It even has a display showing how full the battery is, I just checked mine, it's 3 bars (out of 3).
I have seen it show less than 3 bars before, but that was only once and the power didn't go out at that time.
So every time my power has gone out, the battery backup has worked for me.
The battery back up is good and bad. I have one of these. It is a little older than the current model but works the same. My problem is that the battery goes bad. Even when never used. I installed mine about 3 years ago and I just installed the 3rd battery. Aftermarket batteries run anywhere rom $15-$75. I was told to simulate power outages in order to cylce the battery and it "should" last longer.

I don't see DC mentioned anywhere, but the motor is DC because when there's battery backup, it's probably easier to use a low voltage DC motor than a high voltage AC motor because a 12VDC-to-120VAC inverter would have to be rated for over 600W. OTOH the lightbulbs are 120V, even though 12V bulbs are readily available at every car parts store.
This is a quiet opener because all Chamberlain/Craftsman/Liftmaster belt drive units are made to be quiet. It's not the type of drive that determines the noise level but the motor, and the main factor in noise seems to be the brushes, which are enclosed to muffle them. Sears used to have an demo display in their stores that let people compare their belt drive and chain drive openers by operating the motors, but neither motor was attached to a chain or belt. Actually even the chain drive Chamberlains made now are quiet.
The batteries are lead-acid, just like the kind used in computer backup supplies, so they don't last long. Also some people have complained that failing batteries swell up and start dripping on their cars, despite the batteries being sealed and the openers having a plastic enclosure for the battery.
8' segmented track doors probably need an extension kit, about $45 from Sears or $27 from Sam's Club. OTOH many 1-piece pivoted 8' doors will open and close fully with just the standard 7' track.
Unit is SO quiet... Installed it over the long weekend... Couple of notes:
* Some items are packed inside the unit itself where the bulbs would go (the remote sensors and external wireless keypad) * Brackets for drywall ceilings are not included - you'll need to get one and corresponding mounting bolt/nut/washer to mount to the included brackets * Belt tensioner shown on the manual is different than what was packed. The online instructions (posted above) do correspond on how to properly install it.

One way to verify the tension of flat belts is by pinching the belt by hand, roughly midway between the pulleys, and twisting. A lot of belts will twist almost exactly 90 degrees when the tension is right.
Cycling the batteries shouldn't help, lead-acid batteries don't like to be cycled.
If you don't like the battery, you don't have to install it, it'll work fine without it.
This motor is "DC" because honestly, they're cheaper for the same performance now. This motor can provide speed when lightly loaded and it can step down in speed, increasing the torque when the door binds. AC synchronous motors only operate properly at one speed when driven directly off AC power as an normal-style garage door opener does.
This allows them to claim 3/4HP with a motor that doesn't nearly output 3/4HP nor consume the 500W it would take to do so. It provides the lifting capacity of a 3/4HP AC synchronous motor, but it has to step down in speed to do it. I never see mine step down except when running off battery.
Why are "DC" motors cheaper now? Because they are smaller. Smaller means less materials in it, which means less cost. It means less cost to ship it and the motors are always shipped from overseas now (whether the unit is Made in the USA or not). So the motor is a bit cheaper, but it's quieter and the speed controller/inverter required to drive it now is the same price or cheaper than the price difference between an AC synchronous motor and this smaller controller-driven motor.

I noticed that on this unit, after properly setting the open and closed stop positions (which are electronic and not mechanical trigger like my older model) it slows down when closing and before reaching the ground.
The panel does indicate the time and temperature and does mention code status like returned from power or battery charging. Very pleased with it and hope it lasts at least half of what the other unit I had lasted (25+ years).
Thanks. Just ordered one to replace a 20+year craftsman that is pretty loud in our new home. Hope the installation isn't too difficult. I've never installed one before. Any tips would be greatly appreciated!
