Yes! This unit has an auto reverse safety system installed. There are two trip circuits that will be installed at the bottom of your garage door (not on the door itself) on the garage wall. If the light beams are tripped, the door's operation will be ceased, and automatic reversal of the chain drive will occur.

Yes! This unit has an auto reverse safety system installed. There are two trip circuits that will be installed at the bottom of your garage door (not on the door itself) on the garage wall. If the light beams are tripped, the door's operation will be ceased, and automatic reversal of the chain drive will occur. This means that if the door is closing, and the light beam gets interrupted, the door will stop and return to the full open position. When the door reaches the full open position, you can re-trigger the door to close by simply pressing the correct button on your remote. Your pets have nothing to fear. Read Less

Answer: 
Should be a red handle attached to a rope hanging down near the center of the door. Pull down and back. Should detach the drive from the door allowing it to "free wheel". To reattach pull down and forward. You kind of have to get a feel for it. I would recommend getting used to it before you need it.

You may be interested in a battery back up system. These garage door openers will allow the remotes to continue to open and close your garage door even in the event of a power outage.

#1. The longer/coiled energy efficient bulbs don't see to fit as well (the bulb extends over the programming controls on the back of the opener)
#2. Use a 60-75W bulb - the 100w is very bright in a small room, but it also produces a lot of heat and I feel like it'll do damage to the plastic cover over time (ie. warp/melt).

The cover easily rotates down by pulling on the top of the cover; the cover even states "pull" on it. Once the cover pivots down you replace the bulb.

The Chamberlain Premium model # HD420EV houses two standard size bulbs; A19 incandescent (100W Max) or compact fluorescent (26W Max). Do not use halogen or LED lights. Since they are located inside the unit, a step ladder is most likely needed to reach them. They are accessed by pulling the translucent lenses down from the top while allowing them to rotate downwards. The covers are hinged so they will not fall off once loosened. It may take a bit of effort to pull them off as they are held by plastic fingers on both sides. Once the covers are down you simply remove the old bulb (if replacing) and insert the new one as you would for a lamp. Once inserted, you rotate the covers back up and push them until firmly back in position. Read Less

They use regular bulbs and you can also use energy efficient bulbs, and yes, they are easy to install. One thing I noticed, probably because I did not read the manual front to back. The light kicks on when you walk out of the garage door and through the safety lights at the floor level. These are the beams of light that allow the door to close or force it to remain open, based on something breaking the connecting beams (some no one or thing gets crushed by the door when it closes).
So if you are leaving the door open, I suggest you leave the garage by a door other than the electric door or be sure to step over the beam of light that runs across the door's path at the bottom, or the light will kick on and remain on until you turn it off at the inside switch pad or close the door again.

Rated 4.2 out of 5 by 324 reviewers.
Rated 5.0 out of 5.0 by Chamberlain chain drive This is the second garage door opener I've installed and the directions were decent making it easy for an average do it your selfer. I like the chain model because it's easy to adjust the chain if needed with the threaded bolt. With this model all you need is the Gateway hooked to your router to connect it which made it nice not buying extra stuff I didn't want. The only negative I have is Chamberlain not selling the upgraded control panel that has more functions unless you buy the Gateway along with it which I already purchased with this opener. Overall I'm very satisfied with the opener just wish it had more options to upgrade. Can't beat Home Depot's price and quick free delivery. August 16, 2016
Rated 5.0 out of 5.0 by Great garage door opener Easy to install, very quiet, good product and great value. August 16, 2016
Rated 1.0 out of 5.0 by Superior pain Our old garage door opener died after thirteen years of service. I did some research, read a ton of reviews. I went to Home Depot picked up this beauty got home, read the directions. Then later in the week I assembled the rail, and viola the chain was too short. I thought perhaps the rail was not together all the way. I checked and rechecked the rail but nothing was out of place or assembled incorrectly. I checked the Internet and found where they recommended purchasing a chain extension in the rare case the chain was too short. That told me they have had this problem before and that it was not so rare. So I boxed it up and took it back to Home Depot. I can not convey the enormity of the frustration this was for me. I think I would be perfectly fine opening the garage door manually for the rest of my born days than to have a chamberlain garage door opener in my house. Maybe it was this model maybe it was just this one box. I dunno but I DON'T RECOOMEND THIS PRODUCT EVER EVER EVER!!! August 12, 2016
Rated 2.0 out of 5.0 by Buyer Beware I intentionally bought a replacement chain drive opener from Chamberlain to replace an older chamberlain opener to ensure easy of use and install. The install wasn't too bad, but I couldn't use the existing reverse safety sensors, nor will the opener allow me to use my car's built in openers....It requires that purchase an additional compatibility bridge for the Toyota and a second "repeater" for the Ford. Still considering taking it back due to what I feel is the "nickle and dime" marketing tactic used by Chamberlain. August 2, 2016
Rated 3.0 out of 5.0 by Faulty Sensor I been having faulty sensor that wouldn't close the garage door. Called customer service no help and I still have to pay for parts even when it is under warranty. August 4, 2016
Rated 2.0 out of 5.0 by Won't puchase this brand again. Smart phone only works about 75% of the time. My family regularly has to get out of the car to open garage. Not compatible with Homelink even though website says it should be. July 31, 2016
Rated 4.0 out of 5.0 by Look Nice, Very Bright The glass covers are potato chip thin so they break VERY easily. I had to return to the store twice for replacements. The covers should be made of thicker glass or made of plastic. August 3, 2016
