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.

No, you don't have to use the keyless entry device. I didn't and my garage door works perfectly. The garage door opener company provides a third remote (wired), that is permanently installed on a wall for this purpose. There is really no need to install the keyless entry device.

Answer: 
All door openers at any "box" store will open 7' doors only. To open an 8' high garage door you need to purchase an 8' extension kit. They are sold in the same department as the openers and cost about 35-50 dollars more.

It does work on an 8 foot door, assuming the door is not too heavy. I suggest you contact the company directly to ask about weight requirements. They may suggest you up the hp to 3/4, but again, I think it depends more on the weight verses the size.

Rated 4.2 out of 5 by 307 reviewers.
Rated 5.0 out of 5.0 by Chamberlain took care of me when I had a problem I installed a Chamberlain 1/2 horsepower chain Drive 2 years ago when my old garage door opener gave up the ghost. it has been working great until a power failure. Strange as it may seem the remote worked but the wired door switch would not work. I called the Chamberlain hot line and she recommended several steps to take to be sure it was the switch. I checked it out and it was definitely the switch. Since I had a surge protector on the power outlet and it was less than the 2 year warranty, they sent a replacement switch right away, mean time I just used the remote to open and close the door. i replaced the door switch and it works great now.. They did a great job on he warranty replacement. DC June 3, 2016
Rated 4.0 out of 5.0 by nice find It was easy to install, and I only had to replace the main box, and wall control. The only problem with this product was instructions for reprogramming the remotes . One of my neighbors had the same one. They left in on factory settings like I did. When they left my door wood open. When they came back it opened once again. Reading the directions all three of ushad a problem with it. It needed to Specify to use the actual box that was installed to program it. Shows a picture of the wall Remote. So that was confusing. Works great now that we figure that out. Hope this helps you June 7, 2016
Rated 5.0 out of 5.0 by Best door opener yet Quiet, functional, love the wireless keypad, love the extra light....great value! June 21, 2016
Rated 5.0 out of 5.0 by I Don't Write Reviews Often, But This Purchase Was Smart This motor replaced a merik in my house in Panama. My 1/2 hp merik was purchased in 2008. I received a replacement price of around $875 due to my mountain location. After inspecting the motor closely, I noticed it was a Chamberlain motor that was re-named on the outside housing. To cut to the chase, I purchased this product in FL, transported it in my luggage, installed it in 2-1/2 hours with all new controls and keypads but using my existing rail system. It works great and saved me around $715 excluding tax. If you need to change a merik, this is a no-brainer. May 10, 2016
Rated 3.0 out of 5.0 by So Far So Good... I am quite pleased with my opener. I originally had a Chamberlain opener and it lasted for over a decade. This model is quiet and has many features. However, I was displeased with the fact that my local Home Depot in Eastvale, CA, wanted to charge me over 200.00 to install it, which I thought was outrageous. The installation cost was more than the actual price of the product. Insane!!! It makes you consider that next time when purchasing an item from Home Depot. I hired an outside installer who charged 100.00 and it only took them 1 hour to install. They did an excellent job and I could not be more happy. May 3, 2016
Rated 4.0 out of 5.0 by The Opener The unit was easy to install with another person. Adjustments seem to be easy to make. Still playing with minor adjustments for range of opening and closing. Makes a vibration noise when opening and closing. Can't figure out what that is right now. tightened the chain a little but it did not help. I like the keypad outside the garage. Disappointed that my homelink in my 2006 car will not sync up with the garage door opener. Car must be on a different frequency. Overall I love my new opener!!! May 17, 2016
Rated 3.0 out of 5.0 by It works..... and is OK So far so good, but we shall see how well this functions in the long run. This is a replacement for a Stanley garage door opener which was still working after nearly 35 years, but could, sadly, die at any time. I find the new Chamberlain opener to be much noisier than the old Stanley, which is rather disappointing as I had read that this model is very quiet for a chain drive. Not at all true. The Chamberlain has some features which were not available 35 years ago, so that is a plus, but all that I can say, is that it works and I hope that it continues to function properly for as along as our previous opener did. A number of user comments had indictated that this was quick and easy to install. It did not seem that way to me, although I was not the one doing the installation. It took my husband, an engineer, who has done this before, about 4-5 hours for the total installation. We have not attempted to use the Homelink as many user commments indicated issues with this feature. I would not give this product a glowing recommendation because it is very noisy but all that I can say is that it does open and close the garage door as it is supposed to do. May 30, 2016
Rated 1.0 out of 5.0 by Chamberlain will not help you, You have been WARNED The unit was not able to connect to the home link buttons in my 2007 Isuzu Ascender and the website www.bridge.chamberlain.com indicates that it this model garage door opener is compatible to my vehicle. I've written many times to customer service and they completely ignore what I say and tell me to buy the bridge. I tried to call them but after waiting on the telephone for an hour , I gave up. If I were you, I would not buy anything from this company. They will not give any customer service. May 21, 2016
