Measure the height of your garage door.

Asked by Crusader January 9, 2021

Answers

I agree with couple of the answers in here that size and weight doesn't matter as long as long the door was properly balanced, you can check by lifting your door by one hand it should comes up easy, continue to lift it up to just about your waist it should be able to balance itself with out dropping when you let go your hand. I have an old 1/2 house power screw drive unit on my 16Ft door for 18+ years and still going strong.

Asked by JV December 12, 2020
3
Answers

Yes it will work without the battery but you should always have it installed. It actually uses the battery during normal operation to achieve it's maximum lifting force. Not using the battery will reduce the life of the opener. Of course you are paying for this feature so you might as well use it.

This garage door opener is much quieter than the previous one (21 year old). I wanted to upgrade since we only had 1 remote and with the previous unit being so old it was impossible to program new remotes. Instructions were easy to follow. I installed it by myself which made installation take longer than I expected. I wish Chamberlain would include a little more hardware since every installation is different. I had to supply https://www.homedepot.com/p/Everbilt-1-1-4-in-x-36-in-Zinc-Plated-Slotted-Angle-800067/204225792 The set up for MyQ/wifi was straightforward. I would recommend people to buy the Chamberlain C450 model. Unfortunately Home Depot didn't sell this model when I purchased mine. It's the same capacity as C273 (1/2 HP), only difference is that the C273 comes with a battery back up, which to me is not important. The C450 comes with two remotes and a keypad.

Great garage door opener. Extremely quiet and WiFi capability works well on phones. Definitely a great buy. Highly recommended.

A surprisingly quiet opener with just the features you need. Includes basic Wifi using the myQ s...
A surprisingly quiet opener with just the features you need. Includes basic Wifi using the myQ system. The first thing that comes to mind is that this opener is surprisingly quiet. It is quieter than my 12 year old belt drive which was the quietest opener on the market at that time. Although quiet, the sound does vary a bit, and has more “whine” and less “growl,” which may draw some attention. The next thing I notice is that this opener has all the features you absolutely need, but you *may* want a few more. It comes with a secure remote, and secure manual wall button. It has Wifi ability so you can monitor and control in a very basic way from your phone. Finally, it has the important battery backup which is becoming a code requirement in many places. The backup works very well. I’ve had Chamberlain’s version of this on my last openers and I found it to be a real back saver when you need it the most. What it doesn’t have, however, is a second full sized remote, a motion detector wall button (to turn on the light), a keyfob remote, and an outside keypad remote. And maybe that’s OK! You can purchase separately what you may want, or go with a different upscale model that has all those. Of the above, the one thing I miss is the motion detector wall button. It really is nice to have the light turn on automatically when you walk into the garage. One more thing, this unit only has 1 bulb and not 2. Too bad, it would be nice to have 2. All the mounting brackets and size of the machine were compatible with my 12 year old Chamberlain unit. That’s a plus. The Protector System (safety beam) was also compatible. All other parts were installed as they were different from the older system. Unfortunately, the wall button and remote on my 12 year old system were “Security+”. These are NOT compatible with “Security+ 2.0”, which this unit uses. Security+ 2.0 is relatively new, so beware that your old openers may not be able to work. And, yes, that includes the wall button. The wall button sends a security code too, so any old doorbell button won’t work. The wall button has a side button to only turn on the light, if that is useful for you. This button is also used to program WiFi so you don’t have to get on a ladder. Speaking of remotes, the range on this one is huge! It is at least double of any other opener I’ve had. I can push it from a few houses away with no problem. Assembly had a lot of steps, but the instructions were very clear with good pictures. The difficult part is installing it using the provided hangers. You have a lot of measuring and you must get things aligned just right. For the ceiling, you may need extra straps depending on your ceiling height. I tried out the Wifi myQ system, and it is OK. I am going to remove it from my phone and disassociate my MAC address from the router because I just prefer to not have that info at a remote server. If you like this kind of thing, be aware it has basic capabilities. It can tell you the door status (up, down, stopped). It can open or close the door. And it can send programmable notifications (for example, if your door opens). Anything else such as hooking it to smart speaker requires more work and possibly a monthly fee. Likes: - Quiet for a chain drive - Enough power to lift a 1 car wood door - Secure remote - Very long range on the remote - Mounting points compatible with older versions of Chamberlain openers - Safety features work well Dislikes: - Misses a few nice features, like motion detector light - Only one light bulb, wish it had two - Recommendation to not install LED bulb due to radio interference - Not compatible with Security+ (last generation of Chamberlain openers and remotes) Made in Mexico

I just installed this Chamberlain Model C273 Smart Garage Opener on an insulated 2-car garage door. I was a little worried of how loud it was going to be since there is a bedroom located directly over the garage. All the chain driven garage door openers we have owned in the past have always been quite loud and I assumed this one was going to be no different. Boy was I wrong. This chain drive is just about as quiet as our belt driven one. This Chamberlain garage door opener has an app that you can download so that you can open and close the door remotely via your cell phone. You also get a text anytime the garage door is opened or closed which is fantastic. I also like that there is a little picture on the app that shows whether you garage door is open or closed. This is great for those moments when you leave the house and can't remember if you closed the garage door or not. Now all you have to do is open the app and verify the picture showing it is closed. This opener comes with (1) 3-button remote, (1) wall control, (2) safety sensors & battery backup. Battery backup is now mandatory in California per SB-969 due to all the recent wildfires. There were several people who were trapped in their garages with no power to their openers during the wildfires so having a battery backup is now mandatory. The battery is said to last between one to two years so you will have to replace it periodically but that is a small price to pay for safety. This opener comes with a 6 year warranty on the motor and a 1 year warranty on the chain. I've had several Chamberlain garage door openers over the years in all the different homes we have owned and they have been very, very reliable. I don't foresee this one being any different. The instructions for installing this opener were fantastic. It took about one hour to install since I was able to use the old mounting bracket for attaching the motor to. There are also YouTube videos people have posted that can help with installation if you are a more visual person. All in all we are very, very happy with our new Chamberlain opener. It is pretty cool that even garage door openers now have tech added to them. It makes a big difference. If this opener is anything like all our previous Chamberlain openers we will get years and years of use out of it. It is not uncommon for these openers to last 20 years or longer.

Only garage openers we use are Chamberlain. Have never had any issues. This one is 1/2 HP with wifi. Our other one is over 5 years old but is 3/4 HP and no wifi. My husband installed this himself, but he did suggest it would be easier with two people. Instructions are written very clearly. It's quiet and it slowly lifts our insulated 9 foot wide garage door with no problem. Everything connected and worked flawlessly first time. It has a battery backup so you can access even if the power goes off. One year warranty on the chain and six years on the motor. I like the myQ app you download for your phone. You can open/close the door, get alerts when it opened or closed too. Great product.

This Chamberlain 1/2 hp chain drive wi-fi garage door opener is great for single or light weight garage doors. It is equipped with a backup battery for power outages. One feature is the ability to open or close with your smart phone whether you are home or not. It opens and closes quickly and is quiet, very quiet, for a chain drive. Installation was easy AFTER reading the directions, please read the directions before starting the install. My wife says she’s using her phone to open the door when it’s time to come in from the shop.
