They sent Doug Fussell out to my house on the day after Christmas! I had only called them three days before! Doug was a premier technician, very thorough and very efficient. I expected him to take two days, since he was replacing two doors and adding openers on each door. He only took the daylight hours of one day! I could not believe how fast he was! In addition, he thoroughly taught me how to use the remote openers. I highly recommend them to anyone!
The chain-driven Chamberlain C410's .5-horsepower motor has enough power to handle most residential garage doors. Owners say it lifts even heavy doors easily. While chain-driven openers generally are louder than belt-driven models, most say that, like its predecessor model, it's actually pretty good in that regard, and we saw fewer complaints about installation challenges, too. The opener is also well-equipped in the feature department, though you'll need to spend a bit extra if you want to use its smart functions.
As noted above, set-screw clamping may have distorted the cross-section of the shaft and made it difficult to slide off all the hardware. With the shaft on the floor, it may be possible to restore enough roundness to proceed, using compensating clamping force to the distorted area via a machinist's vise, an arbor press, a hydraulic shop press, etc., on the shaft body. Burrs and other slight distortions on the shaft can be filed off with a hand file or touched with an abrasive wheel on an angle grinder. At some point, the condition of the shaft may just be degraded enough that it ought to be replaced.
It is precisely on those coldest days of the year when you most need and appreciate the convenience of opening and closing your garage door quickly. Sadly, those also happen to be the kinds of days when cold and moisture combine to make this difficult. Garage doors can and do freeze to the garage floor. Sometimes it is a minor icy connection between the two that can be broken when you hit the opener button.
And for some extra features, you'll appreciate accessing the system through the MyQ smartphone app. You can set up this Chamberlain opener to automatically close the door after 1, 5, or 10 minutes, which is great for people who are a bit forgetful. We also really like the motion-detecting control panel, which turns on lights whenever it records nearby movement.
