Garage Door Openers – Reviewed
The course is currently under discussion….
There are different types of garage door openers, so which one is right for you?? The first thing you need to know, is that the garage door opener is not a one size fits all application. The door opener is designed to work better if it depends on the quality of the door, most of our repairs are done on machines that are installed incorrectly or the door opener is on the wrong side of the door, and usually just low. well opened.
Now so far I have used the words “opener” and “machine” both have the same meaning, they refer to all the machines so when I say “opener” I not about the equipment in your car.. .that is called “remote control” or just “remote control”. With that being said there are many types of garage door openers on the market.. there are screw-drives, there are chain-drives there are belt-drives and last but not least-drives which are usually called “Jackshafts”. But let’s take them one at a time and start with…
These machines have been popular (not necessarily good) on all types of doors for the better part of 45 years but … because of their design they need regular maintenance. Back in the 6Os, 7Os and early 8Os, Genie used very sturdy steel in the “carriage” or “trolley” and the machines were very tough! Even if there is no oil on the screw they will run for what seems like forever then they switch to a lighter metal grade and all that goes down, the openers will still go as long as one is out there giving for you regularly greased the nail but who does that. !! So the average life of a Genie screw-drive trolley is about 4-5 years and that’s generous, Liftmaster or Chamberlain or Craftsman, all made by the same mfg … (Chamberlain) also has the screw-drive and it has the same problem so that they use plastic trolley and self-lubricating housing around the screw to prevent heat and wear, but self-lubricating housing only lasts a year..or the equivalent of your warranty then it’s back to the same ol, same ol “grease-grease-grease”. My thoughts on screw drivers are… far from them, they are old tools with a new look to them.
This type of machine has been around for as long as the screw provided or used 5yrs and they have come along the way. Chain-drives have always been a very popular machine but caught a bit of a bad rap when Sears started selling a do-it-yourself model from Chamberlain called the Craftsman, now this machine, although the so-called “chain-drive” is driven by a machine. chain on one side and a cable on the other and it seems that nothing can be done to keep this quiet because the cable will stretch until it breaks the loop. So from then on the chain-drive started to get a bad rap as a “coffee-grinder” or a noisy machine, even though it wasn’t actually a chain-drive.
The Liftmaster 1300 series of chain-drive … dollar for dollar is as good a machine as you can get, they are versatile, in that they can handle everything from the door to the heavy wood to light steel, one-piece or sectional and they are powerful and cheap and also speak … less maintenance, but to get to this point they have had many good improvements in the way. Chamberlain added a chain that prevents the chain from colliding with the rail, changed the front sprocket to a pulley to reduce the noise, they changed out the steel cab gear to the nylon cab glass in the case to reduce the heat of the helical gear and they remove two tension springs from the trolley inside to reduce the door bounce and its one piece rail with all wrapped around see.
The equipment of this machine can work how the motor is released, so usually you do not need 1/2 hp to lift the door, and as far as routine maintenance the day goes on.. there is no good, there are only two nylons. glass in the motor body every 7 years and that’s about it, in the rare case where you happen to have a house on the beach and only use the opener in the summer so you can spray the chain with a good silicone. link of the white chain. Two of my favorite models that have really worked for us over the past two years are called # 1346 = 1/3 hp and # 1356 = 1/2 hp.
A few companies make use-drives today but I like to stick with the most reliable brand which for me is Liftmaster, we carry many brands but prefer to go with the light brands problem at least so rely on Liftmaster use-drive for now. Note that belt-drive openers are a special door mechanism, they do not work on 1pc doors very well or for very long and should NEVER be installed on 1pc doors. To keep it simple, there are two types of motor… AC and DC.
AC belt-drive model known as formula I, is one of the early belt-drive models and the main thing is its chain-driven motorhead which is driven by a belt. It is minutely quieter than a chain-drive minus the power and for me … not a good machine, but an easy one to sell because it is cheaper than a DC model and the public don’t know the difference, they just know. belt-drive must be top of the line and this is belt-drive, so they are not a genius for tricks, business owners can buy these machines in bulk Cheaper than their DC motors and sold for belt-drive (honorable) prices. What makes the “DC motor” belt-drive quiet is the motor! Also that’s why they even put it in DC, plus another benefit is the ability to have a battery back up so that it will run even if the power is turned off.
In its simplest form a DC motor produces more output than an AC motor and the horsepower for DC is in “Newtons” rather than HP but the DC motors also have a “slow start /slow stop” feature that helps to speed up the whole process. be quiet. When the AC motor works it goes O-60 or should I say “O to speed” in one shot… the second you push the button, but the door on the other side hands are not on the same page and need. to resist the power immediately and that is where the noise comes from. as a smoother motivator for the door to get it. go without all the jerky-ness, and it does the same as it comes to a stop, so for the first two fingers and in the last two fingers it slows down, greatly reduces the clanky-ness of the whole business.
DC machines also use electric power to measure the pressure needed to operate the door according to its resistance and weight,
that leaves little room for installation error, in other words, the installer can’t build a machine to hit your car hood or your cat, AC motors are at the mercy of the installer , if it sets the power switch too high, it crushes, if it sets it too low the door will bounce back on a cold or wet morning when you are happily driving to work without realizing that you the car doors will open every day and that spankin’ new Craftsman box you just got for your birthday is about to be sold for a fraction of the price it’s worth at the local barter meet….all because you thought you got a belt-drive door opener for a bargain price!! Final thoughts…AC motor belt-drive = bad (better with chain-drive) DC motor belt-drive = Very good, quiet, but special door. (Only works on spare doors)
Jack-shaft (Direct Drive)
This section is easy because there is only one available and its Liftmaster # 3800, and it only works on doors. So for those of you looking for a machine that doesn’t mount to the ceiling like a traditional machine, the Liftmaster #3800 might be what you’re looking for, it’s quiet, has (800 Newtons) or the equivalent of 3/4 hp and mounts on the end of the torsion tube giving you at least 10 inches of side clearance, so the idea behind this opening is that you have room above the garage, it removes all … that hangs from the ceiling, or if you have a low light in the garage that supports the second story of your house or has a door or the storage unit where the open door will be installed you can still use your door using this mode. machine.
It can also be used for applications where you just don’t want a hole hanging in the middle of your garage. electric, other The advantage of this machine is that it will lift the door up to 13 feet high without adjustment while the normal machine will lift the door up to 7’4″ with the machine railed normally you need to get a longer rail to fit in. the added height of say an 8′–9′ or 10 ft high opening which is becoming more common in newer buildings. The Liftmaster #3800 has been a reliable alternative for us since 2004.
Everyone likes options, but given the fact that when it comes to garage door openers there are so many options that it’s easy to choose the wrong one for your garage. car door that can lead to many future service calls and repairs. hopefully this can clear up a few things for you when it comes to choosing the right machine and you will have more “good” ups and downs with the right one.
