Garage Door Openers – Reviewed

Class is currently in session….

There are several types of garage door openers, so which one is right for you? The first thing you need to understand is that garage door openers are not for everyone. Garage door openers are designed to work better when it’s on the right type of door, most of our repairs are on machines that are either installed incorrectly or the opener is on the wrong type of door and in many cases it’s just low. quality opener.

So far I’ve used the words “opener” and “machine” which have the same meaning, they refer to the whole mechanized operation, so when I say “opener” I’m not referring to the hand-held device in your car. .it’s called a “remote control” or just a “remote control”. As a result, there are several types of garage door openers on the market. There are screw drives, there are disc drives, there are belt drives, and last but not least, direct drives, commonly referred to as “Camshafts”. But let’s take them one by one and start…

Screw drives

These machines have been popular (not necessarily good) for all types of doors for the better part of 45 years, but…due to their design, they require regular maintenance. In the 6Os, 7Os, and early 8Os, Genie used very durable steel in the “wagon” or “carriage” and the machines were tough! Even without grease on the screws they would last forever, then they went against the lighter steel and all that went downhill, the openers would still last as long as anything if you greased the screws regularly, but who ever does that. !! So the average life of a Genie screw driver cart was about 4-5 years and that’s generous, Liftmaster or Chamberlain or Craftsman, all the same manufacturer… (Chamberlain) is also a screw driver and has the same problem to prevent them from using a plastic inner cart and a self-lubricating body around the screw to keep heat and wear at bay, but the self-lubricating body really only lasts about a year. or equivalent to your warranty, then the back of it is the same, the same “grease-grease-grease”. My official opinion on screwdrivers is…stay away from them, they are old tech with a new look.

Disc drives

These types of machines have been around as long as screwdrivers give or take 5 years and they have come. Disc drives have always been very durable machines, but got a bit of a bad rap when Sears started selling Chamberlain’s do-it-yourself model called the Craftsman, but now ran this machine, even though it’s called a disc drive. chain on one side and cable on the other and it seemed like nothing could be done to keep the thing quiet as the wire stretched until it broke at the loop. Since then, chain drives started to get a bad rap as a “coffee grinder” or a noisy machine, even though it wasn’t a real chain drive.

Liftmaster 1300 Series Disc Drives … dollar for dollar are as good a machine as you can get, they’re versatile as they can handle all types of doors from heavy wood to light steel, one piece or sectional – and they’re powerful and cheap with relatively little… with maintenance, but they’ve had a lot of good improvements to get there. Chamberlain has added a chain spacer to keep the chain from hitting the rail, swapped the front sprocket for a pulley that greatly reduces chain noise, changed the steel worm gear to a nylon worm gear inside the housing to reduce heat from the helical gear, and they removed two tension springs from the internal carriage to reduce door bounce and its strong one-piece rail with chain all around.

The components of this machine can handle what the motor puts out, so in most cases you don’t need 1/2 hp to lift the door and as far as routine maintenance goes. the gears inside the motor housing are lubricated every 7 years and that’s it, on the rare occasion that you happen to have a house right on the beach and only use the opener in the summer, you can spray the chain with a good silicone to keep the links free on the chain. The two models that I prefer and have been real workhorses for us over the past two decades are currently #1346=1/3hp and #1356=1/2hp.

Belt drives

Many manufacturers make belt drives these days but I like to stick with the most trusted brand which for me is Liftmaster, we sell most brands but we prefer to deal with the brand that has the fewest problems so we focus on Liftmaster belt drives. now. Remember that belt drive openers are a VERY door specific machine, they will NOT work very well or very long on 1pc doors and should NOT be installed on 1pc doors. To simplify, there are two types of belt drives… AC and DC.

The AC model belt drive, known as the Formula I, is one of the earliest belt drive designs and is essentially a chain drive motor head that drives a belt instead of a chain. It’s a bit quieter than a chain drive minus the power and to me… not a good machine but it’s an easy sell because it’s cheaper than the DC model and the public doesn’t know the difference, they just know belt drives are supposed to be top of the line and it is a belt drive so they are none the wiser for gimmicks, dealers can buy these types of machines much cheaper than their DC motor counterparts and sell them for a belt. drive (surcharge) price. What makes the “DC motor” belt drive quiet is the motor! Otherwise why would they even offer it in DC, plus another advantage is the ability to supply a battery so it runs even when the power is off.

In its simplest form, a DC motor produces more torque than an AC motor, and DC horsepower is rated in Newtons, not HP, but DC motors also have a “slow start/slow stop” feature to help keep all the work going. silent. When the AC motor is activated it goes O-60 or should I say “O to full speed” with one stroke…the other when you push the button but the door is not on the same page and wants to resist the sudden force and that’s where a lot of noise comes from.. basically it’s the jerk of the door resisting the opener where the slow start of the DC machines acts as a smoother motivator to get the door to go without any jerk and does the same as it stops so for the first two inches and the last two inches it slows down greatly reducing jerkiness of the whole operation.

DC machines also electronically calibrate the pressure needed to operate the door based on its resistance and weight,

which leaves little room for installer error, in other words the installer can’t set the machine to smash your car hood or your cat, AC motors are at the installer’s discretion, if he sets the force control too high it will crush, if he sets it too low, the door will pop on a cold or wet morning back when you’re happily driving to work, unaware that your garage door has been open all day and that brand new Craftsman toolbox you just got for your birthday is for sale at your local swap meet for a fraction of what it’s worth…all because you thought you could affordable belt drive garage door opener!! Final thoughts… AC motor belt drives= not good (chain drive is better) DC motor belt drives= Very good, very quiet, but very door specific. (Only works on sectional door)

Jack shaft (Direct drive)

This section is easy because there is literally only one available and that is the Liftmaster #3800 and it only works on sectional doors. So for those looking for a machine that doesn’t mount to the ceiling like a regular machine, the Liftmaster #3800 may be just what you’re looking for, its quiet, has (800 newtons) or the equivalent of 3/4 HP and mounts on both ends of the torsion tube provided you have has at least 10 inches of side clearance, so the idea of ​​this opener is that if you have a space above the garage, it completely eliminates the vibration of a typical opener that hangs below the ceiling, or if you have a low beam in your garage that supports the second floor of your house, or if you have installed attic or storage racks where a typical opener is installed, you can still automate your door using this type of machine.

It can also be used in applications where you just don’t want the opener hanging out in the middle of your garage. I’ve found over the years that the #3800 likes the heavier sectional doors over the lightweight non-insulated models. the advantage of this type of machine is that it will lift sectional doors up to 13 feet without modification, whereas the standard machine will only lift doors up to 7’4″ with a standard track machine, which you will need to get a longer rail to accommodate. extra height such as 8′–9′ or For the 10 foot opening that is increasingly common in newer homes, the Liftmaster #3800 has been a very reliable alternative for us since 2004.

Everyone likes options, but given the fact that there are so many choices when it comes to garage door openers, it also makes it very easy to make the wrong choice for your particular garage door, which can lead to many future service calls and repairs. hopefully this helps clear some things up when it comes to choosing the right machine, and there are a lot of “good” ups and downs with the right system.
