Storage Door Openers – Reviewed
Class is now in session….
There are various kinds of storage door openers on the market, so which one is best for you?? The very first thing you need to notice, is that storage door openers should not a one dimension matches all software. Storage door openers are made to operate higher if its on the suitable kind of door, most of our repairs are achieved on machines which are both put in improper or the opener is on the improper kind of door, and in a number of instances only a low high quality opener.
Now thus far I’ve used the phrases “opener” and “machine” each have the identical which means, they discuss with the whole mechanized operation so after I say “opener” I am not referring to the hand held machine in your automobile.. .that is known as a “distant management” or simply “distant”. With that being stated there are a number of kinds of storage door openers available on the market.. there are screw-drives, there are chain-drives there are belt-drives and final however not least direct-drives generally known as “Jackshafts”. However lets take them one by one and begin with…
These machines have been well-liked (not essentially good) on all kinds of doorways for the higher a part of 45 years however…due to their design they do require common upkeep. Again within the late 6Os,7Os and early 8Os, Genie used a really sturdy metal within the “carriage” or “trolley” and the machines have been robust! Even with out grease on the screw they might run for what appeared like ceaselessly then they switched to a lighter grade metal and all that went downhill, the openers would nonetheless go so long as any on the market offered you usually greased the screw however who ever does that !! So the typical lifetime of the Genie screw-drive trolley was about 4-5 years and that is being beneficiant, Liftmaster or Chamberlain or Craftsman,all made by the identical mfg…(Chamberlain) additionally has a screw-drive and it has the identical downside so to counter that they use a plastic inside trolley and a self lubricating housing across the screw to maintain the warmth and put on down, however the self lubricating housing actually solely lasts a few 12 months..or the equal of your guarantee then its again to the identical ol, identical ol,”grease-grease-grease”. My official opinion on screw-drives is…avoid them, they’re previous know-how with a brand new look to them.
Any such machine has been round for so long as screwdrives give or take 5yrs and so they have come alongside method. Chain-drives have all the time been very sturdy machines however caught a little bit of a nasty rap when Sears began promoting a do-it-yourself mannequin from Chamberlain known as the Craftsman, now this machine, though known as a “chain-drive” was pushed by a sequence on one aspect and a cable on the opposite and it appeared like nothing could possibly be achieved to make this factor quiet as a result of the cable would stretch till it broke on the loop. So from then on the chain-drives began getting a nasty rap as a “coffee-grinder” or noisy machine, though it wasn’t a real chain-drive.
The Liftmaster 1300 sequence of chain-drives…greenback for greenback are pretty much as good a machine as you may get, they’re versatile, in that they will deal with any kind of door from heavy wooden to gentle metal, one-piece or sectional and they’re highly effective and cheap and comparatively talking…low upkeep, however to get so far they’ve had many good enhancements alongside the way in which. Chamberlain has added a sequence spreader which retains the chain from slapping the rail, swapped the entrance sprocket to a pulley drastically decreasing chain noise, they switched out the metal worm gear to a nylon worm gear contained in the case to scale back warmth on the helical gear and so they eliminated the 2 stress springs off the inside trolley to scale back door bounce and its a strong one piece rail with a full wrap round chain.
The parts on this machine can deal with what the motor places out, so normally you do not want a 1/2 hp to raise the door, and so far as routine upkeep goes..there’s nearly none, simply have the 2 nylon gears contained in the motor case lubricated each 7 yrs and that is about it, within the uncommon case the place you occur to personal a home proper on the seashore and solely use the opener in the summertime then you’ll be able to spray the chain with silicone to maintain the hyperlinks on the chain free. The 2 fashions I favor which were actual work horses for us during the last twenty years are presently known as #1346=1/3 hp and #1356=1/2 hp.
A number of producers make belt-drives as of late however I like to stay with essentially the most dependable model which to me is Liftmaster, we feature most manufacturers however favor to cope with the model with the least quantity of issues so lets concentrate on Liftmaster belt-drives for now. Remember the fact that belt-drive openers are a VERY door particular machine, they do NOT work on 1pc doorways very properly or for very lengthy and will NOT be put in on a 1pc door. To maintain it easy there are two kinds of belt-drives…AC and DC.
The AC mannequin belt-drive referred to as a method I, is without doubt one of the early mannequin belt-drive designs and primarily its a chain-drive motorhead that is driving a belt as an alternative of chain. It’s minutely quieter than a chain-drive minus the facility and to me… not machine, however a simple one to promote as a result of its cheaper than a DC mannequin and most of the people does not know the distinction, they simply know belt-drives are speculated to be high of the road and this can be a belt-drive, so they’re none the wiser to the methods, sellers should buy these kind of machines less expensive than their DC motor counterparts and promote them for the belt- drive (premium) value. What makes a “DC motor” belt-drive quiet is the motor! In any other case why would they even provide it in DC, plus the opposite profit is having the ability to have a battery back-up connected so it is going to run even with the facility turned off.
In its easiest kind a DC motor places out extra torque than an AC motor and the horsepower for DC is rated in “Newtons” quite than HP however the DC motors even have a “sluggish begin/sluggish cease” function which helps maintain the whole operation quiet. When an AC motor machine is activated it goes O-60 or ought to I say “O to full velocity” in a single shot…the second you push the button, however the door however just isn’t on the identical web page and needs to withstand the sudden power and that is the place a number of the noise comes from..principally its the jerky-ness of the door resisting the opener, the place because the sluggish begin of the DC machines act as a smoother motivator for the door to get it going with out all of the jerky-ness, and it does the identical because it involves a cease, so for the primary two inches and on the final two inches it slows down, tremendously decreasing the clanky-ness of the whole operation.
The DC machines additionally electronically calibrate the strain wanted to function a door based mostly on its resistance and weight,
which leaves little room for installer error, in different phrases the installer can not set the machine to crush your automobile hood or your cat, AC motors are on the mercy of the installer, if he units the power adjustment too excessive, it crushes, if he units it too low the door will bounce again up on a chilly or moist morning when you are fortunately driving off to work not figuring out your storage door shall be open all day and that model spankin’ new Craftsman software field you simply received on your birthday is about to be bought for a fraction of the worth its value on the native swap meet….all since you thought you bought a belt-drive storage door opener for a cut price value!! Closing ideas…AC motor belt-drives= not good (higher off with a chain-drive) DC motor belt-drives=Superb, very quiet, however very door particular. (Solely works on a sectional door)

This part is straightforward as a result of there’s actually just one accessible and its a Liftmaster #3800, and it’ll solely work on sectional doorways. So for these of you on the lookout for a machine that doesn’t mount to the ceiling like a standard machine does, the Liftmaster #3800 may simply be what you are on the lookout for, its quiet, has (800 Newtons) or the equal of three/ 4 hp and mounts on both finish of the torsion tube offered you’ve got atleast 10 inches of aspect clearance, so the thought behind this opener is that if in case you have a room above the storage, it utterly removes… the vibration of a typical opener that hangs off the ceiling, or if in case you have a low beam within the storage that helps the second story of your home or have had a loft or storage shelving put in the place a typical opener could be mounted you possibly can nonetheless automate your door utilizing the sort of machine.
It can be used on purposes the place you simply merely don’t desire an opener hanging down in the course of your storage.I’ve discovered over time that the #3800 likes the heavier sectional doorways vs the sunshine non-insulated fashions, one other good thing about the sort of machine is that it’ll raise a sectional door as much as 13 toes excessive with no modifications whereas a standard machine solely lifts doorways as much as 7’4″ with a standard railed machine you would want to get an extended rail to accommodate the added peak of say an 8′–9′ or 10 ft excessive opening which is changing into extra widespread in newer homes.The Liftmaster #3800 has been a really dependable different for us since 2004.
All people loves selections, however given the truth that on the subject of storage door openers there actually are so many selections that it additionally makes it very straightforward to make the improper selection on your specific storage door which may result in many future service calls and repairs so hopefully this may clear up a couple of issues for you on the subject of selecting the right machine and you’ll have many “good” ups and downs with the suitable system.
