Having a garage door opener has become so regular, that I seldom see a garage door with no. However, because it is a mechanical device, and if improperly set up, together with a 400 pounds garage door (give or take some), it is going to hurt you badly! There’s a well known phrase – “if it works, do not touch it” (or fix it) – but maybe there ought to be yet another one added to it “if it had been correctly installed”…
The majority of us hate instructions but stay with me until the end of the article – it might be helpful for you, particularly if your garage door opener has been installed by somebody else, it’s obsolete, or you are not sure if what you did with it is really safe.
There are several different types of garage door openers and this isn’t a review of them.
This is all about safety futures that lots of people (homeowners / contractors) neglect to put in properly.universal garage door opener.
Additionally, it recommends, that any garage door openers with no such safety future should be replaced. External entrapment protection system refers to:
An electric eye – 2 photoelectric detectors installed on both sides of the garage door monitor – they should not be installed higher than six inches from the garage floor (4″-6″ is the recommended location). Such setup ensures that a small child can’t crawl beneath the detector’s invisible beam. If the light beam is broken during the door closure procedure, the door should reverse and stop. If there’s anything around the sensor light beam path or both sensors are out of alignment, you will still be able to close the door by holding the wall button correct the problem rather than forcing the doorway to close. I’ve seen numerous garages utilized as storage in which it’s not possible to see the lower part of the garage door from the place the push button has been installed, so you might not understand what’s blocking the light beam. Believe it or not but I often see two sensors taped together and secured over the garage door opener … or installed really high on both sides of the garage overhead doors opening. Remember – security sensors have to be installed in 6″ in the garage floor to prevent modest children from crawling beneath the light beam – using them around the ceiling is merely requesting a accident to happen.
When it detects pressure exerted by any obstruction, then it should stop and undo the doorway.
The garage door opener undo on obstruction future must be set correctly. If this is the only security future (no door edge sensor or photoelectric eye) – it will become critical. It’s also crucial in situations where an electrical eye has been improperly mounted (too high or in a different location – such as on the images above). Make sure, that you’re adjusting the proper pair of screws, cause most versions of garage door openers may also have “up / down travel” alterations – read the label. The rule of thumb is to put a 2″x4″ block of wood underneath the door and attempt to close it. The garage door opener / upward force must be corrected in this way, when the door bottom edge touches the obstruction, it will instantly reverse. Some recommend using paper towels rolls instead of a wooden cube, because it’s a density similar to the human body and particularly tiny kids. If it’s possible to get the garage door opener sensitivity adjustment that near, it might be perfect!
Up – Down travel is also quite important because of it, often combined with an improperly adjusted Up – Down force, might damage the garage door opener and the doorway.
Down travel ought to be corrected so whenever the door it’s in a closed place – the base weather strip is slightly compressed (not crushed completely).
Up travel – if the door is fully open, the garage door opener arm mount shouldn’t ever hit the opener or a protective bracket / twist – in the maximum, it should stop right before it, without really hitting it.
The garage door opener is not a crane – it’s a system that replaces your hand at opening / closing process. This means is that until the opener arm is physically connected to the doorway, you need to be sure the door spring tension has been correctly adjusted and the door is just as balanced. If you want to check the doorway already equipped with an opener, disconnect the opener arm only when the door is fully closed – be cautious, cause a door spring tension may be too large and it could pull up the door when the opener has been disconnected.
When springs are appropriately adjusted, you should be able to easily lift / lower and halt the garage door in any elevation, and it ought to remain at this level with no help – stay clear of the doorway route and do not put your fingers between the door sections when doing any tests. In case the doorway is out of balance – does not behave like explained above – telephone the professional to correct it this is a really dangerous procedure if you don’t understand what you are doing!
Any time you install the garage door opener, make certain the upper door panel or door section (with single panel doors) has been bolstered – that applies to one and double garage doors. Reinforcement bar does not usually come with the door, it’s an additional piece of metal you need to pay for. To get a single door, without the electrical opener, it isn’t absolutely crucial. For a double door, I’d highly advocated one bar along the top, at least one more along the bottom border, for heavy doors the next one may be required, and installed with or without the opener. Wide doors with no reinforcing bar begin sagging after a while, and will likely crack at the middle of the top panel, directly above the garage door opener arm attachment area.
Garage door opener push – recommended installation is at about 60″ to prevent small children from playing it, and in a location where you can see the overhead door when shutting.
