Talk:Garage door opener

This article only discusses the transmitter & reciever. It needs to cover the actual door opening mechanism and safety interlocks as well.--Hooperbloob 07:34, 31 July 2005 (UTC)

Safety devices
Door opener systems are required to have at least two safety devices that will assist in preventing the door from shutting on an obstruction (a car, a box, a pet, a person, etc.). Originally door opener manufacturers incorporated pressure sensing circuitry that compared the normal operating Cheese burger forces working against the opener to any changes in the force required to open or close the door and would stop or reverse the door when the force required to move the door exceeded the threshold level. The amount of pressure (force) to open and close the door, and the associated adjustments thereof are commonly referred to the "open force" and close force". There are threshold limits for these forces that are commonly in the neighborhood of 10 pounds of pressure. Thus, it is very important to properly maintain a door so that the door opener does not have to exert an overt amount of force to either open or close a door. As technology advanced there arose a need and the capability to incorporate an additional safety device commonly referred to as safety sensors. Typically the sensors operate by sending an infrared beam across the opening, within five inches of the ground, from one sensor, "the sending eye" to a sensor located on the opposite side of the doorway know as the "receiving eye". When the door is in motion and something breaks the invisible beam across the doorway, the door will reverse to the open position if travelling down and will stop if the door is travelling up. This type of system has been required since 1992 in all residential door opener systems to prevent doors from striking objects in the downward motion and hooking onto objects in the upward motion. An additional feature of this safety sensor system is to turn the lights on on the door opener if something breaks the invisible beam. —Preceding unsigned comment added by 65.151.156.151 (talk • contribs) 14:54, 6 April 2006

too OR to go into the article but
i discovered that my door opener will in fact open the door despite the spring having broken and the opener having to provide the entire muscle power. i wouldn't count on it in every case, of course. Gzuckier (talk) 02:36, 4 October 2009 (UTC)
 * This article doesn't mention springs, but Garage door does. It's a little vague, leaving out a significant description of the most common type used for solid doors, extension springs, and instead focuses on the types used for sectional types. Unfortunately., most sources of information are commercial companies and their advice may be skewed by their commercial interests.   Will Beback    talk    02:49, 4 October 2009 (UTC)

How to Maintain A Garage Door

As long as our garage doors operate as they should we do not give them a second thought. With a little care and maintenance we can keep them in tip top shape. Besides that who wants to open their garage door by hand on a cold rainy day.

Step 2 Keep your door hardware clean and lubricated and you will prevent most problems.

Step 3 Clean all the oil buildup and grease from the door tracks. A buildup can cause the roller wheel to jump out of track or bind up.

Step 4 Relubricate the clean tracks with light oil or graphite. You can also use lithium grease. Open and close the door to spread the lubrication around the track.

Step 5 Lightly oil the hinge pins on the door. Oil the roller wheels and make sure they are in alignment with the track. Most roller wheels can be adjusted a little.

Step 6 Use only graphite do no use oil or grease on the lock set. Oil and grease can collect dirt and make it hard to use after a while.

Step 7 Make sure the bottom of the garage door is clean and in good shape. Replace the seal if needed or paint if wood.

Step 8 Tighten all screws nuts and bolts on the door.

Step 9 Lubricate the chain drive or the screw drive in the colder months with lithium grease so it doesn't drip on your vehicle. Wipe down the extra grease with a rag and you are ready to go. —Preceding unsigned comment added by 76.31.199.185 (talk) 22:14, 19 October 2009 (UTC)

"Our RF Remote Control Tri-State DIP Switch Calculator" section -- should it be removed?
The calculator section looks like it was copied from somewhere else. It mentions "our" Remote Control Tri-State DIP Switch Calculator but leads to a separate site. Should it be kept, revised, or removed?

 * Good catch. It does appear to be commercially driven content.    Will Beback    talk    06:58, 4 June 2011 (UTC)

Forgotten Dimensions - Replacement Door Opening Mechanism may be too long
There is a MISSING DIMENSION, not listed on any retail box, nor any web page or product review (on Amazon, Lowes, Home Depot). This becomes critical for garages with a structural beam or other member occupying the same place as the garage door motor/chain/belt assembly. If other contributors or OEM could provide a chart of lengths of various models, it would be very useful information to post here.

Example: An original eight foot garage door opener assembly hangs from a 9x16 structural beam that spans the width of garage. Replacing the opener with a popular 9-10 foot rail assembly turns out to be impossible without risking head injury and collision with roof and window of a minivan.

If 10+ feet of "backroom" (unobstructed place along ceiling measured from top of closed garage door back into the garage) then the popular motor assemblies in the US as of 2011 can likely replace shorter one without incident.

It is critical that before buying / installing a replacement to FIRST DETERMINE that your installation has enough backroom in which to install the replacement.

(This does not apply to wall mounted motors available for torsion spring sectional or roll up doors.) — Preceding unsigned comment added by 75.7.228.97 (talk) 00:38, 30 October 2011 (UTC)

Possible new RF frequency in used starting in 2011
I found the flowing at http://www.homelink.com/faqs

The HomeLink Repeater Kit is designed to allow compatibility between a newer Chamberlain, Sears Craftsman, or LiftMaster garage door opener fitted with a yellow antenna wire and the HomeLink system in your vehicle. These garage door openers were manufactured in 2011 or later. If your opener does not have a yellow antenna wire or is not one of the brands listed above, please consider purchasing a Universal Receiver to ensure compatibility

May be a different RF frequency is being used. If so, this should be reflected in Wikipedia. Mikedz (talk) 23:59, 22 April 2012 (UTC)

door opener and other wikipedias
I have just removed the wikilink to de.wiki as it was about the concept of the "garage door". FYI if you create the more generic page door opener, you can connect it to Ouvre-porte--Alexmar983 (talk) 00:26, 25 December 2013 (UTC)

Adoption Within Consumer Market of Homeowners
The article lacks definition on this point. Yes, radio transmitters were available for bomb detonation during WWII, but the widespread application of transistors and micro-circuitry (which was not widely available until after circa 1960) made remote (from the automobile) garage door opening a rarity until the mid-1960s.

It would be useful to run down the names of initial manufacturers and trace their early production/sales numbers. — Preceding unsigned comment added by Homebuilding (talk • contribs) 18:23, 19 December 2017 (UTC)

When invented and by whom
This article needs to state when the garage door remote was invented and what the men's names were who invented it 2601:204:0:2610:A088:118A:9AF9:ED0 (talk) 16:57, 22 October 2021 (UTC)
