Garage door opener motor rubber bushing


Answer 1 I am not a garage door opener technician, only a user for many years. The following answer is based on my experience, and hopefully will be replaced or improved by a professional. Many garage door opener manufacturers, in order to make their product SAFER, have added a circuit in the motor, which measures the amount and changes in the operating electrical current. The purpose of this is to detect anything blocking the movement of the door [e.g., a child, a person, a pet, a vehicle, etc.] Even "dragging" bearings/bushing INSIDE the motor can cause this. Upon detection, the door is supposed to stop, and, sometimes, even return to its previous stopped position [usually full open]. ANYTHING, which causes the door motor to "work harder," can trick that detector and cause the situation you describe. If there is nothing blocking the door, I have found that "dragging" rollers, or bearings/bushings inside the motor,can cause the problem. If this is the cause in your case, then...

Top 5 Garage Door Openers Comparison

Important Things You Should Know

In simple words, the door openers are motor powered devices that are designed to open and close the garage door. They can be operated manually or by remote controls and they are the best option when it comes to securing the garage. All the openers function by using a specific driving system and there are three types of such systems: chain drives, belt drives, and screw drives. The first ones use a metal chain to lift the door and they are the most common type on the market. However, the disadvantage of these systems is that they can be very noisy in comparison with the other types. The belt drives are operated by belts, which are more flexible and therefore they operate smoothly every time the door is opened or closed. They are a great option in case your garage is placed under a bedroom. The last type, namely the screw drives, operate along a steel rod mechanism, but they can also be noisy...

A residential garage door opener. The motor is in the box on the upper-right.

A garage door opener is a motorized device that opens and closes garage doors. Most are controlled by switches on the garage wall, as well as by remote controls carried by the owner.

The electric opener[edit]

The electric overhead garage door opener was invented by C.G. Johnson in 1926 in Hartford City, Indiana.[1] Electric Garage Door openers did not become popular until Era Meter Company of Chicago offered one after World War II where the overhead garage door could be opened via a key pad located on a post at the end of the driveway or a switch inside the garage.[2]

As in an elevator, the electric motor does not provide most of the power to move a heavy garage door. Instead, most of door's weight is offset by the counterbalance springs attached to the door. (Even manually operated garage doors have counterbalances; otherwise they would be too heavy for a person to open or...

Best Garage Door Openers

Why Buy a Garage Door Opener?

We’ve been reviewing the best garage door openers for more than half a decade. This year we chose the Chamberlain Premium as our top pick. It’s an efficient, reliable garage door opener, and it comes with a backup battery system that works in a power outage. This model also has a preinstalled timer that closes your garage door automatically so you don't have to worry about whether you left the garage door open.

Our value pick is the Chamberlain PD76EV. It costs about $50 less than our top pick, but it has most of the higher-priced model’s advantages. The PD76EV has the same lift capacity, horsepower, lift system and automation compatibility. However, it doesn’t come with advanced features such as a backup power source, close timer and keyless entry pad. If you can live without those, this opener is a great choice.

The warranties on garage door openers tend to be quite generous. In fact, it’s normal...

Those who have experienced the convenience that an automatic garage door offers will likely never go back to a manually opening door. Especially in bad weather, there’s no better feeling than a simple click of the button keeping you and your belongings dry. That being said, that same storm might bring with it power outages that could leave your garage door incapacitated and you stuck out in the cold. On the flip side, when you’re inside the garage with no power and you need to get out for work it’s important to understand these tips on how to open a garage door manually.

Trip the Trigger

Virtually all garage door openers have a bypass switch for situations such as when the power goes out, a motor goes awry, or the remote opener dies. On most garage door openers there is a rope with a handle on the end (usually red). This manual release handle disengages the trolley from the attachment point to the rail. Pulling on this rope will put the garage into manual mode so if...

Feel free to wire it up wherever you like, but I chose to go with the hi-beam on mine. You want to find something that has a 12v switched circuit to tap into.

If you go to the hi-beam on the lite, you will need to determine where you want to tap into the circuit. On my Harley Fatboy Lo, the wires run directly from the switch on the handlebar through the forks, right into the headlight enclosure. I found the best place to tap in, was right in the housing, directly behind the light enclosure. I took out the headlight enclosure and accessed the wires the same way you would if you were changing the bulb.

Next you will need to determine which wires you need to tap into. I have an H4 bulb, so the two outside contacts provided me the "common" wire and the "hi-beam" wire. Figure out what kind of bulb you have and head to Google for some help with the wiring diagrams for your particular bulb type.

Using the wire tap-ins, splice the black wire from the project box into...

When it comes to Garage Doors there are three main types of garage door openers: Chain Drives, Screw Drives, and Belt Drives. Many times customers will inquire regarding our point of view on which one works the best. Well, the fact is that they will all function a bit differently. It is surely up to you to choose which one will work out the best for you. We’ll advise you on all the features of each type and let you determine.

Chain drives use a metal chain to run the door on its track. Chain drives are the most frequent used drive, and they are generally less costly … However they are usually the loudest. If you have a detached garage away from the house (Where the noise does not matter), a chain drive is possibly the best fit for you. If you want to hear when the garage door is being opened or closed, so for example you will have an idea on what time your children are getting in throughout the day, then this could possibly be a good fit for you. Chain drives require...

If the garage door opens correctly but fails to close completely, there may be one of three common causes:

1. The close-limit switch may need adjusting. Your garage door has set-limit switches that instruct the motor when to stop running—both when it is opening, and when it is closing. If the close-limit switch is set wrong, it may prevent the door from closing It can also cause the opener to reverse or pull back up when you attempt to close it.

The close-limit switch is a safety measure that... keeps people from being hit and having the door close on them—it is a necessary and required device for all garage door openers. Adjusting the limit switch will stop your garage door from behaving erratically.

Different garage doors have different means of adjusting the set-limit switches, but it is usually a screw feature on the motor unit that is turned to adjust how far the door descends.

2. The safety sensors may need adjustment or realignment. Near the...

In most Chamberlain, Liftmaster, and Sears openers a motor turns the worm gear and drive shaft inside the opener, which rotates the sprocket attatched to the top of the drive shaft. This turns the chain and moves the door.

The most common issue that occurs is when the ridges in the gear wear out because the gear lubrication has evaporated. As a result of the worn gear, the sprocket cannot turn the chain and the door will not open nor close.

This tutorial demonstrates how to replace the gear and sprocket assembly on all Chamberlain, Liftmaster, and Sears openers.

1. Unplug the opener.

2. Remove the bolt that secures the chain to the trolley by using two 1/2 " open end wrenches or two adjustable wrenches to loosen the nuts.

3. Screw the second nut back on the bolt.

4. If the sprocket is still on the top of the opener, carefully remove the chain from the sprocket. Keep your fingers on the sides of the chain at least three inches away...
