Make sure your stable door opener is unplugged. This step insures that no one unintentionally attempts to open or close the stable door while you are working on it or you do not accidentally inaugurate the door while servicing it.

Step #2
Disconnect the door from the outer trolley by manually pulling the red disconnect rope and manually close the stable door.

Caution
The stable door Must be in the fully done position during all repairs and inspection.

Assuring that your stable door is done will reassure that your door will not fall or make any movement that would cause injury or startle you. We advise that once the door is done that you clamp the door down using a vise grip or clamp above one of the rollers to prevent the door from being opened from the outside.

Step #3

Step #4
Remove the sprocket or belt pulley retainer cap. Commonly this has a clip on the back if you press in it will release.

I all the time advise marking the position of the chain or belt to the sprocket prior to removing. This can categorically be done with white out, tape or any other means. This step helps assure that your chain or belt gets reinstalled in the definite position and makes for quick and easy reference if needed later. Take off the chain or belt from the sprocket and then slide the inner trolley to the done position until it engages the outer trolley. Place loose chain/belt on the end of the rail closest to the sprocket. I typically duct tape the chain to prevent it from falling to the floor and getting all twisted and dirty.

Step #6
It is now time to Take off both end covers and the main housing. The end cover are each attached by three or four ¼" head screws that can be removed with a ¼" nut driver or socket. Be sure to unplug the wire to the circuit board.

Step #7
Remove the retaining clip and the drive gear for the limits. Also at this time Take off the limit switch assembly by squeezing the sides just below the bracket by the drive gears. There is no need to disconnect the wires as it is ok to leave this limit assembly hang by the wires. Do not make any adjustments to the limit assembly screws, this will insure that there is minimal adjustment needed to the limits after you perfect your repair and run your stable door opener.

Step #10
Remove the four 5/16" hex head screw's that hold the motor assembly to the frame of the stable door opener. Be sure to put your hand under the motor before removing the last screw to prevent the motor from falling. Slide the motor assembly off the drive shaft and place in a safe place. (Not on top of the ladder for sure reasons).

Step #11
Remove the three hex head screws holding the sprocket assembly to the main chassis using a 5/16" nut driver or socket. Now it is time to decree if you want to replace the main gear only or the whole sprocket or all chain drive models 1984 to present.

Step #12
Skip this step if you are replacing the whole gear and sprocket or pulley assembly. If you are going to replace the drive gear sustain the driveshaft on a block of wood and drive the lower roll pin/Tension pin out with a 5/32" punch. See photo example below.

Step #13
Remove and replace the worm gear. In most cases it is not significant to replace the worm gear unless it shows signs of wear. If you wish to replace this gear Take off the shaft collar with a 1/8" hex wrench. Please be sure to note the location of each of these components as you disassemble so you can re-install in permissible order. When you receive your gear kit, you will find there are parts not used in your model this is because these kits are universal and work with many models of Sears, Craftsman, Wayne Dalton, scholar Mechanic, Liftmaster, True Value and other brands of stable doors openers. Only replace the parts that are used on your stable door opener. Take off the 3 nuts that hold the motor to the frame and then Take off the worm gear. Install the new worm gear production sure the roll pin is properly seated in the new gear. Re-install other components in reverse order. After you perfect this assembly I advise you lube the worm gear so you do not forget.

Step #14
Begin reassembly in reverse order. Be sure to fully lube the main drive gear and that grease is on each and every tooth. Attach the gear and sprocket or pulley assembly to the main chassis with the three 5/16" head screws. Install the assembled motor frame to the chassis with the four 5/16" head screws and reattach the red, blue and white wires; now Install the limit assembly and the limit drive gear production sure they mesh properly. You can now Install the Rpm sensor and reconnect wires. Install the metal cover and end panels, be sure to plug in the circuit board and reconnect photo eye and push button wires.

Step #15
Reconnect the power cord to the opener and cycle the opener until the sprocket completes a perfect clockwise cycle. The trolley must be in the fully down position before installing the chain. Now you can Take off the tape from the rail and reinstall the chain. The chain and sprocket reference mark should be close to lining up. Tighten the chain so that the chain is ½" above the base of the rail at average for "T" style rails and ¼" for square tube rails. Get the chain tightening lock nut.

Warning
Note when adjusting and testing your stable door motor it is foremost
to make sure no one is in the path of the intelligent door.

Caution
It is foremost to know when testing your stable door opener it is potential to over cycle the motor
and have the motor temporarily overheat and stop operating.
To prevent this try and not control the door opener more than 10 cycles
without giving it 5-10 minutes to cool off

Step #16
Now run the opener and test to see if the door opens to the definite position and closes to the definite position. If you need to make adjustments use the travel adjustments screws to make fine adjustments. I advise only production diminutive adjustments ¼ turn or less at a time. For reference one full turn of the screw equals approx 2" of travel on ½ and ¼ Hp models and 3" on ¾ Hp models.

Step #17
Once you have your doors travel adjustment definite it is time to adjust the force. This is the pressure that it takes to assure your door opener will control safely. The first step in this process is to check the down force. With the door open naturally inaugurate the stable door opener and when the door reaches the half way point grasp the door from the bottom and try and stop it. If the door is hard to stop or does not stop decrease the down force adjustment in small increments until it reverse upon inexpensive force. If the door does not close and the light begins to blink growth the down force adjustment in small increments until you can check the reversal at half way. Adjusting the force does not warrant that your operator will reverse on 1-1/2" object at the floor. For more information on adjusting the reversal at the floor see your owner's hand-operated or call the manufacturer.

garage Door Brackets: To Replace or Repair?

There are at least 7 different brackets that work to hold your carport door and occasion components in place. General maintenance involves checking the screws for tightness, although you should always avoid over-tightening. Other repairs may need the help of a professional.

You might not realize how heavy the door is, because you can raise it manually with relative ease. This is something of an illusion. The doors are easily very heavy. It is the torsion springs at the top of each door that allows it to be raised without a lot of exertion.

Door Bottom

As you are leaving or arrival home for the day, take the time to watch the panels rise. Are they tantalizing smoothly and quietly or is there are lot of shaking and noise?

Noisiness or shaking could indicate that a bracket is cracked or loose. If the issue is not addressed in a timely manner, the results could be bad. A section could fall on your vehicle. The weight of the door could cause other components to break or pull loose. If you don't spend a microscopic time and money now to check for the cause of your problem, you could spend a lot of money in the future, repairing the damage.

Although the styles and designs vary from one manufacturer to the next, there are some similarities. You should consideration a 5 inch bearing bracket in the center of the door. This one is under a great deal of tension. You should not try to replace it on your own. You can tighten it, if it seems loose. But, if it is cracked or does not tighten as it should, you should call a repairman and have it replaced.

On the top inside corners of each side is another pair of brackets. These work loose relatively easily and are normally easy to tighten. You can replace a cracked one as long as you have good tools.

Another pair is placed at the bottom. A singular one is referred to as a "lift lowest bracket". They are more complicated than some of the others. They include a Milford pin and a cable holding stud.

With low headroom doors, there are additional brackets and carriers. Most are long-lasting as they are made of metal with a galvanized steel finish, but they can come to be damaged, just like any other piece of hardware.

I recently read an narrative where a homeowner was advised by an laborer in a home improvement store to turn a cracked bracket upside down and drill a new screw hole. That is not something I would ever recommend. If your fix fails suddenly, you will end up spending a lot more in the long run. So, replacing is always good than repairing.

Home improvement market sometimes sell singular carport door brackets. If you need to replace one, you may as well replace the other. It has received just as much wear and tear as the other. It might look alright for now, but it won't last for long.

How To Replace The Rollers On Your Patio Door

Have you noticed your patio door is getting harder and harder to open? Maybe it's time to convert the rollers on the door. They commonly last from ten to fifteen years but they do wear out and its a job that a do-it-yourselfer can perform with a tiny advice and some strong arms to get the door out!

Sliding patio doors are ordinarily aluminum but there are many wooden and vinyl models on the market. All of them use ball bearing rollers to slide indeed back and forth. The aluminum and some vinyl doors have a door bottom that is held in place by 2 screws on either side of the door near the bottom. Under the screw is ordinarily an open hole in which there is an adjusting screw to raise the roller up and down. The wooden doors often have pairs of rollers due to their extra weight. The adjusting screws are accesible straight through plastic caps exterior holes in the front of the door bottom.

Door Bottom

I mention the adjusting screws because you need to check them before choosing to pull the door out and replace the rollers. Slide a big flat blade screwdriver underneath the door on one side and lift slightly to take off the weight from the roller. Use an additional one screwdriver to turn the adjustment screw. See if that makes the door slide better.

Sometimes thats all thats principal but if the adjusting screws wont turn or are totally missing, you will have to lift the door out of its track and take off the large screws keeping the door bottom on and pull the door bottom off. Get help to lift the door out. Two habitancy are needed to safely handle even the smaller patio doors. The door bottom may not pull off indeed especially if the door is old. Check for any metal tabs that may be keeping it on and gently work the bottom off.

Some old aluminum and vinyl patio doors have rollers that use one screw both to mount the roller and to adjust it. These types of rollers can often be changed without removing the bottom of the door. Look considered at the bottom of the door in case there is room to pull the roller assembly out.

Wooden patio door rollers are somewhat easier to change, although the door itself is much heavier. The rollers are often screwed in to the wood door bottom. take off the screws, and out come the roller.

Some Vinyl patio doors are glued together. They were never intended to come apart. You may not be able to take off the rollers if you see no descriptive screws keeping the frame together. Also vinyl doors are often fragile with age and crack indeed as you try to pry off the door bottom. Take extra care if you have a vinyl patio door.

Once you have the bottom off the patio door it should be easy to see how the rollers are held in. Usually, removing one screw or bending a metal tab is all thats necessary. take off the rollers and take them with you to your local glass shop to get the proper replacements.

To reassemble all things start by adjusting the new rollers so they are up as high as they can go. You dont want them getting in the way when you reinstall the door on its track. Make sure you cover the roller retaining screws with cork or rubber if they come near the bare glass in the door bottom. If the metal screws touch the glass, it will crack.

Replace the door bottom, reinstall the screws that obtain it and lift the door back in to place. Succeed the instructions gave earlier for adjusting the rollers. You should now be able to see the door move up and down when you turn the adjusting screws. You will also be able to align the door with the frame using the screws. Your patio door lock may need to be adjusted to compensate for the new door height.

Try the door and you should be amazed at how easy it is to close. It should only wish a incorporate of pounds of force to open and close. No more fighting with a heavy door and you did it all yourself!
