Tip & How-To about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

How to lubricate/safety check your garage door.

This garage door tip should be done 1-2 times per year, depending on the type of lubrication used, and the amount of use the door in question gets used in a given time. A good silicone is the best lubricant to use. Liquid wrench makes a very good, economically priced spray type that can be found at most hardware stores. Spray the lubricant on the hinges, there will probably be 9-25 of these hinges depending on the height and width of your door, and may be made of steel, aluminum or plastic material. There will be ones on the outer edge of the door and the middle of the door, possibly in more than one place in the middle. Then lubricate the rollers that the hinges rest on, some call these wheels. Also lubricate the track, horizontal and verticle tracks. If you have the kind of spring that is above the door on a rod when it is closed then lubricate this as well as the pulleys on the sides of this shaft that the cables wrap around. If you have the kind of springs that stretch out as the door closes then lubricate the 4 pulleys the cable snakes through as well. Disconnect the door from the opener and raise it. It should raise and lower with 2 fingers easily. It should stay all the way up, down and rest in the middle. This will keep your garage door running at peak performance. Repeat next year or as needed. If your door starts squeeking it is time to do it again.

Clean the chain rail with a solvent that can remove old lubricant. Re lube with Lithium based lubricant that does not "harden" when the temperature drops - other types of lubricant tend to "harden" with lower temperature that strains the movement of the door. Clean excessive lubricant from the rail as it can drip onto your vehicle.

my centurion garage door is not working correctly. the remotes will not open and close the door, and the door will not operate correcly when the red button onthe control unit is pressed. when it does work, the light clicks on and off for some time. the unit is approx 3 years old, encased in blue plastic cover and operates a sectional door. could not see a model no on the casing

Centurion Systems: (you will have to C&P the full URL shown below)

There are only two systems of door opener, XTrac and RDO.

Manuals can be found here: (Page down until you see the appropriate section.)

Note that the driven shaft requires periodic lubrication.
Although most systems should be lubricated with Molybedenium disulphide grease (applied manually), I find that a small amount of spray oil every 6 months works wonders.
The shafts can and do aquire dust, and this can cause the load on the drive mechanism to exceed limits. If lubrication does not solve the problem, then you may well have a drive unit failure, requiring repairs by the manufacturer.
Note that NO lubricant should be applied to the steel door guides.

How/where do you lube a 10 year old 1/2 HP Chamberlain garage door opener to make it run quieter?

First thing you need to do is determine if it is the opener or the door that is making all that noise. The door is usually the culprit and you can lubricate the roller bearings and each pivot point of the door with silicone spray. Do not use grease and do not lubricate the channels that the rollers roll in. Some WD40 on the springs will help them live longer. The only place to lubricate the opener is the rail if it is a chain drive. Use lubri-plate on it. The screw of a Chamberlain screw drive opener does not require lubricant.

my Lift Master Formula 1 is not closing all the time. It will close about 1~2 feet the reverse and reopen. This happens using the remote and the manual button. Also, after it reopens the light blinks several times (about 5 or 6 times...). It is only 5 years old and has worked fine until the last 4 weeks, the problem is intermittent, the rail are greased but not with too much grease, the belt following the ceiling is fine and the garage door is even in the open and closed position.... Can you help? Thanks, Roy.

I recommend this to everyone with garage door opener problems:

Use the pull cord and disconnect the opener from the door. Operate the opener and let the carrier slide back away from the door. Is the carrier moving smoothly when disconnected? Next, lift the door by hand from the bottom to the top. Is it moving smoothly? If not, lubricate the hubs of all the rollers on both sides of the door. Check the cable pulleys at the top sides of the door channel, lubricate them as well. Are all cables in all the pulleys, there are 4.

what type of oil I use

The Remington manual for model 111409-01 states: "This Pole Saw requires lubrication only to prevent rust on the guide bar and saw chain. The saw chain provided is pre-lubricated at the factory. With each use of the Pole Saw apply a small amount of lubricating oil directly to the saw chain (see Figure 8). The oil will distribute itself around the chain and guide bar groove during use?preventing rust. We recommend using SAE #30 motor oil for lubrication and rust prevention."
