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

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.
