Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
THe opener seems like it is in a bind or is dragging, making it open roughly sometimes reopening before it completley closes
If you have a Chraftsman/Liftmaster:
1.Check to see if the door is running correctly.
A. Run the door down and pull the emergency release. See if the door will run easily by itself.
1. If it runs hard by hand try lubricating the rollers and hinges with silicone spray or some form of lubricant (not WD 40) And be sure you lubricate the rial and the chain on the operator
2. If the door is heavy and falls back to the ground, you probably have a spring issue (either broken or needs more tension) in this case call a professional door repair company in your area.
B. If the door runs fine then check the up and down force on your operator (the box that hangs from the ceiling). If the light bulb(s) on your operator are on the front and/or back, the force adjustment screw is on the back of the operator. If the lights are on the sides of the operator then the force adjustment screw is on the right side (looking from the back of the operator and facing the garage door). Turn the light blue adjustment screw with the up arrow to a higher number.
C. If this does not solve your problem the top bushing could be going out of your operator. Open the case and see if a lot of black filings are on the top of the big gear. If so the gear assy. will have to be replaced part # 41C4220A
