Question about Chamberlain Powerdrive PD422D 1/2 HP Security Plus Screw Drive Garage Door Opener
If you have a Chraftsman/Liftmaster:
Check to see if the door is running correctly.
Run the door down and pull the emergency release. See if the door will run easily by itself.
If it runs hard by hand try lubricating the rollers and hinges with silicone spray or some form of lubricant (not WD 40)
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 (or down) arrow to a higher number.
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

Tips for a great answer:
WHEN HOLDING IT DOWN MAKES THE DOOR CLOSE PROPERLY THE PROBLEM IS IN THE SAFETY EYES.
ARE BOTH LEDS ON? - CHECK FOR A LOOSE OR BROKEN WIRE.
ARE THE EYES WIRED CORRECTLY?
ARE THEY AIMED AT EACH HOLDING DOWN THE WALL BUTTON OVERRIDES THE SAFETY EYES.
