QUESTIONS & ANSWERS

Ask a Question
  • My door will travel to the set open position and then start to go shorter with each opening, with that it seems to go lower also until it is so low or too much pressure at the floor it will not stay down. I can hear a clicking noise when the door starts to open , at about the first section of the rail , it is a screw drive model. This started about a week or two ago. The unit has been installed for 5 yrs ?? The model no. is 3062, but about 4 1/2 yrs ago the motor was replaced with a factory rebuilt. I can't see a number on it.I spoke with the help line and a optoluctor # 39153rs was thought to be the problem. I looked inside the housing and found that part but would need the trick on how to remove. Thanks for any help you can provide me.
