QUESTIONS & ANSWERS

Ask a Question
  • My model no. 2562 has stopped opening the door. It will raise the door about a foot then will grind away and the threaded drive will stop but the motor will still grind away.

    This sounds like the carriage is possibly stripped out. If the motor is running, but the screw inside the rail is turning, and you hear the grinding noise you would need to replace the carriage. The part number for the 2562 model carriage is 37845R.S. If this is not what is happening please contact Genie customer service at 1-800-354-3643 for assistance.
