Ask a Question
  • I have a ISD990 Genie Excelerator opener. When the garage is hot in the summer, the motor speed varies greatly. It the temps are normal, it works great. Typically it has the fast up and slow down. With the heat, the down can be extremely fast and the up can vary with a some points barely moving. It never completely stops and always opens or closes. It just runs fast/slow at times it should not. Would this be the motor drive board or circuit board?

    When this happens, is there a green light that flashes on the garage door opener? The status light can help tell what is happening. View more details here, and you can also contact our customer service at 1-800-354-3643 for assistance.

  • Why was the board redesigned? Was there a problem with the previous version?

    No, the replacement circuit board will work with multiple models.

  • If I am replacing a circuit board AND a motor drive board, which should I tackle first?

    Hi Jim -

    Make sure before you begin, unplug the garage door opener, and prior to disconnecting any wires from the back of the unit, you have them marked so you know which ones go back to each screw, after disconnecting those remove the motor cover, and remove one board at a time, it does not matter which one you begin with.  You can replace the Motor Drive board first, then go with the controller board, or vice-versa.

  • I have a model ISD990 Genie Excelrator garage door opener, upon pressing wall mount open button the motor starts the stops quickly it will not repeat unless I unplug the power and plug back in and then it does it again, if I press the light button it will start and stop and start and stop each time I press it is my problem the motor drive board ?

    This could be the control board. Please contact Genie customer service at 1.800.354.3643 for troubleshooting assistance.
