Thank you for your question Mike.
I am sorry you are having a problem finding the manual for the garage door opener. The number you have submitted did not pull up for me. The model number will be located on the motor unit. To find the model number you will need a ladder to get up to the unit. Once up there, look on both ends for the model number tag. The model number should 139.******. If might be necessary to remove the light lens to see the model number tag. Once you have the model number, please reply below with the number and I will be happy to look up the manual for you.
Thank you for using Manage my life.
