I use my garage door opener almost daily since I park my car inside my garage so I know how important it is to have a good working garage door openers. While you are waiting for your expert answer, I suggest you add to the thread of this question and include the full model number of your appliance so that the expert can provide you with a more detailed answer. I did manage to find a link in where you can enter your model number and your owners manual will pop up in where you can find some good troubleshooting tips. I hope my link is useful.

Thank you for your question.

I can understand your concern when the door opener stops working.

You say it is loosing power and you also state that the power is good.

First I would ask you, have you check the condition of the outlet that the door opener is plugged into?

I would suggest that you get a ladder and step up to the plug in the ceiling and activate the work light and then wiggle the power in the out to see if it stays on.

If it stays on then we have to consider that the motor unit have an issue.

When you say it is loosing power are you referring to when it operates the door stops when you activate the door. Or is it stopping and reversing?

If it stops in either the up or down motion of the door I would suggest increasing the force adjustment by one number in which ever direction it is loosing power in.

On the motor head there are both travel and force adjustments. If you refer to your owner’s manual it will illustrate those locations and the adjustment procedure.

If you could provide a little more detail as to what is happening I will be happy to help you.

Thank you for using Manage My Life.
