Any ideas what could be causing my electric garage door stop few inches after I push on the botton to open it. THen I have to keep the botton pushed until door is fully open. Does this mean I need to grease my tracks. Anyone experienced this problem before? What is the solution?

Does the opener have up and down force adjustment screws?

I think it does have an Up and Down force screw.

Try increasing the UP force. (Screw in)

What if it did not have a force adjustment screw? Any ideas there? Thanks
