garage door works sometimes
I have a problem with my 10 year old stanley garage door opener. It stopped working a few days ago. When I try to open or close the garage door, I just hear a humming from the motor and the light flashes. It almost seems as though there is resistance from the garage door. HOwever, if I pull on the release arm, I can open and close the garage door manually fairly easily. Also, if I turn on the garage door opener, the chain moves back and forth now. If I reconnect the release arm, the garage door now opens and closes as usual. However, if I can come back in about 10-15 minutes, the garage door does not open again. Do I just have a bad motor that needs to be replaced? I already tried playing with open/closer force adjustments and don't seem to work.
