Craftman door opener 139.53962SRT
Great forum. I have two questions about my craftman 139.53962SRT garage door openers. I'll post the second one in a seperate note.
I have a two bay garage with two openers.
On one of my doors, when using the remote or the fixed button in the garge, the door will go down about 1-2 feet and then automatically reverse to the fully open position. Once returned to the open position the two light bulbs on the side of the motor will click on and off for a period of time. If I hold the fixed button inside the garage down the door will fully close but if I let go the door retreats back to the fully open position and the lights blink.
I disconnected the door from the track and it moves freely up and down. When closing manually half way down the door will the allow gravity to take over a close by itself. The spring looks good.
I have no idea what is going on but at least once today it worked fine.
