Sears garage door operator won't close the door. Here are some details:
- double wide metal door, no insulation so it is fairly light
- both torsion springs just professionally replaced (one had broken, not sure if problem existed before this change, it isn't my door)
- door operates easily when disconnected from opener
- Sears chain operated opener, maybe 10 years old
- door opens without problem with the opener
- when closing the door with opener it stops and reverses almost at the beginning of the cycle, that is, within 6"-12" of top
- if the wall button is held continuously the door will close completely
- this problem does not occur early morning or early evening (the weekday times the opener is operated) temperature problem?
- I tried to adjust the down force control on the opener but it had no effect
Any ideas about what the problem might be or what to look for?
