sears garage door opener - safety mechanism failure
Hi out there!
I've just finished changing the worm and drive gears on a 1995 Sears chain-drive GDO. The chain linkage and the arm that connects the chain to the door had been disconnected before I arrived. I THINK I put everything together properly (I'm a pretty handy fixitman) and figured out the Limits and Force adjustments but the safety-reverse on the door doesn't work properly. It only reverses several seconds after encountering massive resistance.
In addition, while repeatedly testing the unit the capacitory began sizzling and leaking oil! I found that the motor was also quite hot.
Anybody have ideas as to the motor/capacitor problem and as to how to make the safety reverse feature more sensitive?
