Garage Door Opener- repair or replace?
The chain recently came off our garage door opener. I was able to get it back on, and in adjusting/tightening to the recommended tension and testing, the chain came off again. It appears that the gear or sprocket on top of the housing is slightly elevated and tilted.
Can this be repaired by an amateur like myself, or do I need to get a professional to repair it?
After calling a few local shops, it sounds like I can buy a whole new unit for less than it will cost for someone to come and look it and possibly fix it.
I greatly appreciate any comments or help!
