Jammed/FROZEN Chamberlain LiftMaster garage door enclosed position repair and cleaning FULL video

My Chamberlain 1/3 horsepower LiftMaster professional garage door opener was stuck in the closed position with the garage door carriage jammed closed causing slack in the chain and Boeing of the rod. The garage door would hum and click briefly when you press the button but continued to force it closed even more jeopardizing breaking the sprocket for the motor. This video goes through my diagnostics and fumbling around to be honest trying to figure out what is going on but it does end with a perfect operational and freshly cleaned system with zero squeaks! This is my wife's side of the garage so she's going to be very happy about that :-) I use poking and jabbing levity in the video but don't be offended or just move on to someone else's video. any comment by a Karen is just going to be deleted anyway with no mental real estate gained for you. If you're a professional then you shouldn't even be watching this so just move on. I'm a DIY everything homeowner from automotive both gasoline and diesel motor building and modifications, Yamaha Waverunner customization and repair/refurbishment, slide in truck bed camper remodeler, want to be garage electrician, generator installer and anything else I can get my hands on. I'm retired, I have time, and almost zero patients so some project get a little frustrating and might end up being a little bit comical at times. enjoy
