If you detect a small bend you may be able to straighten it out yourself but anything more extensive will require professional intervention.
My garage door trolley is stuck.
Surprisingly your garage door just being locked can be causing your problem.
The garage door opener motor will hum when attempting to open or close the door but is unable to travel due to being lodged against the bolt tab.
Over time your garage door track can be damaged resulting in a garage door that gets stuck open.
Even with regular maintenance garage doors can sometimes stick refusing to open or close.
Typically this is caused by a mis adjustment.
Weather damage and harsh impacts can also distort your garage door track.
