Help ,My motorized garage door opener is tripping my breaker when I use it , can I install a higher amp breaker ?
First thing to do is check out the door. Unplug the motor and pull the disconnect cord to separate the door from the drive mech. Now manually try opening and closing the door. If it doesn't move smoothly (or worse, you just now notice a broken spring or cable), then fix the mechanicals. Only after that should you start suspecting a bad breaker, and as EdBeal commented, never increase the rating.
