No power, not sure what’s causing it garage door opener 

First and foremost go and check your panel that is located outside your house or sometimes in your garage see if the circuit breaker has been triggered and if that’s not the problem go into or look around your house or in your garage my problem was in the garage so I had to look for a GFCI breaker switch that had been triggered to the last power to the garage opener at first all the GFCI switches are normal and then I found one that my water softener in my freezer were hooked up to my water softener power was not on so I figured that’s the GFCI that I need to fix fix that problem and went back to the socket and it was working fine.
