I have just replaced the drive geare and worm gear on my opener Model 41A4315-7 chain drive. After putting it back together and tried to open the garage door it blew the house fuse. I am certin I connected the wires corectly. After I reset the breaker there is no power to the door opener.

I have checked the outlet and there is power to it. Is there a reset button or a way to troubleshoot to see if the opener has power.......Thanks.
