New Liftmaster Garage Door Opener Tripping Breaker

A few weeks ago the breaker that my garage door opener and motion light are connected to tripped.

New liftmaster garage door opener tripping breaker.

The wiring in my garage is on the fritz. If the circuit breaker or gfci is tripping repeatedly it s a sign that there is a short circuit somewhere in the system possibly even the garage door opener itself. Only thing on the circuit is the opener and a flourcent light. A short in one of the light sockets could also cause that problem.

I think the op s new garage door opener has a fault tripping the gfi breaker. The garage door at my girlfriends house keeps tripping the breaker. So in here now i manually opened the door.

I d advise a temporary test using an extension cord plugged into a known different circuit to plug in the garage door opener in to for 2 or 3 days and see if the gfi breaker continues to trip after the opener has been removed from the circuit. The breaker tripped again and wouldn t reset. This is a problem that will require you or a service person to replace it. It rained very hard last night and all yesterday the home inspector told her the ground for the garage was not optimal.

I replaced the breaker its a qo 20a thinking it was bad but it kept tripping. A bad drive motor could cause the circuit breaker to trip. A short in the control board or the wiring of the garage door opener could also cause that problem. I reset it and the breaker was fine for a few weeks.

Finally it s possible the garage door opener s motor has burned out and isn t operating at all.
