Garage Door Circuit Breaker Details

You can unplug the garage door opener.

Garage door circuit breaker details.

When installing a 240 volt circuit attach the black and red wires into the slots under the screws on the breaker. I ve replaced the drive gears once but otherwise it s been quite reliable. Most modern garage door openers draw from 3 to 5 amps depending on what type of lighting your opener has. 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.

Here are the details. Recently it has started blowing its breaker intermittently. I reset it and the breaker was fine for a few weeks. A lighted garage door opener may not be used to satisfy this requirement even if the light is controlled by its own switch.

2008 nec the not readily accessible exception removed from the code so ceiling receptacles now required to be gfci protected. A short in one of the light sockets could also cause that problem. If your opener has a 200 watt lighting system for example the lights alone will draw just under 2 amps. The breaker tripped again and wouldn t reset.

Try connecting other devices to other power outlets on the same circuit. It s also possible that the circuit breaker fuse or gfci outlet powering the door opener circuit has tripped or burned out. I removed the 100w lightbulb but the trips. The white and bare wires will be attached under the screws on the neutral bus.

My liftmaster garage door opener is 27 years old. I replaced the breaker its a qo 20a thinking it was bad but it kept tripping. You could have a weak circuit breaker or a bad gcfi electrical outlet. If the problem persists ask an electrician to check the breaker.

It s nominally 1 3 hp. But there was an exception for receptacles that are not readily accessible which is defined as above 6 8 above floor such as a ceiling garage door opener receptacle. Exterior lighting detached garages with electricity must have a light outside each grade level egress door and this light must be controlled by a wall switch or motion sensor. A bad drive motor could cause the circuit breaker to trip.

Here are a few reasons your garage door opener might trip your circuit breaker along with suggestions to fix the problem. If you find that other lights or electrical circuits in the garage aren t operating this is the likely cause and you ll need to reset the breaker or gfci or replace the burned out fuse. For 120 volt circuits attach the black wire to the breaker and snap it to the power bus. I think the rate is increasing.

A short in the control board or the wiring of the garage door opener could also cause that problem.
