If your garage door opener’s motor has burned out, you’ll likely need to replace the entire opener. However, there are a few things you can check before you replace the opener. First, unplug the opener and plug it back in to see if that resolves the problem. If not, try manually opening and closing the door to see if the motor is able to move the door. If the door is stuck or the motor makes strange noises, it’s likely that the motor has burned out and will need to be replaced.
