If your garage door is not opening properly, your instinct may be the reach for the phone and contact a garage door repair company. This is certainly not a bad idea, but if the issue ends up being something simple, you might end up feeling silly for wasting the repair company's time — and your money! As such, there are a couple of possible little problems to check for before calling for repairs.
Is the Breaker Tripped?
If the garage door simply stopped operating altogether, check to ensure it has not tripped the circuit breaker. Garage door openers do utilize a lot of power, so if you had something else plugged into the same circuit and running at the same time, the breaker may have tripped. Flip the breaker back to on, unplug anything else on that circuit, and try the door. If it keeps tripping the breaker, you probably need to call an electrician rather than a garage door repair company.
Is the Opener Properly Programmed?
If the garage door opens and closes when you push the button, but not when you use the remote control, then you should check whether there is a problem with the remote. First, check that the remote has good batteries. Then, check whether the remote is programmed properly. Its instruction manual should tell you how to program it; follow the instructions closely. If this does not work, the issue might be with the sensor in the opener itself, which is something the garage door repair company should handle.
Is There Something Blocking the Door's Motion Sensor?
There should be a sensor partway down on the door frame that detects whether something is in the door's way, and it prevents the door from closing if there is anything beneath it. Check to ensure there's no debris or grime in this sensor, and wipe it clean. The door might be failing to close because this sensor is incorrectly being triggered.
Is the Adjustment Screw Properly Adjusted?
If the door is hitting the ground and then bouncing back up again, you may just need to tighten the adjustment screw. Use a screwdriver, and turn the screw about 1/4 of a turn. Try opening and closing the door a few times. If it still bounces, turn the screwdriver another 1/4 turn. Keep experimenting until you find the right adjustment.
If none of the fixes above work, at least you tried! You can rely on a residential garage door repair company to solve bigger issues.
