Garage door opener shorting out.

As its name sounds a garage door opener is a device used to open or close your garage door from a short distance without getting out of your car. 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. If your sensors or garage door motor is blinking or your door doesn t close it s a sign you could have faulty sensors. This is related to the up limit switch.

Garage door sensors prevent the garage door from closing if there s something in the way. If you garage door is lowering then reversing back to the open position there could. Try making small adjustments. If you don t see smoke you might hear a clicking or humming sound coming from the motor.

The burnt trace s are easy to see. If the wiring connections are okay wait a few minutes before plugging the garage door opener back in disconnecting the power resets the logic board after an electrical disturbance. Then test whether the opener works. If you repair the defect s with a soldering iron and a bit of thin copper wire the opener will be ok.

T his is a pretty uncommon problem but one that can happen after you ve first installed your garage door opener. Sensors are a critical safety feature but can prevent an automatic garage door from working properly. The solder and the copper it is on vaporizes when shorted. If your garage door opener stops working and you see smoke coming from the motor you most likely have a blown starting capacitor.

Garage door openers manufactured after 1993 include sensors to prevent a door from closing on a child or pet. The capacitor is a part inside your opener that stores energy and helps start the motor every time you press the button.
