Garage Door Sensors are safety devices that prevent the door from closing to people, pets or objects in the door. The sensors are situated above the ground at every side of the doorway opening and create a low-voltage beam which completes the electric circuit once the door is triggered. Garage Door can display a variety of symptoms once the sensors need attention. In most cases, it’s possible to troubleshoot the system and fix the cause of problems. Before beginning, be sure that the electrical cable in the opener is plugged in and the electric circuit is busy. A garage door sensor that is functioning erratically or not at all is a hazard that you can know solve Albuquerque garage door repair immediately.

Cleaning and Adjustment
1- Remove any debris, dust or cobwebs in the electric-eye lenses on each sensor using a clean rag. Cycle the Garage Door throughout the opening and closing actions using the controller in the garage or the remote unit by a car or truck. If the door does not close entirely without hesitation, proceed with adjusting the sensors.
2- Loosen the small nuts which hold every sensor into the L-brackets using a small adjustable wrench. Loosen the nuts just enough so that the senors stay facing each other and may be transferred by hand.
3- Adjust every sensor in small increment by hand before the red or green power-indicator lights on every are illuminated. This indicates the electrical eyes have been aligned and the circuit is intact.
4- If it does not close completely and with no hesitation, proceed to another section to troubleshoot the electric circuit.
1- Raise the Garage Door using the control button on the garage wall or the remote controller device from a car or truck. Inspect every sensor to be sure that the red or green power-indicator lights are illuminated. Proceed to the next step if both lights aren’t illuminated.
2- Stand a stepladder in the region of the Garage Door opener component. Unplug the power cable from the socket at the ceiling. Remove the cover on the back of the device. Identify the link terminals at which the ends of this low-voltage Sensor wires attach. Reattach a loose cable to the appropriate terminal. Plug in the power cable and observe the lights onto the sensors. If both lights aren’t illuminated, visit another step.
3- Inspect the double-strand insulated low-voltage wires from each sensor into the back of the Garage Door opener. Use the stepladder to inspect the wires close to the upper portion of a wall and also in the ceiling. If no damage is noticed, both sensors must be replaced. Proceed to the following steps if some wires are bare, burnt or burnt into a couple of places.
4- Loosen the terminal screws which join the faulty wires in the back of the overhead device. Start at the ceiling and then pull the wires from the insulated fasteners in the ceiling, walls and along the side of the doorway opening into the sensor. Disconnect the ends of these wires from the terminals over the Sensor.
5- Determine the length of a replacement cable using the faulty cable. Cut a bit of fresh double-strand insulated low-voltage cable to length with electric pliers. Strip 1/2 inch of insulation off equally strands at the same end.
6- Start just above the Sensor. Hold the opposite end of the cable through the fasteners in the side of the doorway, the walls and also, the ceiling. Strip the ends of these wires as before. Connect the wires to the appropriate terminals and tighten screws. Plug in the power cable into the opener device.
Things You Need
§ Clean Rag
§ Small adjustable wrench
§ Small screwdriver
§ Electrical pliers
§ Double-strand insulated low-voltage wire (optional)
Contact a professional if troubleshooting or cable replacement does not fix problems with the door closing properly.
Don’t operate on electric or low-voltage circuits unless the power cord is unplugged or the appropriate breaker is switched off in the electrical panel.
