What should I do when the Genie garage door blinks red?

The following are some quick, simple steps on what you should do when the Genie garage is flashing red light or other abnormal colors:

The first step is to check the operator's red "Source" LEDs and the green "Sensor" LEDs. If one or both of these LED lights are not on or flashing, check the switch, fuse, and connector. If only the red LED sensor light blinks, disconnect the operator and check for loose wires.

If the red "source" LED blinks twice. Check for anything blocking the light door sensor, check for loose wiring, and call customer service.

If the "Status" light flashes, try turning the operator off for a few seconds. If the issue persists, check for rusting or any other condition that may affect the normal functioning of the garage door.

How to Fix a Blinking Garage Door Sensor

Blinking garage door sensors can be very annoying, but they are not a cause for concern. There are a few common problems that may result in a malfunctioning sensor. First, make sure the sensors are connected properly. If they’re not, then you will need to replace the safety reversing sensors and the wiring. You should also make sure that the light in the sensor is steady, and that the wires are not damaged or shorted. Other possible causes of a blinking garage door sensor include the following:

When the sensors start to blink, it may be a short or a broken wire. Check the white and black wires to ensure they’re not twisted or misaligned. If the lights continue to blink, then the sensor is out of alignment. If this happens, then you will have to replace the receiver and the motor circuit. If you’re still seeing blinks, then you should contact a garage door technician to repair the problem.

Another cause of blinking garage door sensors is misalignment. If the sensors are lining up correctly, the beam will not be interrupted. A faulty sensor may also be causing the garage door to close improperly. If the sensors are aligned properly, you can prevent the problem by cleaning them. If the problem persists, it’s best to replace the safety-reversing sensors.

How Do I Reset My Genie Garage Door Sensor?

Your Genie garage door opener’s infrared sensor should blink twice before the door opens. You can reset the sensor by pressing the program key or up/down key on the device for five seconds. After the LED lights go off, the entire device should go dark. If the lights are still flashing, the error code you entered on the unit has been cleared and the system is ready to work.

First, you have to find the “program set” button on the unit. Then, press and hold it for 3 seconds. A purple or circle-shaped lead will illuminate. Then, press and hold the button again. If the sensor is blinking red, it is most likely because of a malfunction in the sensor bracket. If the issue persists, tighten the bracket. Then, try the next step: replace the battery.

The green light means the sensors are on. If the green light is blinking, it’s a good idea to replace the battery. The red light is a warning that the sensors are off. If they’re off, the door won’t close or open. If the LEDs blink fast, you’re probably in need of a replacement sensor. You can reset the sensor and your Genie garage door opener will work perfectly again.
