why the genie garage door sensor blinks red

Garage door systems specifically rely on sensor signals, which will transmit closing and opening commands to the motor. In this way, they become the masters of the system’s operation, indicating the positions it should have. Its operation is simple. Starting from the time you press a remote control button, the logic card translates that signal indicating the position to the sensors.

Then, it sends the parameter to the motor to combine with force and take the door to the desired location indicated by the sensor. Suppose it presents problems when carrying out some process. In that case, the sensors will indicate that it is happening with different lights, varying the colour and speed of appreciation depending on the models.

If you have a sensor flashing red light or unusual colours, perform the following steps:

  • Check the Source and Sensor LEDs on the operator; both the red “Source” LED, and the green “Sensor” LED(s) is on and not flashing, the door opener is functioning properly. If one or both LEDs are not on, check the fuse, switch, and connector. If only the red LED sensor light illuminates, disconnect the operator, check for loose wires and reconnect.
  • Check that the “source” and “sensor” LEDs are flashing. If the red “source” LED flashes twice and the “sensor” LED is on. So, check that there are no blocks on the door sensor. Also, make sure nothing is blocking the lightning source. So, if the “Source” light flashes twice and it is the “Sensor” light, check the wiring or call customer service (see “Source” section). If the “Source” light flashes three or four times, check for interference from other electronics or call customer service.
  • Check the “Status” light. If it flashes, try turning the mechanism off for a few seconds. If the problem persists, check that the garage door is in good condition to be opened (i.e., not rusted). Check that the door is not idling and that the forces are set correctly. If the problem persists, check the mechanism or have it checked by an authorized dealer.

  • If you cannot open the garage, check the keyless entry sensor eyes. Make sure it is within range of the garage and that the signal is not blocked. Ensure the keyless entry sensor antenna is in the correct position and that the car faces the garage when pressing the transmitter.
