To troubleshoot a Genie garage door opener, check if the Sensor, Status and Source lights are on without blinking to ensure that the door mechanism is working properly. Additionally, check if there is power supply to the keypad and that there is no loose connection in the control panel wiring.
If the red Source and green Sensor lights of the Genie garage door opener are turned off, check the plugs, fuses and breakers. If only the Source light is off, check the wiring.
If the red light blinks twice and the green light is steady, check if something is obstructing the beam's source. If the green light is off and the red light blinks twice, check the wiring. If the red light blinks three or four times, it implies that some electronic item is interfering with the beam.
If the Status light blinks, unplug the unit for several seconds. Also, verify that the garage door's force settings are correctly set, the unit is not rusted and it is not in vacation lock mode. Further, ensure that the keypad contains the correct code and the unit's wiring, fuses and breakers are intact. If the keyless sensor is not opening the garage door, position the antenna and car properly.
If the garage door light does not switch off, check for any loose or faulty connection in the indoor control panel. If problems with the garage door opener persist, call a technician.
