#UP AND DOWN ARROWS BLINKING ON GARAGE DOOR OPENER CODE#

Now, try to operate your garage door once more. Make sure that all the wires are connected properly and securely to their appropriate terminals. The black and white wires should be connected to the black (colour may vary with each brand). The white wires should be twisted together, and should be connected to the white terminal. ItвЂ™s also worth checking the safety eyesвЂ™ wire connections to the motor unit, as the wire may be loose. If the sensor is getting power on and off, the connection point may be faulty and the sensor will need to be replaced, not the wire. If the wires are hidden away behind walls and crevices, you will need to repair or replace any broken or damaged wires by running a new wire externally anyway. Bear in mind that it may be extremely challenging to trace a faulty wire.

If the error code indicates a problem with the wiring, check the wiring and look for any damage or separations in the wires. 4 up blinks, 6 down blinks: this means that your sensors are temporarily obstructed or misaligned.1 up blink, 4 down blinks: this means that you have an obstructed or misaligned sensor.1 up blink, 2 down blinks: this means that the sensor wires have shorted or are reversed.1 up blink, 1 down blink: this means that the sensors are not installed or their wires are broken in some way.On the other hand, if you have a newer Liftmaster, Chamberlain or Craftsman garage door opener with вЂњup and downвЂќ arrows (or yellow learn button), they will blink in these orders to indicate the following errors: 4 blinks if the sensor eyes are slightly misaligned.2 blinks if the sensor wires have shorted.1 blink if the sensor wires are disconnected.For a Liftmaster, Chamberlain or Craftsman garage door opener: if it is a single LED light, it will flash: Look for an error code from the blinking LED light on your motor unit. If one (or both) of these lights not coming on, even after you have tried to align them, in order to diagnose the problem further, youвЂ™ll need to check the openerвЂ™s LED troubleshooting light which is located on your garage door motor unit.

If it closes smoothly, your problem was simply misaligned garage door openerвЂ™s safety eyes. Now try closing the garage door as normal. If the yellow or orange LED light reappears and stay solid, you have successfully realigned the sensors. If the green or red LED light (receiving) is off, carefully adjust the safety eyes until the light reappears and stay solid. Check that both these lights are on, assuming there are no objects blocking the path between them. The sending sensorвЂ™s yellow or orange LED light should always be visible, whereas the receiving sensorвЂ™s green or red light should only be visible when the sensors are aligned, unobstructed and function correctly.

This вЂњsendingвЂќ sensor transmits infrared light to the вЂњreceivingвЂќ sensor, which has a green or red light on it. The вЂњsendingвЂќ sensor has a yellow, orange LED light on it. Nothing blocking the sensors? Check their alignment and error codesД®ach sensor has an indicating light. Remove any items and see if the door now works as normal. A small object such as a stray bucket, childвЂ™s toy or paint can be enough to block your sensorsвЂ™ infrared beam and triggering the garage door opener safety feature. Now without further ado, here are three steps for troubleshooting faulty safety eyes: 1. They could also just simply be defective. Flashing openersвЂ™ light bulbs most likely signify that the safety sensors are blocked, out of alignment, or may have problems with the wiring. Most garage door openersвЂ™ light bulb will flash and/or their self-diagnostic LED lights will communicate an error code when an issue like this occurs. The sensors are designed to detect the presence of a car or object (and not squash it), but defective sensors could cause a garage door not to close, as the garage door opener programmed to do so if it вЂњbelievesвЂќ that something is blocking its path. Garage door sensors utilize infrared beam of light to detect the presence of objects, a similar technology to that found in remote controls and burglar alarm systems. If neither of them works, itвЂ™s more than likely that youвЂ™re looking at faulty garage door opener which its sensors (or safety eyes) are being obstructed, misaligned, or not connected properly. If the garage door system has been thoroughly inspected and the mechanics are not damaged, try to operate the garage door with both remote control and wall console. Here are the most common garage door problems or breakdowns, that will cause a malfunctioning door to not close: Are you having troubles with a garage door which simply will not close? Garage doors comprised many moving parts and a single faulty component can prevent your garage door from closing.
