Troubleshooting Guide for Your Garage Door Opener
Has your garage door opener been malfunctioning again?
You may have been in this situation more than once before but if this time, the problem doesn’t go away with your quick fixes, it’s time for some serious troubleshooting. The great news is that certain garage door openers like the LiftMaster garage door opener, Craftsman garage door opener, and Chamberlain garage door opener that were released after 2012, have built-in systems that can help you troubleshoot your garage door issues.
These openers are equipped with Security+ 2.0 and MyQ technology to make the entire troubleshooting process user-friendly. If you’re not sure that your current garage door system has this feature, look at the yellow LEARN button on the back of the housing or sometimes, it’s on the side.
On your LiftMaster garage door opener, Craftsman garage door, or Chamberlain garage door opener, take a look at the back of the motor housing and locate the indicator arrows. There should be two of them – one pointing up and the other pointing down. What you need to do is to count the number of times the up or down arrows blink then look at the guide below to determine the issue. Once you have identified the problem, you will be able to make the necessary repairs.
The Garage Door Does Not Close
Following the instructions looking at the blinking arrows as mentioned above, if you’ve noticed that both the up and down arrows blinked only once, it means that the problem is that the garage door opener is not able to close itself. The lights should be flashing. This means that the safety sensors or what is called the photocells are not correctly installed or not properly connected. It could also be that the wires are cut. To fix this, check the sensor wires and adjust the disconnected wires or reconnect them as necessary, if they are cut.

Here are Other Possible Situations:
- 1 blink up and 6 blinks down means door stops and slides. You have to program the travel module to the correct position.
- 2 blinks up and 1-5 blinks down means there is no sound or movement at all. You must replace the logic board.
- 3 blinks up and 2 down, your settings are not saved. Replace the logic board.
- 3 blinks up and down and the power LED is constantly flashing means there’s a circuit error in your battery backup charging. It needs to be replaced.
- 4 blinks up and 1-4 down, the door stops or reverses which means there are obstructions or you have to reprogram the travel module.
- 4 up and 5 down, you may have to replace the travel module after checking the connections.
- 4 up and 6 down, you need to realign sensor boxes and clear obstructions.
