Genie chain and belt drive garage door openers flash the red or green LEDs lights next to the Learn button to signal error codes. Follow the troubleshooting in the chart below to resolve the problem causing the error code. For example, when the Genie garage door opener green light blinks 5 times, adjust the chain/belt tension following the instructions in your owner's manual. If the chain/belt tension is okay, you'll likely need to replace the control board assembly.
