The Chamberlain, Liftmaster & Craftsman garage door
openers have a built-in diagnostic indicator that will
assist you in troubleshooting your garage door opener.
There is a LED light next to or near the smart button (programming learn button) on the outside of the motor cover up above the antenna. On the garage door opener pictured below the LED light is between the square purple smart button and the purple antenna wire. The LED functions as a diagnostic indicator by slowly flashing a failure code continually every eight seconds until the fault is corrected, the garage door opener is reset, or the necessary parts are replaced.
Observe the flashing LED & count how many flashes occur in a row between pauses. Then refer to the chart below for the cause of your garage door opener not working properly. Once you have fixed the problem the opener will reset itself for most issues. However note below on the last two failure codes it does require that you manually reset the opener by unplugging the unit. If you still can not get the opener functioning properly after following the steps below you should contact a local garage door dealer for a service request to resolve the problem.
