I recently installed a GDO blaq on my Chamberlain Whisper Drive unit with a purple button. Everything works fine with the exception of the open/close percentages. Is there a way to ‘reset’ the device and have it recompute how long it takes the door to be open or closed?
Yes, on the device’s internal web page, there’s a button called “Reset door timings” or something like that. Hit that, then use the wall button or remote to fully open and close the door once to re-capture the timing.
