What is the most common cause of garage door opener error codes?

Whether there’s an obstruction or they’re misaligned, the most common error codes pertain to the safety sensors . They’re positioned low to the ground and can easily collect dust and debris or become misaligned after being bumped into.

How do I know when the error blink pattern ends?

To help you identify where the error codes begin and end, there’s a substantial pause between sequences. The pattern will begin, followed by a few-second pause, then begin again.

How do I reset the error code after I’ve addressed the issue?

Once you or a professional has fixed the issue, you can typically reset the error code by unplugging the opener, waiting around 30 seconds, then plugging it back in. Some codes can also be reset by pressing the Learn or Reset button. Your owner’s manual will have specific instructions for your model.
