Liftmaster Garage Door Opener Beeping Every 30 Seconds

If your Liftmaster garage door opener is beeping every 30 seconds, there are a few possible causes. One possibility is that the batteries in the remote control are low.

To fix this, you will need to adjust the sensors so that they are aligned with each other. Finally, it is also possible that there is a problem with the circuit board in the garage door opener. If this is the case, you will need to contact a qualified technician to have it repaired or replaced.
