To fix this, open the garage door manually and then use a level to make sure that the sensors are properly aligned. If they are not, then you’ll want to adjust them until they are.

Finally, it’s possible that your Liftmaster garage door opener’s error code 42 is being caused by a faulty sensor. If this is the case, then you’ll need to replace the sensor.
