The clearest sign of a dying opener in a Las Flores house: the door hesitates, reverses partway through closing, or the wall button does nothing while the remote still half-works. That's the logic board losing its grip on the motor relay before it fails outright. A grinding or clicking from the opener head with no corresponding door movement points to a stripped gear, not the board - different fix, different cost.
If the door reverses the instant it touches the floor, check the sensor alignment first; that's cheap and common in homes this age where the sensors have drifted or picked up dust over the years. If it's doing all three - hesitation, grinding, and reversing - call it in and let us sort which failure came first.
