Check the opening first
Remove obvious objects and debris from the doorway and sensor path. Do not defeat the sensor system to make the door close.
Watch where the reversal happens
A reversal immediately after movement can mean something different from a reversal just before the floor. The timing helps narrow the cause.
Mechanical binding can trigger reversal
Tracks, rollers, hinges and door balance can create resistance that the opener interprets as a reason to stop or reverse.
