Reversal is a safety behavior. Causes include the sensors, the floor, the force setting, or a door that has become too heavy. Do not defeat the sensors.
In short. Reversal is a safety behavior. Causes include the sensors, the floor, the force setting, or a door that has become too heavy. Do not defeat the sensors.
A door that starts down and comes back up is doing what a modern opener is built to do when it thinks something is wrong. The photo eyes may be misaligned or blocked. The door may be hitting an uneven floor. The spring may be so weak that the motor hits its force limit. Those are different fixes.
Taping a sensor, raising the force until the door crushes a test object, or disconnecting the eyes is how people get hurt. We will not describe those adjustments. Call and describe the symptom: reverses at the floor, reverses halfway, or will not move at all.
The opener may be the symptom and the cable may be the failure. Diagnosis is the opener service.
