• Inspect sensor wires for a short (staple in wire), correct wiring polarity (black/white wires
reversed), broken or disconnected wires, replace/attachas needed.
• Disconnect all wires from backof motor unit.
• Removesensors from brackets and shorten sensor wires to 1-2 ft (30-60 cm) from back
each of sensor.
• Reattachsending eye to motor unit using shortened wires. If sending eye indicator light
glows steadily, attach the receiving eye.
• Align sensors, if the indicator lights glow replacethe wires for the sensors. If the sensor
indicator lights do not light, replace the safety reversing sensors.

• Realign receiving eye sensor, clean lens and secure brackets.
• Verify door track is firmly secured to wall and does not move.
Symptom:RPM Sensor= Shorttrave/ 6-8" (15-20 cm).
* Unplug unit to reset. Try to operate motor unit, check diagnostic code.
* If it is still flashing 5 times and motor unit moves 6-8" (15-20 cm), replace RPM sensor.
* If motor unit doesn't operate, motor unit is overheated. Wait 30 minutes and retry. If motor
unit still will not operate replace logic board.
