Why is the Chamberlain PD210 sending eye indicator light not glowing?
- JJanet DuncanAug 12, 2025
If the sending eye indicator light does not glow steadily after installation, it could be due to several reasons. First, ensure there is electric power to the opener. Check for a short in the white or white/black wires, especially at staples or opener connections. Also, verify that the wiring between the sensors and the opener is correct. Finally, inspect for a broken wire. Twist like colored wires together. Insert wires into quick-connect holes: white to white and white/black to black.
