Customer Question

My 1/2 hp chamberlain garage door will not close. It gives the ten flashes for an obstructed door. Error code on the unit is 4 up arrow flashes then 6 down arrow flashed signaling misaligned sensors. I have moved the two sensors 1 ft apart with bright green LED on one and bright orange on the other.

Hi John,

Check that the wiring from the sensors is not damaged or disconnected.

Restart the system.
