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.

Let me know if it recovers ok?
