My centurion garage door is not working correctly. the remotes will not open and close the door, and the door will not operate correcly when the red button onthe control unit is pressed. when it does work, the light clicks on and off for some time. the unit is approx 3 years old, encased in blue plastic cover and operates a sectional door. could not see a model no on the casing

Try to recode the remote opener.

Three blinking lights & door won't close by Candi

Garage door will not open and close with remotes. Three blinking lights occur when we try to close door. What does this mean? It is a Linear unit.

I will assume you mean that your garage door will open with your remote but will not close. It should close if you press and hold the wall control button until the door is fully closed.

If that is the case, the 3 blinking lights indicate that your garage door's infrared safety beams are not properly aligned.

1) Check that the operator has power. The green lights on the sender and receiver should be lit.

2) If the receiver's green light is on, but the red light is off, the receiver has power but is not detecting the infrared beam from the sender. The red light might flash when the beam is partially detected. This can be caused by
mis-alignment or something blocking the beam.

Adjust the safety beam sender and receiver while watching the receiver's red light (stay out of the beam while aligning it). When the red light stays on, the beam is aligned and your garage door should operate normally.

NOTE: If the receiver's red light remains off, check for:

1) Dirt on the receiver's lens,

2) Sunlight shining into the receiver's lens,

3) A short in the safety beam wiring (from staples or at the operator terminals).

No. It's not possible. There is no setup codes to synchronize with.

God bless you

If you Google Centurion D5 moto gate you will find a video listed that shows how to do what you need.

Sounds like your receiver has quit. It is part of the logic board.

Check to see if your child/animal security beam is working correctly. It is an "Electric Eye" mounted about 12 in off of the floor on two mounting points and one side shoots an infra red beam across to a receiver. These points must be reasonably aligned to flash a beam (cannot see) from one point to another. This beam keeps the door open if it is interrupted . If it is not aligned, then the door opener sees a problem and will not close the door electrically. You must aligned the beam by bending the transmitter or receiver untill you can close the door by the remote. Also check to see if something placed in the garage is not blocking the beam first.
