If your sensors are not pointed at one another the light on one of them will go out. Tweak them a bit. If you cannot get the light to come on then your sensors are bad.

Pl refer user manual. In general flashing light may mean : no water flow, salt chamber empty, door not closed etc. It all depends on the error code message designed.assigned by the manufacturer.

It sounds like your door sensors may be misaligned. If when you try to close the door the main light flashes 10 times and the door reverses to the open position this is the case. Make sure the small light on each sensor is lit and not flickering. Tweak the sensors to see if you can get both lights to come on. If not you have a bad sensor.

Motor hums,but it does not close. Light works and


Is the trolley jammed against the bolt just in front of the motor unit? If so remove the bolt and then run the door until it is closed. Now locate the 'up limit' control on the side of the motor unit and turn it 2 full turns in the opposite direction of the arrow printed on the cover. Remember to replace the bolt.

If this isn't the case you could have a bad start capacitor.

Motor humms but door doesn't go up or down!


5 flashes is the code for "RPM sensor board or motor overload." If your door is stuck in the open position the trolley may be jammed against a bolt just in front of the motor unit. Remove the bolt and run the opener until the door is closed. Now locate the 'up limit' control on the side of the motor unit and turn it a couple turns in the opposite direction of the arrow printed on the cover. Be sure to replace the bolt.

I think the trolley has jammed against the bolt just in front of the motor unit. Remove the bolt and then run the door until it is closed. With the door closed locate the 'up limit' control on the side of the motor unit. Turn this 2 turns in the opposite direction of the arrow printed on the cover. Replace the bolt.

The door does not respond when using the remote inside the car


If the main light flashes 10 times when the door reverses it is a door sensor problem. Look at the LED just to the left of all those white wires and see if it is flashing a code. It will flash a number of times and then pause if it is sending a code. If the code is 5 then you have a bad RPM sensor board which is just in front of the motor. Also try increasing the down force just a bit. This control is on the rear of the motor unit.
