Reversing sensor blinking

The only thing that will cause the main light to flash 10 times and the door to reverse to the open position is a sensor problem. Make sure the light on each sensor is on and not flickering ever so slightly. Make sure they are not moving when the door starts to close. Lights on sensors should not blink. One light should stay on constantly and the other sensors light should go off when you block the sensors.

I agree with the closing resistance may be set incorrectly, all openers have a safety feature that senses if something is keeping the door from closing, this is back force, you set the sensitivity at the back of the opener motor control, it is a little dial, reduce the setting just enough to stop the door from kicking back open when it closes, I had this very same problem with my craftsman and this adjustment fixed it.

You most likely have a bad wall control or the wiring to it. An easy way to check this is to remove the connection at terminal #1 on the rear of the motor unit. Just remember that your wall control will not work with this wire off. Your remotes will still work though.

If the main light flashes 10 times when the door reverses it is a door sensor problem. Make sure the sensors are pointed at one another and the small light on each sensor is lit and not flickering. If you cannot get both lights on you have bad sensors.

Check to make sure the door sensors are pointed at one another and the small light on each one is lit and not flickering. If you cannot get both lights to come on then your sensors have failed.

If the main light is flashing 10 times when the door reverses when closing it is a door sensor problem. You can override this with the door control but not with a remote. Make sure the door sensors are pointed at one another and the small light on each one is on and not flickering.

It sounds like you have a problem with your wall button. I would remove the button from the wall and then disconnect the 2 wires on the back. Remember where they go as they are color coded. You can then momentarily touch the two wires together to check the operation. There isn't enough voltage there to bother you.

One thing to remember. If when the door reverses the main light flashes 10 times it is a door sensor problem and nothing else.

Anytime the main light flashes 10 times and the door reverses to the open position it is a door sensor problem or the wiring to them. Nothing else causes this symptom.

If the main light blinks 10 times when the door reverses it is a sensor problem. Sometimes the sensors are misaligned just enough that the light comes on but closing will be intermittent. If the main light is not blinking 10 times and you have increased the down force it might be a bad RPM sensor board. This is a small printed circuit board just in front of the motor. I might add I have never seen one intermittent but there is always a first time.

sounds like the safety door sensors are at fault,also did you reprogram the remotes by pressing the smart button on the logic board,when the safety sensors are bad the door will reverse to open state.you can pully the rip cord to manualy close the door untill you solve the problem.
