IChmberlain Garage door does not pen or close


The light flashing 5 times is the code for "RPM sensor or motor overload" and the 10 clicks sounds like the relay for the main light bulb that flashes when the door sensors are blocked or misaligned.

I have a Chamberlain garage door opener, Series CG40, 1/2 HP, #41A5021-1F. It opens just fine using the opener located on the wall. However, when I try to use the remote it does not work. I have installed...


Try programming this way. Hold the button down on your remote and then press and immediately release the smart/learn button. If this doesn't do it your remote may be bad. The wall control is hard wired and doesn't use the receiver that your remote does.

Chamberlain remote has stopped working, new


WHEN YOU CHANGE THE BATTERY NO NEED TO REPROGRAM THE REMOTE.
THE FLASHING LIGHT TELLS YOU IT IS SENDING A SIGNAL THAT IS BEING RECIEVED IT IS JUST NOT THE CORRECT CODE TO OPEN THE DOOR.
REPROGRAMING THE REMOTE SHOULD SOLVE THE PROBLEM

My garage door opener doesnt close all the way.


The motor is probably either stalling because the door is too stiff, or you have a beam break detector that is being triggered when the door is halfway down.

Beeping light coming from unit


Unplug the unit for two mins. and plug it back in. That should stop the blinking & beeping, but blinking & beeping mean a problem. What kind of operator do you have? Maybe I can help you troubleshoot the problem.

Chamberlain door will not close, despite down force set to max


Problem solved, sort of-
My unit has self diagnostic capabilities: next to the remote sync red button, is a yellow light the indicates diagnostic readings by blinking. In my case the light was flashing 5 times after the door failed to close. This meant RPM sensor failure. I rechecked the sensor and "flywheel" cap and found that it was not completely secured. With the "flywheel" in the proper position, providing readings for the RPM sensor, the door completely closed.
But my yellow diagnostic light is still flashing 5 times. My door is operating correctly, but the diagnostic feedback is still not completely happy with my RPM sensor. So I will keep and eye on it.
