Raynor 1245rgd navigator learn button blinks

Blinks 5 times, then 5 more. After a short pause it starts again. When the burtton is pushed the door moves about a foot. If it is pressed a second time, it returns that foot. Just replaced the worm gear and sprocket. Did I do something else?

The code it is flashing is "RPM sensor or motor overload." It is not a door sensor problem. The RPM sensor is a small circuit board just in front of the motor.

I have the raynor 1245RGD 1/3 HP. Garage Door Opener. The light in the garage used to turn on when I opened the door to the garage. Now it doesn't. I also don't know how to change the time on the clock.


Unplug the opener and remove the bulb. Use a small screwdriver to pry out on the center contact in the light socket. Replace the bulb and plug in the opener.

My garage door opens fine but will not close unless I press down the button on the wall. The sensor lights are solid and I unplugged it for a minute and I'm still having the same problem.


If your main light flashes 10 times and the door reverses to the open position when you use your remote it is a door sensor problem. It is sometimes very hard to see if one of the sensor lights is flickering.

If the main light does not flash then you can try increasing the down force just a little. This control is on the rear of the motor unit near where all those white wires go.

Check the small LED near the smart/learn button. If it is flashing a code of 5 blinks then a pause and 5 blinks it is the RPM sensor. This is a small printed circuit board just in front of the motor.

The LED flashing 5 times is the code for "RPM sensor or motor overload". Usually if it is the RPM sensor - which is a small printed circuit board just in front of the motor - it will run a few inches and then reverse. I doubt very much it is the motor. I would pull the logic board and check for loose or missing traces on the printed circuit. Especially if you have had any electrical storms or power surges.

Craftsmen garage door won't open. 5 blinks and a pause on ind.


Most commonly this is caused by the trolley jamming against a bolt just in front of the motor unit. Remove the bolt and run the opener until the door closes. On the side of the motor unit you will find a control labeled 'up limit'. Turn this about 3 turns in the opposite direction of the arrow printed on the cover. Be sure to replace the bolt. Should do it for you.

Blinking on learning indicator...push the remote or wall button nothing works...what happen?


If that LED is blinking a code let me know what it is. For instance 5 blinks and a pause then repeats. If it is just blinking randomly that is normal.

Motor moves 5 in" and reverses and light blinks 5 times


In the manual it says if you can hold the wall button down & door closes. You have a short in the wiring to the reciever eye. Try substituting some new bell wire in its place, or test the wires for continuity.

Craftsman Garage Opener Clicks only and LED blinking 5 times


first off, hitting extra button on remote would not do anything. Is door up or down/ where is trolley that attaches to chain, by door or motor. Is is jamned against a bolt. Try a paper clip and jump from white to read terminal. Does it work. Does light bulb blink 10 times. I ignore the diagnostic lights and go by symptons. Give more info.
