Sensors are working properly. That is not your problem. The light blinking 5 times is sending the code for RPM sensor or motor overload. Most likely if it is doing this with the door closed it is a bad RPM sensor which is a small printed circuit board just in front of the motor.

Liftmaster 1245 led blinks five time but door will not open


5 flashes of the LED is the code for "RPM sensor or motor overload." You can try unplugging the opener for about 15 minutes to see if it resets itself. Normally if it is the RPM sensor the motor will run for a few seconds and then turn off. Is the door not opening or not closing? Just checking to make sure.

Learn light is blinking in a serise of 4 times.


The light is sending the code for:

Safety reversing sensors slightly misaligned (dim or flashing LED).


Tweak the sensors to make sure they are pointed at one another and both lights are lit and not flickering. If your opener is working okay then you may just need to unplug it for about 5 minutes and it should reset so the blinking light quits.

The led blinking 5 times is the code for "RPM sensor or motor overload." The motor has an thermal switch which opens when the motor get hot from running too much. This automatically resets itself after about 15 minutes. This problem can also be caused when the door opens too far and the trolley jams against the bolt just in front of the motor unit. To correct this you need to loosen the chain enough to eliminate the tension against the trolley and then run the motor until the door closes. While the door is closed locate the 'up limit' control on the side of the motor unit. Turn this control 2 complete turns in the opposite direction of the arrow printed on the cover. Tighten the chain.

The blinking LED is sending the code for "RPM sensor or motor overload. It isn't the motor or it wouldn't run at all. The RPM sensor is a small printed circuit board near the front of the motor. It will be available at Sears or any good door opener service company.

L.E.D lights at back constantly blinking, garage door won't open


If the LED is blinking randomly it is normal. If it is blinking rapidly you have interference from somewhere. To eliminate any interference start unplugging anything electrical and watch the LED. Some things will interfere that you wouldn't even think of like a heater in an aquarium. Check everything especially in the garage.

Craftsman Garage Opener Clicks only and LED blinking 5 times


Just fixed this problem tonight. Had the 5 blink/flash thing. Opened it up and saw that the motor wasn't spinning so it wasn't a bad rpm sensor. Jumped the red to black and then the blue to black to verify motor worked. At that point assumed it was the logic board not telling the motor to start, but I could hear the click of the relay. Pulled the logic board out and noticed a solder joint that had failed directly behind one of the relays. Resoldered that joint and the garage door opener worked again like a dream. Hope that helps someone else.

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.
