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.

My craftman garage opener will not close. The up arrow blinks 3 times and the down arrow blinks 2 times. the button on the unit will not open or close it. It will move about a foot then reverse back.


try holding in the wall button the whole time. if the door closes, then you have an issue with the sensor wiring. if the wall button closes the door while holding in, then post a comment below and we will tell you next steps.

I have a model 139.53672srt1 garage door opener.Door opened fine but will not close from remote or wall switch, light goes on but door does not move or engage.


if you hold down the wall button will the door close? if yes, then the safety photo sensors are the issue==pretty common issue. either they are not aligned or one of the wires to then is lose or broken or shorted out(staples thru the insulation)

I have a craftsman garage door opener model 139.53674SRT2. It was working fine and we opened it and closed it twice today with no problem. The third time we opened it, it would not close. Both led...


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.

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.

Garage Door won't close!


If the main light flashes 10 times when the door reverses it is a problem with the door sensors. Make sure the small light on each sensor is lit and not blinking ever so slightly. If it doesn't flash it is most likely the RPM sensor which is a small printed circuit board just in front of the motor. There is also a possibility that the down force needs to be increased. This is a control on the rear of the motor unit near where all those white wires go. Increase it about a quarter turn.

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.

Garage Door Wont Close Craftsman 1/2 HP (1998)


What it is is the electric beams at the door are getting blinded buy the sun or out of line. They are the two black boxes on both sides of the door about a foot from the ground. Put a piece of card board in front of them not blocking the beam dut to block the sun. All that they are is safety beams for kids so they do not get hurt. If you have to move them to the top where the sun will not hit them. Sorry to say though you can not remove them all the way. Also make sure the lite on them is not blinking if so they are out of line.

Good Luck and Please Rate FixYa!
