Question about Home Security
I have a 3/4 HP 315 MHz Garage Door Opener (model# 139.53990DS). The opener will not operate via any remote or wall switch. The LED is lit on the wall switch and on the safety sensors. When the wall switch is pressed, you can hear a single click at the motor that sounds like an electrical switch, but the motor does not run at all. No sound comes from the motor. The Diagnostic LED blinks 5 times. I have reset the motor by unplugging and plugging it back in. It did not help.

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.

with the door down, disconnect with the emergency release, see if the motor operates
with no load...if the the track moves you probably have something obstructing the door
ie; a broken spring, door locks, etc ... the chain should be adjusted for just a little
**** mid way down the rail (1/4") if it still doesn't move ... call sears.

The trolley (the part that moves back and forth and is connected to your door) of your opener is most likely jammed against the bolt just in front of the motor unit. You can remove the bolt or loosen the chain until your unit will run. Once the door is closed find the 'up limit' on the side of the motor unit and turn it about 3 turns in the opposite direction of the arrow printed on the cover. Now replace the bolt or tighten the chain. Whichever you first did.

SOURCE: Door will not close with remote.
The code you are seeing with 5 blinks is "RPM sensor or motor overload." We can eliminate the motor overload because the door is trying to close. The RPM sensor is a small printed circuit board just in front of the motor. It's a snap to replace and is available at any good door opener company. They will know exactly what you are talking about if you ask for an RPM sensor board.

The code for 5 flashes is " Motor overheated or possible RPM sensor failure. Unplug to reset." Also if the door is stuck in the open position it could be the trolley is jammed against the bolt just in front of the motor unit.
