Intermittant problem Sears 139.53646 SRT opener. Opener light goes on and off and relay clicks when is use or when I hit it on the side of the opener. Happens with door connected and disconnected. Green light on push button goes off when main opener light goes off. Seems like overall power to the unit turns on and off.

    My 13 year old Craftsman unit suddenly quit working. All it does when the control button is pushed, is a click the light comes on and then a wurr from the motor for about a second and then it quits.
    I have disengaged the door fron the chain, but the same happens.

Look at the lights on the safety eyes also. If all of these lights go off at the same time, there is definately a power issue. It is either an issue with the electical outlet or the circuit board.

Door sensors have nothing to do with door opening. Only closing. It sounds like you have a bad gear in the motor unit. Remove the cover and it will be obvious if the gear is bad.

Where is the "SRT" button on model 139.53876? Thanks


The model number you give is for a wireless keypad. They don't have SRT buttons. The model number for the opener is on the door side of the motor unit.

I have model 139.53671 SRT gagrage door opener


If that is the right remote for the opener you need to locate the smart/learn button which is on the rear of your opener near where all those white wires go. Hold the button down on the remote and then press and immediately release the smart/learn button. It should now be programmed.
