This is cause when there is something blocking one of the sensors. Look on each side of your garage door near the concrete when the door is closed and you will see small sensors that are facing each other.. Make sure they are not misaligned and that nothing is in front of them.

I have a Sears craftsman model 139.53637SRT garage door opener. My remote has not worked in a long time. I use the wall control button and have to hold the button in order to open or close the garage door....


It sounds like your door sensors may be bad or misaligned. Make sure the small light on each sensor is lit and not flickering. That could be the cause of your having to hold the wall button down until the door is closed. You can buy a universal remote but if you only had one remote before it could be the receiver that has quit. A new remote would not fix that but the only way to find out is to try.

When the door closes, it automatically reopens. There are no obstructions so that isn't the issue. If I disconnect the door and cycle the automatic is closes and then immediately reopens.


make sure that the auto matic reverse circuit light is being read correctly. they is a light extending a beam of infared light, you can't see it, to a reflector across the garage at the floor level at the garage opening. There should be an indicator light, usually green and red. Line up the light and reflector until the green light comes on.

When i use the keypad or internal button to close my garage it will begin to close then immediately reopen. The sensors are clear and nothing is causing the door to stop closing and reopen. What do you...


make sure the sensors are properly aligned. disconnect the opener with the saftey release and operate the door manually. be sure the door opens and closes reasonably easy by hand. If not, check for binding or broken springs or torsion springs

Upon pressing open/close button kitchen door the garage starts to close but then reopens after 3-4". one must then hold button until door is fully closed. what is remedy?


The problem is that your system does NOT "see" the safety "eyes" sensors. Make sure that your sensors are properly connected to the opener (both sensors should have lights on them, one amber and another green). If they do not, check the wiring and the connections at the opener itself.

You need to do is shade the eyes some how for th door to work. What I did was remove them and put them up by the opener so the sun does not get to them.

Garage door


TRY THE DOOR MANUALLY AND RUN THE OPENER DISCONNECTED FROM THE DOOR(WITH DOOR IN CLOSED POSITION).

THIS SHOULD ISOLATE THE PROBLEM (ACTUAL DOOR PROBLEM OR OPERATOR PROBLEM).

HOLDING DOWN THE WALL BUTTON OVERRIDES THE SAFETY EYES.
WHEN HOLDING IT DOWN MAKES THE DOOR CLOSE PROPERLY THE PROBLEM IS IN THE SAFETY EYES.

ARE BOTH LEDS ON? - CHECK FOR A LOOSE OR BROKEN WIRE.
ARE THE EYES WIRED CORRECTLY?
ARE THEY AIMED AT EACH OTHER?

IF THE DOOR STOPS/REVERSES (WITH DOOR CONNECTED) WHILE HOLDING DOWN THE WALL BUTTON TO CLOSE YOU NEED TO CHECK THE SENSITIVITY ADJUSTMENT.

HOPE THIS HELPS
