If the main light flashes 10 times when you try to close the door it is a problem with the door sensors. Make sure they are pointed at one another and the small light on each one is lit and not flickering. Tweak them a little. If you can't get both lights to come on you have bad sensors.

If disk door wont open - stays locked


I called Samsung who suggested pushinhg the play button on the panel and the power button on the remote together. "No disc" eventually showed on the screen and pushing the open/close door button worked.

However, my remote wouldn't work, even after changing batteries.
The machine did play. Unfortunately, later that night I tried another DVD and it locked up again. The next day I tried the above 2-step and it worked again, so maybe the other DVD caused trouble. But I cant get my remote to do anything except the 2-step listed above.

I don't use the player very often.

I have a Craftsman keyless gargage door opener model 031D0431. We just moved in and would like directions on how to recode the keyless entry. One more question...if I recode the keyless entry, do I have...


Coding the keypad will not affect the remotes if you follow these directions.

Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to your keypad and key in a four digit code and press enter.

Remote won't work since I changed the code on the garage door opener


thats because you didn't recode the remote to the garage door or you have not recoded it correctly. double check the remotes settings (if it can be changed) to ensure it matches the door opener. Now, if you cannot see any method of changing the remote to suit the main unit, it may be that the remote is factory coded or that it is coded by Soldering links on the circuit board. Carefully disassemble the remote to have a look if it does not have a small bank of switches in the battery compartment. If the switches are there, check the coding is the same as the main unit, if the switches are not there, disassemble and check for solder links on the circuit board. If you are not confident with using a soldering iron, take the remote to someone who is.

Intermittent remote trouble


Your wall control is hard wired and doesn't use the receiver portion of the logic board. The remotes do. Your receiver is going bad.

To program the remotes, hold the button down on the remote and then press and immediately release the smart/learn button.

For the keypad, press and immediately release the smart/learn button and walk over and key in your four digit code and press enter.

Problem with my Craftsman 139.53879


when you have to be closer to garage to make remote work tells you battery is going low. Do you have a LOCK or VACATION button. Make sure it is off. May need to recode remotes. See manual for how. Very easy
