move your recorder close to your PC then connect the recorders DVD drive to your PC turn one the PC and eject the disk remove the draw front then retest it. if this doesn't work The machine may have a mechanical issue in the door mechanism that you cannot fix yourself. You will need to take it to a service technician. Don't try to pry the door open. Doing so will void any warranty and also possibly expose you to dangerous laser emissions.good luck happy holiday

When u press the door button the signal is sent to a circuit board that sends the signal to open the door, the switch is just a ground signal, this circuit board is defective, if the unit is old u might contemplate replacing it, the repair cost will be very high, most likely $100's.

Hello derjuice

You need to take off the outer panel and then manually open the door by moving the mechanisms once the outer panel is off. Sounds like the main circuit board may be fried. Does anything work on it still?

I have a Samsung DVD R160 recorder. A few days ago the recorder was not on and it was making a noise like it was trying to read a disk. This went on for quite a while. I then turned it on and it would...


Try this, look for a small hole on the front of the unit.Use a pin and press in to see if it opens,ejects the disk .If no hole try seeing if you can press ,lift,pull at the door/slot while pressing the open door/eject either on the unit or with the remote control.It sounds like you may have a bad CD/DVD (copy) that the unit is trying to read/load but can't. keep trying to eject CD/DVD if this doesn't work unplug unit for 5 minutes,try open door again do press and hold open repeatedly I know it's frustrating but it just may eject.Don't use this recorder for playback of DVD buy a $30 DVD player the cheaper the better they play anything.GOOD LUCK

You most likely have a bad wall control or the wiring to it. An easy way to check this is to remove the connection at terminal #1 on the rear of the motor unit. Just remember that your wall control will not work with this wire off. Your remotes will still work though.

Door opens by itself in storm


Here are some things you can check.

Look at the LED light next to the SMART/LEARN button on rear of the motor unit. You may need to remove a light lens cover in order to see it. If the light is flashing rapidly this means you have a stuck button on one of your remote controls. Take the batteries out of each remote control. When you remove the batteries from the bad remote, the light will stop flashing. This remote needs to be replaced.


If one of your neighbors remote controls is inadvertently programmed into your receiver, you door will open when their remote is activated. If this happens you will need to clear out your receiver and reprogram your remote controls. Press and hold the smart/learn button for 6 seconds or until you see the small LED light near the button turn itself off. If the above steps have been followed and the symptoms continue, there may be an electronic short in either the wall control button or the receiver logic board. In this case, remove the wall control wires from terminals 1 and 2 on the motor unit. Should the symptoms persist after the wires are removed, replace the receiver logic board. If the symptoms stop with the wall control wires removed from the motor unit, replace the wall control button, and the wires leading to the wall control button.
