Craftsman garage door opener remote

The learn button is located on the garage door opener unit itself that hangs from the ceiling. If you follow the gray antenna up to the unit you will see a red/orange button on the unit. That is the learn button. When you push that button and amber LED will light up either above or next to the learn button. This indicates that the garage door opener is now ready to learn a new device. Press and hold the button you want programed on the garage door opener remote and release it. The garage door opener will click and the garage door opener light will go off and come back on (if the light bulbs are in working order). The amber LED will go out, repeat if you need to program anything else.

I think the adjustment mode is on.

For example, that's from Craftsman manual:

""
Setting the Force
The force setting button is located on the left panel of the motor unit. The force setting measures the amount of force required to open and close the door.
1. Locate the purple button on the left panel of the motor unit (Figure 1).
2. Push the purple button twice to enter the opener into Force Adjustment Mode (Figure 2). The LED (Indicator Light) will flash quickly.
3. Push the remote control or control console (Figure 3). The door will travel to the DOWN (close) position.

Actually, you should just read carefully your garage door opener unit's manual.

Nothing wrong with the sensors. They don't work when the door is opening anyway. Only when closing. Make sure the light in the wall control is not flashing. If it is press and hold the lock button for 3 seconds.

If your sensors are not pointed at one another the light on one of them will go out. Tweak them a bit. If you cannot get the light to come on then your sensors are bad.

If it is the right remote for your opener try programming like this. Press and hold the button on the and then press and release the smart/learn button. If this doesn't work you have a bad remote.

I would first of all unplug the opener for at least 15 minutes and see if it doesn't reset. If not, pull the logic board and check for burnt or missing traces on the printed circuit board.

To answer your question the opener is in vacation mode. Press and hold for 3 seconds the button on your wall control with the lock icon. The green light will stop flashing and you will be back in business.

Sounds like you have a bad logic board.

I think this is an easier way to program. Press and hold the button on the remote and then press and immediately release the smart/learn button on the rear of the motor unit. Do this for each remote you have.

a component in the wall unit is failing , that makes the conection happen when the remote signal is recieved , ( it is recieving the remote signal but not sending it out to the control circuit for the motor )
