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.

SOURCE: Remotes don't work

I recently had Verizon FIOS equipment installed in my garage (for phone, internet and TV), which is plugged into a 110 volt electrical outlet. Thinking this equipment might be causing some RF interference, I unplugged the FIOS equipment, and both garage door openers immediately worked perfectly again!
After reconnecting the FIOS equipment, I then plugged the garage door opener into a different electrical outlet approximately 15 ft. away via an extension cord, and the openers continue to work fine. Fingers crossed, I hope the issue is permanently resolved.

Look at your manuel find the page that shows the limit access switch. (Unplug your opener.) It isn't really a switch, but the three white plastic screw like parts. The center has a brown wire connected to it, which has a metal piece that is as wide as all three white screws. The outside screws are your limit access stop guides, one for the up control stop guide and the other for the down control stop guide. If the center screw with the metal part gets caught behind on of the stop guides the motor will not engage. Gently move metal piece from behind the stop guide.

SOURCE: My Craftsman 53684 keyless won't work with my Craftsman 53930DM.

I've never seen the first set of steps you mention. You always need to press the "learn" button first so the opener will be in the mode to capture the new code. As far as I know it is not necessary to hold the Enter button on the keypad (at least I never have). While the "learn" LED is lit on the opener, just key in the new code and press Enter.

Maybe you should try clearing the receiver first by pressing the "learn" button and holding it until the LED either goes out or starts flashing (depends on model). Then try reprogramming. Maybe the little computer is confused.

If the lights in the door sensors do not light you have either a bad logic board or bad wiring to the sensors. Replacing the logic board is usually the cure.

If when closing the door it reverses to the open position and the main light flashes 10 times it is a door sensor problem. Make sure the small light on each sensor is on and not flickering ever so slightly. (check closely) Tweak them a little even though they may seem to be okay. Check for 5vdc between terminals 2 and 3 on the rear of the motor unit. If there is no voltage or if it is greater than 6vdc the logic board is bad.

You are going to have to find where you are losing power. The most likely place is the logic board especially if you have had any electrical storms or power surges. Remove the board and check for loose or missing traces on the printed circuit.

It sounds like you have a remote with the button pressed or broken so that it is on all the time. Remove the batteries from your remotes and check that light. The rapid flashing is an indication that it is receiving a signal. Make sure you don't have an old remote in a drawer somewhere.
