    I'm on the trail of a similar problem with my Wickes 203004 (same as LiftMaster 2000 I am 99% sure).

    I've been trying to pin down the symptoms for weeks, seems like it is fixed then goes wring again. I've deleted codes then reloaded from the remote and it works sometimes for 4 or 5 goes, bit sometimes only once!

    Anyway, smething I usually with anything electrical first off if the give them a smart smack with palm of my hand because it can show up dry joints in wiring etc etc.

    Anyway ... I've just done this to the motor unit of the door opener and it seems to work correctly each and every time as long as smack it (it's very naughty! lol).

    I am now suspecting a sticking relay ... this would account for the symptoms I've been getting and why it was working as 'one shot up' or 'one shot down' if left for a while.

    I'll let you know how I get on.

My Craftsman garage door opener opens the door fine, then the door rolls back about 6 inches. I little history - this started after I replaced the drive cogs in the unit.

This is an unusual complaint and I have an idea your door is opening just a little too far. On the side of the motor unit you will find the 'up limit' control. Turn this a complete turn in the opposite direction of the arrow printed on the cover. See how this works and you may have to tweak it a bit to get it right.

I have liftmaster professional garage door opener. it opens ok but does not close with remote and light keeps flashing on garage door opener. I checked both sensors and seems like the sending sensor light...

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.

The green light flashing 4 times is sending the code for " Safety reversing sensorsslightly misaligned (dim or flashing LED)". These are the sensors in the doorway. Tweak them a bit.

Garage door shuts down, need to press reset to get it to work

On the side of the opener you will find the down limit control. Turn this a bit in the opposite direction of the arrow printed on the cover. You will probably have to tweak it a bit to get it just right.

After opening, my automatic garage door creeps back down a bit

There is a sensitivity switch for both directions, open and close. If you access the garage door opener in the ceiling, you will see two adjustment screws for calibrating these. I would highly recommend following the instructions in your manual, as these are life safety adjustments! Your sensitivity for closing the door is adjusted to the positive. You just need to back it off a little. Place a 2x4 on the floor of the garage where the door comes down. and when the door hits the 2x4, it should automatically come back up. If not, you adjusted it too far. Hope this helps. and remember, check the manual for your specific adjustment procedures.
