The remote works only intermittently. Sometimes it will work for a day or two then quits. The keypad just quit working and seems as if it isn't even connecting although it was working fine until a couple of weeks ago

Problems with more than one remote unit is most always a receiver problem. The receiver is part of the logic board.

Access system for 3/4 hp belt drive works sometimes, however with change in temp, climate conditions, the system does not work at all. a few days later the system will work without any adjustments

Some electronic components become sensitive to temperature changes and will quit working. If you have more than one remote unit and the problem exists with them all then your logic board is bad.

I have sears opener #139.53989. Every once in a while I have a down problem. It goes down within an inch of the floor and reverses. Sometimes I can hold the wired remote button and it will go all the way...

If the main light flashes 10 times when the door reverses it is a sensor problem. Check them very closely. If they are just a little off one of them will be flickering but it is difficult to see. This can also cause the problem to be intermittent. Tweak them just a little.

It is normal for that light to blink randomly.

My garage door remote will work for a day or two then it quits and then I have to reprogram it, and it works another few times and stops

If you only have one remote it could be it or the receiver that is quitting. No way to tell without another remote to test it.

Code Remote and other remotes do not all work at the same time.

Either your keypad has reverted to an earlier technology and will no longer work properly with your opener or you have the wrong keypad. Either way take the model number off the main unit and get the correct keypad.

KEYPAD WON'T WORK AFTER REPLACING BATTERY

A few questions...
Does the remote work very close to the garage, but not farther away - If so, then likely IS a battery problem....

Is the weather very cold where you live? - battery strength diminished quite a bit in the cold (try keeping the remote indoors for awhile & see what the results are). Also could be moisture in your unit - keep it inside & on a warm ( but NOT HOT ) surface for a day or 2

Did you get a good battery with an indicated shelf-life that is a couple of years into the future? (some 'dollar store' batteries are not very good). Also Alkaline batteries (if permitted by the user manual) are quite a bit more powerful than even the 'heavy duty' batteries of the same brand.

Finally, Is your unit at the garage powered electrically, or is it a battery also? If the garage portion is battery operated, try replacing that battery (in your receiving unit).

Hope at least 1 of these ideas helps...
