Old 1/3 hp sears craftsman garage door opener

I have an old garage door opener that I no longer use (I used it once just after I moved in 6 years ago and it started smoking) and I want to disable the timer on the light so it will stay on all the time. Anyone have any idea how to do this? I have already disabled the button controls by the door for manuel control, but the light still turns off. Can anybody help?

There is no way to defeat that timer. It is programmed into an integrated circuit on the logic board.

Sears garage door opener 1/2 hp about 6 years old. Will not respond to remotes to open and close. Light flashes on opener when remote is pressed but no door action.

Door sensors are not working. Check if lights are on both sides.
Might be misaligned or one is bad.
Door will close if you hold in the garge close button until it's all the way down.
And it will open on it's own.
You can get these off ebay.

Can you help me? I have a Craftsman HP 1/2 Garage

If the main light flashes 10 times when the door reverses it is your door sensors. Most probably out of alignment but they could always go bad. See if each of them has a small light that should be lit and not flickering. If one of them is out tweak the sensor a bit to see if it will come on. If not one or both is bad.

If the door hits the floor and reverses but the main light does not flash 10 times then the door is traveling too far. On the side of the motor unit you will find the 'down limit'. Turn this in the opposite direction of the arrow printed on the cover. Some adjusting may be necessary.

Sears Craftsman Garage door opener does not open or close

The drive gear is most likely stripped. It is a white nylon gear just in front of the motor. The parts number is 41A2817 and is available from Sears or any good door opener service company. It comes with instructions.

Sears Garage Door Opener automatically opens

Do you live anywhere near a military base? This may sound like a strange question, but the military began using frequencies that are the same as garage door openers, and a lot of people near bases are having trouble with their door openers. These frequencies were reserved some time ago for the military, but weren't used until maybe a year or so ago. Countrycurt0
