Sears Garage Opener- problem model 139.53635SRT

If your door doesnt have optical sensors looking for obstruction as well as auito reverse I would just replace the opener.

Openers are so cheap and much safer....

Incidently its near impossible to sell a home today with the older opener that lacks optical reverse.

better safe than sorry, optical reverse was mandated after little kids got killed by doors.

Its REALLY worth the bucks, and besides newer openers with rolling code technology are more secure too

Sorry forgot to mention that my opener does have optical sensors and they do work.

when we discovered the same problem, we got a brand new quieter belt driven model installed for $59. plus opener around $200. safer and quieter than old chain drive noise. replace it or car and kid damage warning.

Sorry forgot to mention that my opener does have optical sensors and they do work.

If the adjustment screws are directly under the terminals that the wall button & photo-cell wires are connected to you are adjusting the right ones. Turn the down down as low as it will go w/ the door open. In most cases the door will reverse very quickly or won't close at all.

If your top section hasn't been braced properly (metal strut across top of door, piece of angle on the vertical metal stile from the bottom of the strut to the hinge on the bottom of the top section) the door may not reverse properly before causing damage.

A better test is to use a full roll of paper towels as they usually won't damage the door if it doesn't reverse.

The opener is not expected to reverse if it is within 1" from the floor when it hits something, otherwise it would reverse off the floor.

The limit switch has nothing to do w/ the reverse mechanism. It simply tells the motor when to stop once the door is fully open or closed.

I have Sears crafsman garage door opener 1/2 HP Model#139.53513 aroud

I do not have photo cells or eyes installed on this garage door (I guess this 1989 model) and I just bought a townhome four moths ago..I requested to the seller to have photo eyes installed but my request was turned down because the garage door is working..

qhen i go to

in their search i type in "garage opener" and it goes to:

BuffaloBill, One more question..you mentioned belt drive garage door opener thing is our bedroom is right above the garage..would you be able to tell me which brand you bought..

Ahh while were at it!

Consider the chance the door is stiff, when was the last time these doors were lubed?

Another thing if the door springs might be out of adjustement, stretched after a lifetime of holding the door up AND if your door has those long stretched springs do they have safety cables?

Theres always the chance a spring might break and flail around hitting someone.

No the limit switch would not help. Turn the pressure switch to zero (the one you turned before) If you have 2 down prssure switchs which you should turn both to zero to see which is the down pressure and which one is the up pressure. If this does not seem to help see if you can order new pressure switchs. If not I suggest a Liftmaster Belt drive if you are planning to stay at your residence a while . Hope I helped!

1. Is your spring broken?
2. Could your spring have slipped?
3. What is the height of your door?
4. Are you able to count the number of turns that your spring is wound?
5. If you release the door by pulling the manual disconnect cord are you able to lift the door manually?
