How to fix/adjust Overhead Door 696CD/B Legacy system, when opening, to prevent automatic disconnect when opening.

I have an Overhead Door 696CD/B Legacy system. Recently, when opening the door, it opens too far and I get an automatic disconnect from the STB as the plastic slide hits the motor unit. I've adjusted the 'open' fine adjustment pinion screw, over and over, but it only holds for one or two openings before the disconnects begin to happen again. The pinion screw, or gear, just doesn't seem to hold the adjustment. Should I be doing anything else?

Ok well the best advise I can give you is to open up your opener case should be a 1/4 nut driver or a Philips head screw driver. Make sure to unplug it first. Once the case is off, find a reqtangle black box with three white plastic screws they are what controls the limits. Chances are they got knocked off wheny ou were putting in the gear. check to make sure the wires are hooked up and find the placement of the limits make sure they can touch each other. Little tip I do for my customs is get a piece of sand paper and rub it agaist the metal contacts for the limits only. (after time lift master openers bind up a film and dont stop where they supposed to.) If your still not sure how the limits work plus in the opener and run it make sure not to put your hands inside the opener and nothing esle is in the way. Then adjest the limits as needed. That should take care of you if not go ahead and make another post ill check back with you.

SOURCE: Door opens after closing

If the main light flashes 10 times when the door reverses it is a door sensor problem but if the door is hitting the floor and reversing and the main light is not flashing then the door is closing too far and the safety thinks it has hit something. On the side of the motor unit you will find 2 controls. One of these is the 'down limit'. Turn this in the opposite direction of the arrow printed on the cover until the door closes but does not reverse.

SOURCE: garage door doesn't open and close properly

Loosen the chain enough so that you can remove it from the sprocket above the motor unit. With the door closed run the motor until the sprocket turns clockwise and stops. With everything attached replace and tighten the chain. Some adjusting of the up and down limits will probably be required.

Door won't close

Your not clear what is going on but my door would not close because the sensor near the bottom of the door as not lined up with the other side. they both have to be in line with each other and also if there is dirt even a leaf over the sensor on either side it won't work either. Is your sensor wire on the over head box out in the open where it should be? If its not opener problem I don't know as you are not clear.

Door closes and then open automatically

if this is a garage door, look in your manual and you may have to adjust your limits, typically done with a couple set screws or buttons on the overhead door unit.

How to reset automatic sliding door on chevy venture van

The rear side door actuator control modules monitor the power sliding door positions at all times. Whenever the battery positive voltage supply to a rear side door actuator control module has been removed or the on-board diagnostics have been activated the power sliding door system(s) must be re-initialized. Re-initialize the right or left power sliding door systems using the following steps:
  1. Turn the ON/OFF switch for the power sliding door system to be re-initialized to the OFF position.
  2. Manually open the power sliding door completely.
  3. Manually close and latch the power sliding door.
  4. Turn the power sliding door ON/OFF switch to the ON position.
  5. Open the power sliding door completely using the B-pillar or overhead console OPEN/CLOSE switch.
  6. Close the power sliding door completely using the B-pillar or overhead console OPEN/CLOSE switch.

Automatic seatbelts and radio do not work

There is a tester that allows the technician to check the different parts of the systems for parts failure, if you want to fix it then your best bet is to go to a dealer for repair.

PLEASE READ claims they have factory repair manuals, they have nothing of the sort, this is false advertising, we experts are not employed by, we help free of charge as much as we can with the general automotive knowledge we have learned while working as auto technicians, I think allot of people don't understand this,
