Before Starting, Are You Really Up to This Task? Consider Yourself Warned
Before reprogramming your LiftMaster Chamberlain garage door opener yourself, here is life-saving information you must consider:
- Bad or not-precise enough adjustments you make to the garage door travail limits will interfere with the functioning of the safety reversal system.
- If your garage door opener needs too much force to close your garage door (because the garage door tracks are dirty or stuck in ice, for example), it will interfere with the functioning of the safety reversal system.
- If your garage door opener is an old model, you should NEVER EVER use the force adjustments to make up for a binding garage door.
- After reprogramming your garage door opener travel, YOU MUST TEST your garage door opener safety reversal system.
- Make sure your SUV, pick-up truck or any other high vehicles won’t get damaged. Test your garage door to see if it fully opens and provides all the clearance you need.
Without a well-functioning safety reversal system, people, especially small children, could be SERIOUSLY INJURED or KILLED BY A CLOSING GARAGE DOOR. If you are not a skilled and experienced handyman or handywoman, you should NOT do this yourself. Contact certified LiftMaster Chamberlain installers and technicians near you.
Never forget that your garage door is the largest moving object of your house. It’s wall that open and close! Garage doors’springs are under extreme tension. Furthermore, how much do you really know about motors and how they work?
