Setting Your Garage Door Limit Buttons To Raise The Height

As cars have gotten bigger and bigger, those who have older houses (or some newer homes) somtimes find that new SUV’s don’t fit underneath the garage
door. Before you get a higher garage built, see if you can enlarge the
area just enough to accommodate the new automobile.

First, measure the actual opening of the complete garage, width and height. If if these measurments of the car is less than the physical opening of the garage, you can probably increase the height of the door opening by playing with the limit switches on your garage door motor. Always, any work on a door entails some amount of danger, due to the system of springs, pulleys, and cables. You may want to call a professional garage door repair company.

If you think you want to complete the job by yourself, give yourself plenty of time. The changes need to be made in small amounts, so can be somewhat
time-consuming for a worker who has never worked with limit switches before. You will need a small ladder, a flat head screwdriver, and a helper.

With the garage door down, place the stepladder under the motor and look for the limit switches. You will see them as two little knobs that have slots which are made for a flat head screwdriver. Usually, the switches are on the back of the console, but on some models they can be located near the light bulb. Tell your helper to press the wall button to open up the door. When it has opened completly, use your flat head screwdriver to turn the open limit screw clockwise. By turning this switch clockwise, it will increase the upward travel of the garage. Make the adjustments in tiny increments. Every
full turn is a three inch change, but don’t attempt the full three inches at one time. A quarter turn, at the most, is good for one time. After each adjustment, ask your helper to close, then reopen, the door by pushing the button on the wall console. Keep on changing the limit switch until the opening is high enough to hold your new vehicle.

When you’re up on the step ladder, you might want to look at the bottom of the door too. The door should seal to the floor tightly, but should not come down so forcefully that it makes any sound as it touches the ground. If the door drops with a thud, you need to change the down limit by turning it clockwise with your flat head screwdriver, again in tiny increments. On the other hand, if the door does not shut with a tight seal, you should make small adjustments by turning the down limit counterclockwise — in very small adjustments — until you have a snug seal.
