Repairing Broken Bi-Fold Doors

Top Stationary Hardware

• 1

  Correct a door that does not close smoothly by adjusting the top stationary hardware.

• 2

  Locate the spring pivot pin at the top of the door close to the jamb and use your finger to press it down. Lift the top of the door outward then lift the door to remove it from the jamb.

• 3

  Look at the hardware attached to the jamb at the top of the door frame and locate the pivot hole where the spring pivot pin was seated. Next to this is a Phillips head screw. Loosen the screw and move the hardware toward or away from the jamb, as needed, to re-align the door then re-tighten the screw.

• 4

  Put the door back into the jamb and check the placement to see if the problem is corrected. If not, repeat the adjustment and check it again.

Bottom Stationary Hardware

• 5

  Locate the hardware at the bottom of the door jamb. This hardware is attached to the floor and has two rows of teeth, or grippers, that run parallel to each other.

• 6

  Find the shaft in the corresponding area on the bottom of the door. The shaft has a ridged cap on the end that fits snugly into the teeth and holds the bottom of the door in position. The parallel set of teeth are longer than the ridged cap. This allows you to position the ridged cap at any point along the teeth to move the door bottom closer or farther away from the jamb.

• 7

  Lift the door and the shaft up and off the row of teeth and set them back down in their new position on the teeth. The ridged cap seats in the teeth and holds the door in its new position.

• 8

  Test the door to be certain the problem is resolved. If not, lift the door and correct the positioning of the ridged cap again until it is where you need it to be.

Bi-Fold Wheels

• 9

  Remove the door from the jamb.

• 10

  Unscrew the piece of hardware that contains the wheel mechanism with a Phillips head screwdriver.

• 11

  Choose a replacement wheel assembly by taking the old one with you to the hardware store to find the right part.

• 12

  Screw the new wheel assembly in place where the old one was. Replace the door and make sure the wheel is positioned in the track. Carefully open and close the door to be sure the wheel is seated properly.

Wheel Track

• 13

  Remove the door from the jamb if the wheel track is bent or damaged. When this happens, the door will be difficult to open and close or may fall out of the jamb.

• 14

  Unscrew the old track with a Phillips head screwdriver and remove it from the jamb, along with the spring pivot pin hardware.

• 15

  Screw the new track in place and reinstall the spring pivot pin hardware.

• 16

  Replace the door and seat the wheel in the track. Be sure that the wheel moves easily and securely in the new track.

Handle

• 17

  Remove the door handle by unscrewing it from the long screw that secures it to the door. This will require either a flat head or Phillips head screwdriver. The screw head is typically located on the back of the door behind the handle.

• 18

  Replace the old screw if it is stripped or in some way unserviceable. Place the new long screw through the existing hole in the back of the door.

• 19

  Thread the new handle onto the screw from the front of the door. Tighten down the screw firmly so that the handle is secure.
