How to Fix a Warped Cabinet Door
- 1). Remove the door hinge from the cabinet by loosening the screws that secure the hinge to the cabinet.
- 2). Attach the two L-brackets on opposite corners of the door using screws and a power drill. Place a screw in each hole of the L-bracket and fasten the brackets to the door using a power drill.
- 3). Measure the size of truss rod needed by measuring between the two L-bracket mounting points. Measure the length of the threaded insert. Subtract the total distance between the L-brackets by the length of the threaded rod. Subtract an additional 1/2-inch for adjustment. Divide this number by two. This will give you the length of the two truss rods.
- 4). Cut the truss rods to the appropriate size using a hack saw.
- 5). Place each truss rod into the hole on the L-bracket and tighten the nut on the side using a ratchet and socket. Insert the threaded rod between the two truss rods. Thread the threaded rod into each truss rod.
- 6). Tighten the threaded rod using a wrench until the two corners of the door are pulled together enough to eliminate the warp.
- 7). Re-attach the door to the cabinet using a power drill.
