Wood – How to fix a warped kitchen cabinet

cabinetskitchenswoodwoodworking

The side wall of the cabinet is slightly warped after I used the high temperature self-clean feature on the oven. This cabinet has three large drawers in it and now they won't close. The wall of the cabinet is warping in slightly (a few millimeters) and is squeezing the drawers enough that they scrape against the side of the cabinet.

How should I repair this cabinet?

I decided to try to install a cross brace inside the cabinet to spread the walls enough so the drawers would fit.

I made a trip to the hardware store and picked up:

  • A 1x6 pine board
  • Angle brackets with screws

Then I:

  1. measured the front opening of the cabinet.
  2. cut a piece off the pine board 2mm longer than the cabinet is wide.
  3. used a rubber mallet to tap the board into place as a cross brace just underneath the top drawer.
  4. tested the drawers to make sure they opened and closed with the cross brace in place
  5. permanently attached the cross brace with the angle brackets.

It works perfectly. I was prepared to add a second cross brace underneath the middle drawer, but all the drawers are working well without it.

Here is a picture of the repair with a red circle around the board that I added.
