A few dabs of clear, hot glue in the panel seam can prevent a cabinet door from rattling and not require disassembly or changing the look of the panel.
Here’s my approach to silencing a rattling cabinet door panel. I pull out my hot-melt glue gun and apply a few small beads of transparent glue into the seam where the panel meets the door frame on the back side. On solid wood panels, center the glue so the panel can expand and contract across the grain. Trim off the excess for an inconspicuous fix.
