A Sliding Glass Door Latch Won't Catch During Cold Weather


The framing around windows and doors in your home expand and contract in response to the temperature outside. The framing around the sliding glass door is no different. During the winter and fall, wood contracts because of a lack of moisture, while metal always contracts at lower temperatures. When this happens, you may find that the latch to windows, doors or sliding doors will not operate correctly. Fortunately all major manufacturers provide adjustable door locks. A sliding glass door latch that won't catch during cold weather requires only minor adjustment to correct the contraction of the frame.

Things You'll Need

  • Phillips-head screwdriver
  • Open the sliding door so you can access the front of the lock on the door panel and strike plate on the door frame.

  • Loosen the screws securing the strike plate to the door frame with a Phillips-head screwdriver. The strike plate is where the door secures to the frame when you engage the latch. Slide the plate up or down so the hole in the plate lines up with the hole in the frame housing the latch mechanism. Tighten the screws to secure the plate.

  • Find the adjustment screw for the latch on the edge of the sliding door. The adjustment screw is usually above the latch mechanism.

  • Turn the adjustment screw counterclockwise one full turn with the Phillips-head screwdriver. Attempt to close the sliding door and engage the lock. If the lock does not catch, continue making adjustments as necessary until the door latch engages the catch on the door frame.
